For a volunteer-run education community, Discourse is probably the closest fit if the priority is no platform transaction fees + straightforward moderation.

• Discourse — Its hosted Free plan is $0, with unlimited members, two staff seats, discussion forums, chat, trust levels, flags/review queues, and membership/permission controls. There are no platform fees on community contributions because it isn't a payment marketplace. Discourse Discourse - Civilized Discussion
• Self-hosted Discourse — The software is open source and free; you'd only pay for hosting (or use donated/community infrastructure). This gives you more control but requires someone to handle updates, backups, and server administration. Discourse - Civilized Discussion
• Canvas Free-for-Teacher / Canvas Lite — Better if the project is primarily about courses, assignments, submissions, and teaching, rather than a community discussion space. Canvas Lite is being launched for community instructors and tutors at no cost. Instructure Instructure
• OpenEduCat Community Edition — Worth considering if you need a more traditional LMS/school-management system. It's open source with no per-user licensing fees, but self-hosting means taking on technical administration. OpenEduCat

Practical choice

If your project looks like “volunteers teach, members discuss lessons, ask questions, share resources, and admins moderate”, I'd lean toward Discourse Free. Its moderation model is particularly suitable for a small volunteer team: flags, review queues, trust levels, and granular permissions are built in. Discourse - Civilized Discussion Discourse - Civilized Discussion

If you tell me whether you need actual course/LMS features (assignments, quizzes, certificates, student progress) or mainly a community/forum, I can narrow it down to 2–3 options and compare their costs and moderation features.

For a volunteer-run education community, Discourse is probably the closest fit.

• Cost: Its hosted Free plan is $0, with unlimited members and chat. Discourse Discourse - Civilized Discussion
• No platform/transaction fee: It isn't structured around taking a percentage of member activity or payments; its hosted plans use flat pricing. Discourse - Civilized Discussion
• Moderation: Built-in flags, review queues, automated checks, permissions, and trust levels let volunteers share moderation duties. Discourse - Civilized Discussion
• Good for education: Its topic/category structure works well for lessons, questions, resources, announcements, and volunteer discussions.
• Two caveats: The free hosted plan currently provides 2 staff seats and a discourse.group subdomain. Discourse - Civilized Discussion If you need more admins, you can either upgrade or self-host the open-source software; self-hosting eliminates the software fee but still requires hosting/technical maintenance. Discourse - Civilized Discussion

Discord is another $0 option and has built-in AutoMod, but it's more oriented toward real-time chat than an organized, searchable educational knowledge base. Discord

So if your priority is “volunteer-run + essentially no platform fees + basic moderation + organized educational discussions,” Discourse is a particularly direct fit. Discourse - Civilized Discussion

For that use case, Discourse is probably the strongest fit.

• Cost: Discourse currently has a $0 hosted plan with unlimited members, unlimited chat, and two staff seats. Discourse Discourse - Civilized Discussion
• Moderation: It includes moderator/admin tools, post flagging, review queues, automated checks, membership controls, permissions, and trust levels. Discourse
• No platform transaction fees: It isn't built around taking a percentage of donations or memberships. If you later self-host it, the software itself is 100% free and open source; you'd just pay your own hosting costs. Discourse - Civilized Discussion GitHub
• Good for education: Its topic/thread structure works particularly well for lessons, Q&A, resource discussions, volunteer coordination, and an archive of searchable knowledge.

discourse.org

One caveat

The free hosted plan has 2 staff seats, so if "volunteer admins" means three or more people need formal moderator/admin access, you'd either need a paid plan or self-host Discourse. Discourse - Civilized Discussion

If your project needs actual course/LMS functionality (lessons, quizzes, assignments, student progress) rather than primarily a community forum, I'd choose differently. I can also compare 3–5 free options specifically for a volunteer-run education project, including Moodle, Discourse, and community/chat platforms.

For a volunteer-run education community, Discourse is probably the best fit if your priority is no platform fees + straightforward moderation.

• discourse.org — $0, unlimited members, 2 admin/moderator (“staff”) seats, hosted for you, and includes flags, a moderation review queue, trust levels, and membership controls. There are no transaction/platform fees because the free community isn't a paid-membership product. Discourse Discourse - Civilized Discussion
• Discourse self-hosted — If you have someone technical volunteering, the software is open source and free; you only pay for inexpensive server hosting. This gives you more control and avoids hosted-platform fees entirely. Discourse - Civilized Discussion Discourse - Civilized Discussion
• Discord — Also free for ordinary community use and has built-in AutoMod, making it attractive if your project is more chat-oriented. However, it's less suitable than Discourse for building a durable, searchable educational knowledge base. Discord Support

My pick: Discourse Free for a community where volunteers need to organize lessons, questions, resources, and discussions. It gives you a proper forum structure without requiring someone to maintain a server. The main limitation is 2 staff seats on the free hosted plan. Discourse - Civilized Discussion

If you tell me roughly how many learners and volunteer admins you expect, I can narrow this down to 2–3 options and compare moderation, privacy, storage, and long-term cost.

For a volunteer-run education community, Discourse is probably the strongest fit.

• $0 hosted option: Discourse now offers a free hosted plan with unlimited members and chat, a free discourse.group subdomain, and 2 staff seats for admins/moderators. Discourse Discourse - Civilized Discussion
• Basic moderation is built in: flags, a review queue, automated content checks, trust levels, and granular membership/permission controls. Discourse - Civilized Discussion
• No transaction/platform fees: it isn't a marketplace or course-sales platform taking a cut of donations or memberships. Its pricing is flat rather than per-user. Discourse - Civilized Discussion
• More control if you grow: Discourse is open source, so you can eventually self-host it and pay only for server/hosting costs. Discourse - Civilized Discussion

One caveat

The free hosted tier has only 2 staff seats, so if you have a larger volunteer moderation team, self-hosting or a paid tier may become preferable. Discourse - Civilized Discussion

My pick: Start with Discourse Free if the project is primarily discussion, Q&A, resource sharing, and community support. It gives volunteers substantially more moderation structure than a generic chat platform without charging per member.

discourse.org

If you mean a platform specifically for hosting actual courses/lessons (rather than a community forum), I can also compare the best no-platform-fee options for that use case.

Discourse is probably the best fit. Its free hosted plan has no platform fees, unlimited members, two staff seats, and built-in moderation tools. Discourse Discourse - Civilized Discussion

If you need actual courses/assignments, consider Moodle instead: it’s open-source with no license fees, though you’ll pay for hosting. moodle.com

For a community-run education project with volunteer admins, I’d pick Discourse.

• Free hosted option: Discourse now has a $0 plan with unlimited members, unlimited chat, and 2 staff seats—useful if you have one or two volunteer moderators. Discourse Discourse - Civilized Discussion
• Basic moderation is built in: flags, a review queue, automated content checks, membership controls, permissions, and trust levels. Discourse - Civilized Discussion
• No platform transaction fees: it isn't a course marketplace taking a cut of donations or enrollment payments. The free community plan costs $0.
• More control later: Discourse is open source, so you can self-host it and pay only for hosting if you eventually need more staff accounts or customization. Discourse - Civilized Discussion Discourse - Civilized Discussion
• Good fit for education communities: it's particularly suited to discussion, Q&A, resource sharing, announcements, and peer support rather than being a full LMS.

discourse.org

One caveat: the free hosted plan has only 2 staff seats. If you expect several volunteer moderators, self-hosting is more flexible, or you could consider a low-cost paid plan.

If you need actual courses, assignments, quizzes, and student gradebooks rather than mainly a community/forum, I'd choose a different platform—e.g. Moodle.

For a volunteer-run education project, I’d shortlist Discourse first if the main need is a community/forum, and Moodle if you need actual courses and assignments.

• Discourse — best overall for a community. Its current hosted Free plan is $0, with unlimited members, unlimited chat, two staff seats, and built-in moderation tools such as flagging/review queues, automated checks, and membership controls. There are no per-member or per-admin fees. Discourse - Civilized Discussion Discourse - Civilized Discussion

discourse.org

• Discourse self-hosted — best if “no platform fees” is the priority. The software is 100% open source and free; you only pay for whatever server/hosting you choose. This gives you maximum control, but volunteer admins need some technical ability to maintain it. GitHub Discourse - Civilized Discussion
• Moodle — best for structured education. It is free/open source with no license fees, and supports courses, learners, educators, and administrators. You'd still need hosting and maintenance if self-hosted. Moodle GitHub

moodle.com

My pick: If you're essentially building “a community of learners, volunteers, and educators”, use Discourse. It gives volunteer moderators useful tools without charging based on community size. If the core product is “take courses, submit assignments, track learning”, use Moodle instead.

If you tell me roughly how many learners/admins you expect and whether you need courses/assignments, I can narrow it down to the cheapest practical setup.

For a community-run education project with volunteer admins, I’d pick Discourse.

• $0 hosted option: Discourse now has a free hosted plan with unlimited members and chat, a free *.discourse.group address, and 2 staff seats—enough for a small volunteer admin/mod team. Discourse - Civilized Discussion Discourse
• Good moderation: built-in flagging/review queues, automated checks, membership/permission controls, and trust levels that can give experienced members additional abilities. Discourse - Civilized Discussion
• No platform/transaction fee model: it isn't primarily a paid-course marketplace, so you're not giving the platform a percentage of donations or memberships.
• Open source: if you eventually want complete control, Discourse can be self-hosted for free; you'd only pay for your server/hosting and related infrastructure. Discourse - Civilized Discussion GitHub
• Especially suitable for education: organized topics, searchable discussions, categories, and long-running Q&A work better for an educational community than a social-feed platform.

The main limitation of the free hosted plan is 2 staff seats, plus limits such as 10 categories and 5 GB storage. Discourse - Civilized Discussion

Runner-up: HelloBox looks interesting if you want something more lightweight; it advertises a free-forever plan and paid plans starting at $5/month. hellobox.co But for a volunteer-run educational project where moderation and long-term knowledge organization matter, Discourse is the safer choice.

discourse.org

For a volunteer-run education community, Discourse is probably the best fit right now.

• Cost: Discourse has a $0 hosted plan with unlimited members, unlimited chat, 5 GB storage, and 2 staff seats. Discourse - Civilized Discussion Discourse - Civilized Discussion
• No platform transaction fees: It isn't built around taking a percentage of donations, memberships, or other community payments.
• Moderation: You get flags, a review queue, moderation/admin controls, trust levels, and spam/content-management tools. Discourse - Civilized Discussion Discourse - Civilized Discussion
• Good for education: You can organize subjects/classes into categories, have threaded discussions, search old lessons, and let trusted volunteers gradually take on more community-management abilities.
• Volunteer-friendly: The free hosted tier handles servers, updates, and backups, so admins don't need to maintain infrastructure. Discourse
• If you outgrow it: Discourse is also open source and can be self-hosted, giving the project more control and avoiding dependence on a proprietary platform. Discourse - Civilized Discussion

One caveat

The free hosted plan currently has only 2 staff seats, so if you need 5–10 volunteer moderators, you'd either need a paid plan or self-host Discourse. Discourse - Civilized Discussion

Another option is Lemmy if the project is primarily a Reddit-style discussion community. It's free, open source, decentralized, and has community moderation, but it's more technical to operate and less suited to a structured "courses + lessons + discussion" environment. Lemmy

My pick: Discourse Free for the easiest launch; self-hosted Discourse if having many volunteer admins/moderators while keeping costs near zero is important. Discourse - Civilized Discussion Discourse - Civilized Discussion

discourse.org discourse.org

For a community-run education project with volunteer admins, I’d look for a platform that has:

• $0 or very low operating cost
• No transaction/platform fees
• Admin/moderator roles
• Private groups or member approval
• Basic tools for discussions, resources, and announcements

Good options:

My practical picks:

1. For a learning community (discussion + resources):

Discourse is probably the strongest fit. It feels like a community forum, has good moderation workflows, and avoids per-member fees if self-hosted.

2. For courses with lessons, quizzes, and progress tracking:

Moodle is the better fit. It is designed for education rather than general community chat.

3. For a small volunteer group that wants something easy:

Discord is usually the fastest to launch, though content organization becomes harder as the community grows.

4. For maximum independence and no vendor lock-in:

Use an open-source stack such as Moodle + Discourse, hosted cheaply on a small server.

A few platforms worth avoiding for this use case:

• Community platforms that take a percentage of paid courses or memberships
• Social networks where moderation depends heavily on a parent company’s rules
• Free plans that remove admin controls once the group grows

If you expect under ~500 learners, I’d lean toward Discourse or Discord. If you expect hundreds/thousands of learners with structured lessons, I’d choose Moodle + Discourse. Open-source education projects such as Bluelearn Project show that volunteer-driven learning communities can operate without paywalls or commercial platform models. bluelearn.org

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

• Discourse Free — $0, unlimited members and chat, 2 staff/admin seats, hosted for you, with built-in moderation tools and trust levels. There are no platform/transaction fees because you aren't selling through the platform. blog.discourse.org
• Discourse self-hosted — the software is 100% open source and free; you only pay for whatever server/email infrastructure you choose. This gives you maximum control but requires more technical maintenance. github.com
• Moodle — better if the priority is actual courses, assignments, quizzes, grades, and structured learning rather than community discussion. MoodleCloud is relatively inexpensive but isn't free beyond its trial; current plans start at AUD $170/year for 50 users. www.moodlecloud.com

My recommendation

Use Discourse if the project is primarily a learning community—discussion groups, peer support, announcements, Q&A, resources, and volunteer moderation.

Use self-hosted Moodle if it's primarily an online school/LMS and you need formal courses, assignments, quizzes, and learner progress.

If you tell me roughly how many learners and volunteers you expect, I can narrow this down to the best 2–3 options and compare their actual costs and moderation features.

For a community-run education project with volunteer admins, I’d shortlist these:

discourse.org

• Moodle — best if the project is primarily courses/classes. Moodle itself is open-source and can be self-hosted with no platform fee, but hosting requires some technical work. MoodleCloud is easier but paid after its 28-day trial, starting at $170/year for 50 users. MoodleCloud MoodleCloud

moodlecloud.com

• Hylo — interesting for a broader volunteer/community model. It's free forever and includes discussions, chat, events, projects, groups, roles, and decision-making tools. It's less of a conventional LMS than Moodle. Hylo

My pick

Discourse is probably the sweet spot if you need a community around education—discussion groups, peer support, announcements, volunteer moderation, Q&A, and searchable knowledge—without platform fees. Its free hosted tier removes the need for volunteers to maintain a server. Discourse - Civilized Discussion

If you need quizzes, assignments, grades, course completion, and structured lessons, choose Moodle instead.

If you tell me roughly how many students/members you expect (e.g. 50, 500, 5,000) and whether you need actual course/quiz functionality, I can narrow it to 2–3 options.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list if the priority is $0 platform fees + simple community moderation.

• Includes 2 admin/moderator seats, flags, review queue, automated content checks, and granular membership permissions.
• No per-member or transaction/platform fee. Discourse - Civilized Discussion Discourse - Civilized Discussion
• Particularly good if your project is organized around discussion, Q&A, peer support, and sharing learning resources.
• If you eventually need more admins, self-hosting is also possible because Discourse is open source. GitHub
• moodle.org — Best if it's primarily a learning-management system

• Better suited to structured courses, assignments, quizzes, grades, and learner enrollment.
• The software itself is open source, so self-hosting can avoid platform fees, but you'll need someone to manage hosting and updates.
• MoodleCloud is managed, but its paid plans currently start at about A$170/year for 50 users, so it's not as compelling if your goal is strictly free. MoodleCloud MoodleCloud
• Canvas — I wouldn't choose it for this requirement right now. Although it historically had a free teacher offering, Instructure announced in June 2026 that Free-for-Teacher was permanently discontinued. Instructure

My recommendation

If you're building something like “a free learning community where volunteers answer questions, share lessons, and moderate members,” choose Discourse.

If you're building “an actual online school with courses, quizzes, assignments, and grades,” choose self-hosted Moodle.

The important distinction is that Discourse is community-first; Moodle is course/LMS-first. Both can avoid per-student platform fees, but Discourse's new free hosted tier is substantially easier for volunteer admins because you don't have to maintain a server. Discourse - Civilized Discussion

For a community-run education project with volunteer admins, I’d look first at Discourse.

One caveat

If you need a full learning-management system—courses, quizzes, assignments, grading, certificates, etc.—rather than primarily a community/discussion space, Moodle is a better fit. Moodle LMS is free/open-source when self-hosted, while MoodleCloud charges based on users/storage. moodlecloud.com support.moodle.com

My pick: Discourse for a volunteer-run learning community; self-hosted Moodle if the actual delivery of structured courses is the priority.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

• Good fit for volunteers: Moderation is built into the platform rather than requiring a separate moderation service. The main Free-plan limitation is 2 staff seats, so a larger admin team would eventually need a paid plan or self-hosting. Discourse - Civilized Discussion
• Education-specific alternative — moodle.org: Better if the project is primarily about structured courses, assignments, quizzes, grades, and learning management. Moodle is open-source with no licensing fees, but self-hosting/administration requires more technical work. Moodle Docs

My recommendation: Choose Discourse if the project is mainly a learning community (discussion, peer help, resources, announcements). Choose Moodle if it's mainly an actual school/course system.

If you tell me roughly how many learners and volunteers you expect, I can narrow this to the cheapest practical setup.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

Best fit: Discourse

discourse.org

The other big advantage is that Discourse is open source. If the project eventually needs more control, you can self-host it rather than being locked into the hosted service. Discourse - Civilized Discussion Discourse - Civilized Discussion

A few alternatives

• Moodle — better if the primary need is a full learning-management system (courses, assignments, grades, quizzes) rather than a community discussion space. It's open source, but hosting/admin work can be more involved.
• Discord — excellent for real-time volunteer/community communication and has substantial moderation functionality, but it's less suitable as a structured, searchable educational knowledge base.
• Circle — polished and education-friendly, but it doesn't fit your cost requirement as well: its current Professional plan is $89/month, and paid community transactions can also incur Circle fees. circle.so help.circle.so

My recommendation: If you're mainly building a place where learners, volunteers, and educators can ask questions, share resources, organize discussions, and moderate themselves, start with Discourse Free. Two volunteer staff seats should cover a small project, and trusted members can gradually take on community-moderation responsibilities.

For a community-run education project with volunteer admins, I’d shortlist these:

• discourse.org — best overall. Its new hosted Free plan is $0, supports unlimited members, includes 2 staff seats, and has built-in moderation such as flags/review queues, automated checks, and membership/permission controls. Discourse Discourse - Civilized Discussion
• flarum.org — best if you can self-host. It's free/open-source (MIT), lightweight, and includes groups/permissions plus built-in moderation and flagging. Your main cost is hosting rather than a platform fee. Flarum
• Self-hosted Discourse — best if avoiding any platform/vendor fee is the priority. The software is 100% free and open source, but you'll need to pay for or provide server hosting and have someone handle maintenance. Discourse - Civilized Discussion Discourse - Civilized Discussion

My pick

Start with the free hosted Discourse plan if your volunteers aren't particularly technical. You avoid platform fees, don't have to maintain a server, and get enough moderation functionality for a small-to-medium education community. The main limitation is 2 admin/moderator seats and 10 categories on the free tier. Discourse - Civilized Discussion

If you expect several volunteer moderators or want maximum control over the project and its data, self-hosted Flarum or Discourse is probably the better long-term choice.

For a volunteer-run education community, Discourse is probably the best fit if your priority is $0 platform cost + solid moderation + no per-admin fees.

• Discourse — Its new hosted Free plan is $0 forever, with unlimited members, unlimited chat, and 2 staff seats for admins/moderators. It includes flagging/review queues, automated content checks, membership controls, permissions, and trust levels. Discourse Discourse - Civilized Discussion
• Self-hosted Discourse — If someone on the project can manage a server, Discourse itself is open-source and free; you only pay hosting, potentially around $10–$100/month depending on infrastructure. Discourse - Civilized Discussion
• Discord — Free and excellent for live volunteer/student interaction, but moderation and file/history limitations can make it less suitable as a durable educational knowledge base. Discourse - Civilized Discussion
• Circle — More polished for courses/community-building, but its current paid plans start at $89/month and include transaction fees, so it doesn't match your “avoid platform fees” goal as well. Circle

My pick: Discourse Free if you're primarily organizing lessons, Q&A, resources, announcements, and volunteer discussions. It gives volunteers proper moderation tools without charging for each moderator, which is particularly useful for a community project. Discourse - Civilized Discussion

discourse.org

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

Best fit: Discourse

Discourse now has a $0 hosted plan with:

• Unlimited members
• Unlimited chat and discussions
• 2 staff seats for admins/moderators
• Built-in moderation tools: flags, review queue, automated checks, and membership/permission controls
• Trust levels that can give established community members additional moderation abilities
• Automatic updates and backups, so volunteers don't have to maintain a server
• No transaction/platform fee because it's primarily a discussion/community platform rather than a course marketplace. Discourse Discourse - Civilized Discussion

discourse.org

The main catch is that the free hosted plan gives you only 2 staff seats, and you're limited to 10 categories and 5 GB of storage. Discourse - Civilized Discussion

If you need actual courses

Moodle is better if you need lessons, assignments, quizzes, grading, learner enrollment, etc. But hosted MoodleCloud isn't free beyond its trial—the current entry plan is $170/year for 50 users. MoodleCloud

moodlecloud.com

You can also self-host Discourse or Moodle, avoiding platform fees entirely, but then your volunteers have to handle hosting, updates, backups, and security.

My recommendation: If the project is primarily peer learning + discussion + resource sharing, choose Discourse Free. If it's a structured online school/LMS, choose self-hosted Moodle if you have someone technically comfortable maintaining it.

For a community-run education project with volunteer admins, I’d prioritize platforms that have:

• No per-user fees or transaction/platform cuts
• Role-based moderation (admins, moderators, trusted users)
• Low maintenance for volunteers
• Data ownership/export options

Good options:

My shortlist for a volunteer-run education project

1. Moodle — best overall if you need actual courses

• Courses, lessons, quizzes, certificates, assignments
• Multiple admin/moderator roles
• No platform fee because you control the installation
• Main downside: needs someone to handle hosting/updates. Gibbon
• Discourse — best if the project is community-first

• Learners help each other through discussions
• Mature moderation tools
• Works well with volunteer moderators
• Less suited for formal coursework unless paired with another LMS
• Gibbon — good middle ground for small education communities

• Designed as a free, flexible school platform
• Open source with configurable user roles and permissions
• Easier than many enterprise LMS options for smaller groups. Gibbon
• Self-hosted WordPress + LMS plugin — easiest if your volunteers already know WordPress

• Fast to launch
• Lots of community tools
• Requires careful plugin selection to avoid maintenance headaches

Lowest-cost setup I’d choose

• Moodle for lessons and learner progress
• Discourse (or a chat platform) for peer discussion and moderation
• A cheap VPS (~$5–15/month) or nonprofit hosting if available

If the project is mostly volunteer teaching + discussion, choose Discourse.
If it is structured classes with modules and assessments, choose Moodle.
If it is a small community school/club, consider Gibbon. Gibbon

Avoid platforms that charge per student, take payment processing cuts, or lock moderation tools behind paid tiers—those costs tend to grow quickly as a community grows.

For that use case, Discourse is probably the best fit.

• $0 hosted option: Discourse now offers a free hosted plan with unlimited members, unlimited chat, a *.discourse.group subdomain, and 2 staff seats for admins/moderators. Discourse Discourse - Civilized Discussion
• No platform transaction fees: It isn't a course marketplace taking a percentage of donations, memberships, or sales. You'd still have any separate payment-processing costs if you collect money.
• Good basic moderation: It includes flagging/review queues, automated checks, membership/permission controls, trust levels, and moderator/admin tools. Discourse - Civilized Discussion
• Good for volunteer teams: Two staff seats on the free tier can cover a small admin/moderator team. The main free-tier limitations are 10 categories, 5 GB storage, and no custom groups/private categories. Discourse - Civilized Discussion
• More control if you grow: Discourse is open-source and can be self-hosted, so you're not permanently locked into the hosted service. Discourse - Civilized Discussion

discourse.org

One caveat: Discourse is primarily a community/forum platform, not a full learning-management system. If you need structured courses, quizzes, assignments, grading, and student progress tracking, I'd look at Moodle instead.

If your project is mainly lessons + discussion + volunteers moderating a community, I'd lean toward Discourse for simplicity.

For a community-run education project with volunteer admins, the best choice depends on whether you need a course system, a discussion community, or a full learning hub. If your priorities are no platform fees + basic moderation, these are strong options:

My practical picks

• Best overall for a volunteer education nonprofit: Moodle

• No transaction fees.
• Volunteers can be assigned admin, teacher, and moderator roles.
• Supports lessons, quizzes, assignments, forums, and enrollment control.
• Main tradeoff: someone needs to manage hosting and updates.
• Best for a learning community (discussion-first): Discourse

• Strong moderation model: trusted users can help moderate as the community grows.
• Good for Q&A, study groups, mentor networks, and knowledge sharing.
• Main tradeoff: less of a traditional classroom LMS.
• Best "start today" option: Google Classroom

• Very low setup effort.
• Good if you have a few volunteer instructors.
• Less suited to a large public community.

I would generally avoid marketplace-style course platforms (for example, many creator course sites) if your goal is community ownership, because they often take revenue shares, limit customization, or push paid tiers.

A common low-cost setup is:

• Moodle for courses
• Discourse for discussion and peer support
• volunteer moderators with clear roles and community guidelines

For a very small project (under a few hundred learners), you could also start with Discord or Google Classroom and migrate later. Vronify.chat

If you tell me whether this is K–12, adult learning, tutoring, a nonprofit academy, or a skills community, I can narrow it to the best 2–3 choices.

For a community-run education project with volunteer admins, the best fit is usually a platform that has:

• no per-member/platform transaction fees
• admin roles and permissions
• basic moderation (approval, removing posts, banning users, reporting)
• low technical overhead

Good options:

A few newer community platforms may also work depending on your needs:

• Mizzen offers a free collaboration platform for education teams, with team management features. Mizzen Education
• CollabED is a free educator community platform, though it is more of an existing education network than a blank-slate platform you control. CollabED

My practical picks

• Need courses, assignments, quizzes, learner progress: Moodle
• Need a volunteer-moderated discussion community: Discourse
• Need the cheapest/simple setup: WordPress + a community plugin
• Need a no-maintenance option: Google Groups (but it feels less like a modern learning platform)

For a volunteer-admin project, I would generally avoid platforms that charge per active member or take a cut of payments, because community growth can make those costs unpredictable.

If you tell me whether the project is mainly courses, peer discussion, or live classes/events, I can narrow it down to 2–3 choices.

For a community-run education project with volunteer admins, I’d prioritize: no transaction/platform fees, easy moderation, low maintenance, and ownership of your community data. Good options:

My practical recommendations:

• Small volunteer education community (50–5,000 members): Discourse is probably the easiest. It avoids marketplace-style fees and gives volunteers solid moderation tools. blog.discourse.org
• You need lessons, quizzes, certificates, and student progress: Moodle.
• You want maximum ownership and no vendor lock-in: self-host an open-source option such as Moodle, Discourse, or Lemmy. join-lemmy.org
• You want a “community school” feel (courses + discussion + events): consider combining a free LMS with a community forum rather than relying on a creator platform that takes fees.

I would generally avoid platforms built around selling courses (for example, marketplace-style course hosts) if your goal is a nonprofit/community model, because they often introduce payment processing cuts, member limits, or feature gates.

A simple low-cost stack:

1. Moodle for course materials
2. Discourse for discussions and volunteer moderation
3. Matrix/Discord-style chat only if you need real-time conversation (chat is usually harder to archive and moderate)

If you tell me your approximate size (e.g., 20 learners vs 20,000), whether you need video courses, and whether volunteers can manage hosting, I can narrow this to 2–3 choices.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list if the priority is $0 platform fees + straightforward moderation.

Best fit: Discourse

• $0/month hosted free plan, with unlimited members and chat.
• Includes 2 staff seats for admins/moderators.
• Built-in moderation: flagging, review queues, automated content checks, and membership/permission controls.
• Trust levels let established community members gradually earn additional abilities.
• No per-member or transaction/platform fee.
• You get a free *.discourse.group address, so you don't initially need to pay for hosting or a domain. blog.discourse.org

For a volunteer-run project, that's particularly attractive because you don't have to maintain a server. If you eventually need more control, Discourse is also open source and can be self-hosted, so you're not locked into the hosted service. www.discourse.org

If you need a real LMS: Moodle

Moodle

Moodle is better if the project needs courses, assignments, quizzes, grading, enrollment, and structured learning, rather than primarily community discussion. The software itself is open source, so self-hosting can avoid platform fees, but you'll need hosting and someone capable of maintaining it.

MoodleCloud is easier but isn't free beyond its trial; current plans start at $170/year for 50 users. www.moodlecloud.com

My recommendation

Bottom line: If you're essentially creating a community where people teach, ask questions, share resources, and discuss lessons, I'd choose Discourse Free. If you're actually delivering formal courses, I'd choose Moodle instead.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

My recommendation: Discourse

Discourse's new free plan is genuinely $0, with unlimited members, two staff seats, built-in chat, searchable discussions, trust levels, and moderation tools including flags, a review queue, automated checks, and granular membership controls. www.discourse.orgwww.mightynetworks.com

That combination is particularly good for volunteers because you don't have to maintain a server or pay based on the number of members. The free hosted version is maintained and updated by Discourse. www.discourse.org

If the project eventually needs more control, Discourse is also open source and self-hostable, so you're not locked into the hosted service. github.com

One caveat: the free hosted plan has 2 staff seats. If you need a larger volunteer moderation team, you'd need to upgrade or consider self-hosting. www.discourse.org

I would not choose Mighty Networks if avoiding platform fees is a core requirement: its paid plans currently include transaction fees (2%, 1%, or 0.5%, depending on plan), in addition to the subscription. www.mightynetworks.com

Bottom line: For a volunteer-run educational community where discussion, Q&A, moderation, and low cost matter more than fancy course delivery, Discourse is probably the strongest fit.

For a community-run education project with volunteer admins, I’d pick Discourse if the main need is a community/forum rather than a full learning-management system.

Best fit: Discourse

discourse.org is currently $0, with:

• Unlimited members and chat
• 2 admin/moderator seats
• Built-in moderation tools: flags, review queue, automated content checks, membership/permission controls
• Trust levels that can give experienced members additional community responsibilities
• Automatic updates and backups on Discourse's hosting
• No per-member or transaction/platform fees
• A free yourname.discourse.group address Discourse - Civilized Discussion Discourse - Civilized Discussion

That makes it particularly attractive when volunteers are doing the moderation and you don't want the organization's budget eaten up by per-user charges.

There's also a 100% open-source self-hosted version, so if someone on the project can manage a small server, you can avoid the hosted-platform cost entirely and retain control of the data. GitHub Discourse - Civilized Discussion

If you need actual courses: Moodle

moodle.org is the better choice if the project needs structured courses, assignments, quizzes, grades, learner progress, etc. Moodle itself has no licensing fees and is open source, but you'll need to provide hosting/support yourself. Moodle Moodle Docs

My recommendation:

• Discussion, peer support, volunteer moderation → Discourse
• Structured teaching/coursework → Moodle
• Both → Moodle for courses + Discourse for the community

If "avoids platform fees" means absolutely no vendor taking a percentage of donations, memberships, or course payments, Discourse is especially compelling because its pricing isn't transaction-based. Discourse - Civilized Discussion

For a community-run education project with volunteer admins, I’d put Moodle at the top of the list—especially if avoiding platform fees is important.

Moodle itself is open-source and has no licensing fees; a self-hosted installation lets your project control the platform and data, with your main expenses being hosting and whoever handles maintenance. docs.moodle.org

My recommendation: Moodle

For volunteers, I'd choose between:

• Moodle self-hosted — cheapest long-term and gives you maximum control. You can run it on inexpensive hosting, but someone needs to handle updates, backups and security. support.moodle.com
• MoodleCloud — easier for a volunteer team because Moodle handles hosting and updates. Current plans start at AUD $170/year for 50 users, with larger tiers available; there's also a 28-day trial. docs.moodle.orgsupport.moodle.comwww.moodlecloud.com

Moodle also has built-in roles, permissions, forums and collaborative tools, so you can give volunteer moderators limited administrative powers rather than handing everyone full-site access. docs.moodle.org

One caveat: if by "avoids platform fees" you mean you want to charge students for courses, distinguish between platform fees and payment-processor fees. A self-hosted Moodle site can avoid a percentage-of-sales platform charge, but Stripe/PayPal or another payment processor can still charge transaction fees.

If you tell me roughly how many learners/admins you expect and whether courses are free or paid, I can narrow this to the cheapest practical setup.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

• Discourse — best overall: Its current hosted Free plan is $0, with unlimited members and chat, 2 staff seats, and a free discourse.group subdomain. It includes flagging/review queues, automated moderation checks, membership/permission controls, trust levels, and admin tools. blog.discourse.org
• No transaction/platform fees: It isn't a course marketplace taking a percentage of donations or course sales. If you self-host, Discourse itself is free/open-source; you'd only pay your server/hosting costs. www.discourse.org
• Good for volunteers: The trust-level system lets established members take on more community-maintenance abilities, reducing the workload on a small admin team. discourse.org
• Main limitation: the free hosted plan has only 2 staff seats and 10 categories, so it works best if you have a small core admin/mod team. www.discourse.orgcommunity.instructure.com

If you need actual courses/classes

If the project needs lessons, assignments, quizzes, grading, and teacher/student roles, look at Moodle or Canvas Free-for-Teacher instead. Canvas currently offers an always-free teacher account, although its free version has restrictions on administrative/support features. community.instructure.com

My pick:
Discourse if this is primarily a learning community (discussion, resources, peer support, volunteer moderation).
Moodle if it's primarily a learning management system (structured courses and coursework).

If you tell me whether you need courses/assignments or mainly discussion + resource sharing, I can narrow it to 2–3 options with their actual costs and limitations.

For a community-run education project with volunteer admins, I’d pick Discourse if the main need is a community/forum rather than a full course-management system.

• $0 hosted plan: unlimited members and chat, with 2 staff seats for admins/moderators. www.discourse.org
• No transaction/platform fees: it isn't based on taking a percentage of donations, memberships, or activity.
• Basic moderation is built in: flags, review queues, automated content checks, membership controls, permissions, and trust levels. www.discourse.org
• Volunteer-friendly: Discourse handles hosting, updates, and backups on the free hosted plan, so volunteers don't need to maintain a server. www.discourse.org
• More control later: Discourse is open source, so you can self-host it and avoid hosted-platform costs if you eventually have someone who can manage infrastructure. www.discourse.org

One caveat: Discourse is primarily a community/discussion platform. If you need quizzes, graded assignments, structured courses, and learner progress tracking, Moodle is a better educational fit—but hosted MoodleCloud starts at about $170/year for 50 users, while self-hosting Moodle can be free software but requires technical administration. www.moodlecloud.com

Bottom line:
Discourse Free → best for a volunteer-run learning community, discussion, resources, Q&A, and basic moderation.
Self-hosted Moodle → best if the project genuinely needs an LMS and has technical volunteers.

For a community-run education project with volunteer admins, I’d pick Discourse if your main need is discussion, Q&A, announcements, and community moderation.

• $0 hosted option: Discourse currently offers a free hosted plan with unlimited members and chat, plus 2 staff seats for admins/moderators. blog.discourse.orgwww.discourse.orgmoodle.com
• No platform transaction fees: It isn't built around taking a cut of donations, memberships, or course sales.
• Good moderation: Flagging, review queues, automated checks, permissions, trust levels, and moderator tools are built in. www.discourse.org
• Good for volunteers: Hosting, updates, and backups are handled for you on the free hosted plan, so volunteers don't need to maintain a server. blog.discourse.org
• Open source: If you eventually want maximum control, Discourse can also be self-hosted for free; you'd just pay the server/hosting costs. www.discourse.org

One caveat: Discourse is primarily a community platform, not a full learning-management system. If you need structured courses, quizzes, assignments, grades, and learner progress, Moodle is the stronger free/open-source choice. Moodle itself is free to download and self-host, though hosting and administration aren't necessarily free. moodle.com

Bottom line:
Discourse → best for a low-maintenance, volunteer-moderated educational community.
Moodle → best if you're actually delivering structured courses.

If you tell me whether you need courses/lessons or mainly discussion + resource sharing, I can narrow it down to 2–3 options.

For that use case, Discourse is probably the best fit.

• $0 hosted option: Discourse now offers a free plan with unlimited members, unlimited chat, and 2 staff seats for admins/moderators. www.discourse.org
• No platform/transaction fees: It isn't a course-selling marketplace taking a percentage of payments. If you later sell things, normal payment-processor fees would still apply.
• Good moderation: Built-in flags, review queues, automated content checks, permissions, trust levels, post approval, and moderator tools are available. www.discourse.org
• Good for volunteer admins: The hosted free plan means volunteers don't have to maintain a server, backups, or updates.
• Open source: If you eventually want maximum control, Discourse is 100% open source and can be self-hosted. www.discourse.org

Discourse Free Plan

One caveat: Discourse is primarily a community/forum platform, not a full learning-management system. If you need structured courses, quizzes, grades, assignments, or learner tracking, Moodle is more appropriate, but its hosted MoodleCloud plans start around $170/year and scale with users. www.moodlecloud.com

So I'd choose:

Community discussion + volunteer moderation → Discourse
Actual structured online courses → Moodle
Lowest possible cost + maximum ownership → self-hosted Discourse www.discourse.org

If you tell me whether the project needs courses/lessons, live classes, file sharing, or just a community for learners, I can narrow it to 2–3 options.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

Best fit: Discourse

Discourse Free Plan

• $0 hosted plan with unlimited members and unlimited chat. www.discourse.org
• No platform transaction fees because it isn't built around selling courses or memberships.
• Basic-to-strong moderation: flags, review queues, automated content checks, trust levels, and granular membership controls. www.discourse.orgwww.moodlecloud.com
• Only two staff seats on the free hosted plan, which could matter if you have several volunteer moderators. www.discourse.orgwww.moodlecloud.com
• It's also open source, so you can self-host it if you want maximum control and are willing to handle hosting/maintenance. www.discourse.org

If you need actual courses: Moodle

MoodleCloud

Moodle is better if the project needs structured courses, assignments, quizzes, grades, and learner enrollment. However, its hosted MoodleCloud option isn't free beyond a 28-day trial; current plans start around US$170/year for 50 users (billed in AUD), so it doesn't fit the "zero-cost" requirement as well. www.moodlecloud.com

You can also self-host Moodle, avoiding a platform fee, but that shifts the burden of server administration to the volunteers.

My recommendation:

• Discussion/community + shared learning resources → Discourse
• Formal online courses/classes → Moodle
• Want $0 and minimal technical work → Discourse's free hosted plan

If you tell me whether you need course lessons/quizzes or mainly discussion + resource sharing, I can narrow it to 2–3 options with their actual costs and moderation capabilities.

For a volunteer-run community education project, Discourse is probably the best fit right now.

• $0 hosted option: Discourse's new Free plan includes unlimited members, unlimited chat, a free discourse.group subdomain, and 2 staff seats for admins/moderators. blog.discourse.orgwww.discourse.org
• Basic moderation: flagging, review queues, automated checks, trust levels, and granular membership/permission controls are included. blog.discourse.orgwww.discourse.org
• No platform transaction fees: it's a community/forum platform rather than a course marketplace taking a cut of payments.
• No per-member pricing: if you outgrow the free hosted tier, paid Discourse plans are flat-rate rather than charging per member. www.discourse.org
• Maximum cost control: Discourse is open source, so you can self-host it and pay only for inexpensive server hosting. www.discourse.org

Discourse Free Plan

One caveat: if the project needs actual structured courses—lessons, assignments, quizzes, grading, etc.—I'd choose Moodle instead. Moodle is free/open-source with no licensing fees, but self-hosting requires more technical administration. docs.moodle.org

My pick: Discourse for a community centered on discussion, peer learning, resources, and volunteer moderation; Moodle if the core product is courses and coursework.

For a community-run education project with volunteer admins, I’d put Discourse at the top of the list.

Best fit: Discourse

Discourse Free Plan

• $0 hosting plan with unlimited members and chat.
• No transaction/platform fees—it isn't a paid-course marketplace taking a cut of donations or memberships.
• Basic moderation is built in: flags, review queue, permissions, trust levels, and spam/content checks. blog.discourse.org
• Two staff seats on the free plan, which is useful for a small volunteer admin team. www.discourse.org
• Good for education because discussions are organized into searchable topics rather than disappearing into a social-media feed.
• It's also open source, so if you eventually want complete control, you can self-host it instead. www.discourse.org

One caveat: the free hosted version has some limits (including categories and customization), so it's best for a discussion/community hub rather than a sophisticated LMS.

If you want maximum control: Lemmy

Lemmy

Lemmy is free/open source, self-hostable, decentralized, and has strong moderation tools. join-lemmy.org It's attractive if the project has someone technically comfortable maintaining a server, but I'd choose Discourse for volunteer admins who don't want to become sysadmins.

Bottom line: Discourse Free is probably the sweet spot: $0, no platform cut, straightforward moderation, and very little technical overhead.

For a volunteer-run community education project, Discourse is probably the best fit if your main needs are community discussion, announcements, Q&A, and basic moderation.

Best options

Why I'd pick Discourse: its current free plan has unlimited members, 10 categories, 5 GB storage, two staff seats, built-in moderation/review tools, trust levels, and unlimited chat. www.discourse.org

It also doesn't charge a percentage of donations, memberships, or other community activity—it's a hosted community platform rather than a marketplace. If you eventually need more control, Discourse is open-source and can be self-hosted, so you aren't locked into the hosted service. www.discourse.org

One caveat: if by "education project" you mean structured courses with assignments, grading, quizzes, certificates, and learner progress tracking, I'd choose Moodle instead. Moodle itself is free/open-source, while its managed MoodleCloud service is paid. www.moodlecloud.com

Bottom line:

• Community + volunteer moderation → Discourse
• Courses + assignments/grades → Moodle
• Want both → Moodle for coursework + Discourse for the community

If you tell me roughly how many learners/admins you expect and whether you need actual courses or mostly discussion, I can narrow it down to the cheapest practical setup.

For a volunteer-run education community, I’d put Discourse at the top of the list.

My recommendation: Discourse

Discourse now has a free-forever hosted plan with unlimited members, unlimited chat, and two staff seats for admins/moderators. It includes flags, a moderation review queue, automated checks, membership controls, permissions, trust levels, and search. blog.discourse.orgjoin-lemmy.org

That combination is particularly attractive for a community where volunteers are doing the administration: you don't have to maintain a server, and there isn't a platform fee eating into donations or membership revenue.

It also remains open source, so if the project eventually needs more control, you can self-host it rather than being locked into the hosted service. www.discourse.org

One limitation: the free hosted plan only gives you two staff seats. If you need a larger volunteer moderation team, you'd need to upgrade or self-host. www.discourse.org

If independence matters most

Lemmy is worth considering. It's open source, self-hostable, has transparent moderation logs, and has no advertising or user-tracking business model. The tradeoff is that it's more technically oriented and you'll need someone willing to operate the server. join-lemmy.org

I would not choose Mighty Networks if "avoid platform fees" is a hard requirement: its paid plans charge transaction fees when you process payments through the platform. docs.mightynetworks.com

Bottom line: for a small education project with volunteer admins, Discourse Free is probably the sweet spot—$0 hosting, basic-to-good moderation, unlimited members, and very little technical overhead.

For a community-run education project with volunteer admins, I’d shortlist these:

My pick: Discourse

For your specific requirements, Discourse is probably the best fit. Its new free hosted plan is genuinely $0, supports unlimited members, includes two staff/admin seats, and provides built-in moderation tools such as flags, a review queue, and granular membership/permission controls. blog.discourse.org

It also doesn't take a percentage of donations, course fees, or community activity because it isn't a transaction marketplace. If you self-host it, the software itself is free and open source; you'd only pay for server hosting. www.discourse.org

The main limitation is that Discourse is primarily a community/forum platform, not a full LMS. If you need structured courses, quizzes, assignments, grades, or certificates, Moodle is the stronger choice. Moodle LMS itself is free/open source, while MoodleCloud provides managed hosting at a relatively low annual cost. www.moodlecloud.com

Rule of thumb:

• Community + discussions + volunteer moderation → Discourse
• Courses + assignments + assessments → Moodle
• Want both → Moodle for coursework + Discourse for the community layer

If "avoids platform fees" means you also need to collect paid course/donation payments, that's a slightly different comparison because payment processors can still charge transaction fees even when the platform doesn't.
