For a freelance trainer selling memberships, hosting discussions, and running events, I’d narrow it to a few platforms rather than a huge list. The best choice depends on whether you’re selling access to you, a learning program, or a professional network. Mighty Networks Mighty Networks

My shortlist

Mighty Networks Mighty Networks## What I’d pick for different trainer models

1. You run live cohorts, workshops, and ongoing memberships

Pick: Circle

Example:

• $49/month membership
• Weekly Q&A call
• Discussion spaces (“Ask a Coach,” “Wins,” “Resources”)
• Monthly workshops
• Member directory

Circle is probably the closest match to a modern professional training community. Mighty Networks

2. You want members networking with each other

Pick: Mighty Networks

Good for:

• Leadership communities
• Fitness/wellness groups
• Career coaching
• Entrepreneur communities

Its design emphasizes member profiles, interaction, events, and community engagement. Mighty Networks

3. You sell premium programs ($500–$5,000+)

Pick: Kajabi

Good stack:

• Free webinar → email funnel → paid course → coaching upsell
• Membership library
• Automated marketing

Kajabi shines when selling is as important as community. Digital Course Freelancer

4. You’re testing your first paid group

Pick: Skool

Useful if your offer is:

• “Join my 8-week transformation”
• “Weekly accountability group”
• “Mastermind”

It’s intentionally simple. Mighty Networks

My recommendation for most freelance trainers

I’d start with:

1. Circle → if your brand is professional training/coaching
2. Mighty Networks → if your goal is building a long-term member community
3. Kajabi → if you already have courses and a sales funnel

A good early setup:

• Free newsletter/community preview
• Paid membership tier ($29–99/month)
• Monthly live event
• Weekly discussion prompt
• Member directory
• Premium coaching upsell

A few questions would change the recommendation:

1. What kind of trainer are you (fitness, corporate, career, skills, leadership, etc.)?
2. Do you already have an audience/email list?
3. Are you selling mainly monthly memberships or one-time courses/coaching packages?

For a freelance trainer, I’d choose based on what you’re selling: a community membership, a training program, or a coaching ecosystem. The best platform is usually the one that matches your business model, not the one with the most features. Mighty Networks

Here are the strongest options:

My recommendation by trainer type

1. You run live workshops, cohorts, and discussion-based learning
→ Circle
Best fit if your value is interaction: weekly calls, Q&A, peer discussion, accountability groups.

2. You want a “professional academy” feel
→ Mighty Networks
Good for building a member network where people connect with each other, not just consume your content. Mighty Networks

3. You sell premium training packages ($500–$5,000+)
→ Kajabi
Useful if your business depends on marketing funnels, email campaigns, and selling multiple offers. Mighty Networks

4. You are starting with one coaching program
→ Skool or Circle
Keep it simple until you have enough members to justify a bigger stack. Creator Economy

A typical setup I’d suggest for a freelance trainer

• Free lead magnet → email list
• Paid membership ($29–$99/month)
• Weekly live training session
• Discussion area for questions and wins
• Monthly guest event/masterclass
• Premium tier for 1:1 coaching or small groups

For most independent trainers, I’d narrow it to:

1. Circle — best overall balance
2. Mighty Networks — best if community/networking is the product
3. Kajabi — best if marketing and course sales are the priority

If you tell me your niche (fitness, corporate training, language, leadership, tech skills, etc.), your expected member count, and whether you already have courses/videos, I can narrow it down further.

2. You want a “professional academy” feel
→ Mighty Networks
Good for building a member network where people connect with each other, not just consume your content. Mighty Networks

3. You sell premium training packages ($500–$5,000+)
→ Kajabi
Useful if your business depends on marketing funnels, email campaigns, and selling multiple offers.

For a freelance trainer selling memberships, I’d narrow it to Circle, Mighty Networks, and Skool. The best choice depends on whether your business is primarily community, events, or coaching/accountability.

My pick: Circle

circle.so is probably the best fit if you want a professional, premium-feeling membership business.

Why I'd choose Circle for you

If your offer is something like:

$29–$99/month membership → training content + member discussion + weekly live sessions + workshops/events

Circle gives you a clean place to put all of that together. Recent comparisons also put Circle among the strongest options for creator memberships, particularly when you want community, courses and events in one experience. LinoDash AITechStack

Mighty Networks is the one I'd seriously consider instead. It is particularly strong if you want the community itself to feel like the product—member profiles, feeds, groups, gamification, courses and events are deeply integrated. Its current Launch plan is $79/month, with unlimited members and spaces, courses and events. Mighty Networks

mightynetworks.com

Skool makes sense if you're running a straightforward coaching/accountability membership where points, leaderboards and a simple community feed help keep people engaged. It's less attractive if you want a highly branded or sophisticated member experience.

The decision I'd make

• You want a polished professional membership: Circle
• You want members interacting with each other heavily: Mighty Networks
• You want simple coaching + accountability + gamification: Skool
• You want a course business with funnels/email/marketing at the center: Kajabi

For a freelance trainer specifically, I'd start with Circle unless your main selling point is the community itself—in that case, Mighty Networks.

If you tell me what you train people in, your expected membership price, and roughly how many members you expect in year 1, I can recommend the exact platform/plan and show you how I'd structure the membership.

If your offer is something like:

$29–$99/month membership → training content + member discussion + weekly live sessions + workshops/events

Circle gives you a clean place to put all of that together. Recent comparisons also put Circle among the strongest options for creator memberships, particularly when you want community, courses and events in one experience. linodash.com aitechstack.io

Mighty Networks is the one I'd seriously consider instead. It is particularly strong if you want the community itself to feel like the product—member profiles, feeds, groups, gamification, courses and events are deeply integrated. Its current Launch plan is $79/month, with unlimited members and spaces, courses and events.

For a freelance trainer selling memberships, where you want paid access + discussion + recurring events in one place, I’d shortlist Circle, Mighty Networks, and Skool.

My pick: Circle

Circle is probably the best fit if you want your business to feel professional and flexible, rather than like a generic Facebook group.

It gives you:

• Paid memberships/subscriptions
• Discussion spaces and member profiles
• Events, live streams and live rooms
• Courses/content
• Different membership tiers and access controls
• Website/landing pages
• Automations and analytics

Circle's current Professional plan is listed at $89/month, with unlimited members and the core community, events, courses, memberships and live features. circle.so

The alternatives

Mighty Networks is particularly strong if community interaction is the product. It combines discussions, chat, courses, livestreams and events, including paid events and recurring events. www.mightynetworks.com

Kajabi is the one I'd consider if your business is primarily selling structured training programs, with community being an add-on. Its strength is more on the course/content + marketing side than community-first interaction. www.mightynetworks.com

What I'd do in your shoes

If you're offering something like:

$49/month — weekly training + monthly workshop + member community + Q&A

I'd use Circle.

You could structure it as:

Community

• Announcements
• Member introductions
• General discussion
• Wins/results
• Questions & support

Training

• Your training library
• Resources
• Recordings

Events

• Weekly group training
• Monthly masterclass
• Office hours/Q&A
• Guest sessions

Membership

• Free → paid conversion
• Monthly membership
• Premium/1:1 tier

That gives you one place for the sale → onboarding → training → discussion → event → retention loop, rather than stitching together Zoom + Stripe + Facebook/Discord + course software.

If you tell me what kind of training you do, your expected membership price, and roughly how many members you expect in year 1, I can tell you whether I'd choose Circle vs Mighty vs Skool specifically for your business and what I'd charge.

For a freelance trainer selling memberships, I’d shortlist Circle, Mighty Networks, and Skool. Your combination of paid memberships + discussion + live events makes a community-first platform a better fit than a pure course platform.

My pick: Circle

Circle is probably the best overall fit if you want your business to feel professional and premium.

• Memberships: subscriptions, paywalls, multiple access levels
• Discussion: excellent space-based discussions, chat, member profiles
• Events: built-in events, live streams and live rooms
• Training: courses can live alongside the community
• Branding: custom domain and branding
• Current Professional price: $89/month, with unlimited members; Business is $199/month. circle.so

For a trainer, I could see a structure like:

$49/mo — Training Community
Weekly group workout/coaching session + discussion + monthly workshop

$99/mo — Premium
Everything above + additional live sessions + small-group coaching

$299/mo — VIP
Everything + 1:1 coaching

That maps very naturally onto Circle's spaces, memberships and events.

Runner-up: Mighty Networks

Mighty Networks is the one I'd choose if you want the community to feel more like a social network/mobile app.

It has memberships, discussion/activity feeds, courses, events, livestreaming, gamification and native mobile apps. Its current Launch plan is $79/month, while Scale is $179/month. www.mightynetworks.com

Choose Mighty over Circle if: member-to-member interaction and mobile engagement are central to your offer.

Budget/simple option: Skool

Skool is attractive if your priority is "make this incredibly simple." Its strength is a straightforward community + course + gamification model, rather than lots of customization. Current comparisons put it at $9/month plus a 10% transaction fee. www.mightynetworks.com

Choose Skool if: you're selling a relatively simple coaching/training membership and don't care much about sophisticated branding.

What I'd do in your shoes

My recommendation: start with Circle. It gives you the cleanest combination of selling recurring memberships, running conversations, hosting live training/events, and eventually adding courses without making the community feel like an afterthought. Circle explicitly positions its platform around community, courses, events and revenue in one place. circle.so

If you tell me what kind of training you do, your expected membership price, and roughly how many members you're aiming for, I can narrow it down to the best platform and tell you exactly how I'd structure the membership/community.

If you're a freelance trainer and want one platform to sell memberships + host discussion + run events, I'd shortlist Circle, Mighty Networks, and Skool.

My pick: Circle

Circle is probably the best fit if you want your business to feel professional and trainer-led, rather than like a social-media group.

Circle currently includes discussions, paid memberships, courses, events, live streams/rooms, member profiles, website building, payments, and analytics in its Professional plan at $89/month. circle.so

When I'd choose the others

Mighty Networks — choose this if the community itself is your product. It has courses, events, livestreaming, gamification, and strong mobile/community functionality. Its current Launch plan is $79/month monthly. www.mightynetworks.com

Mighty Networks

Skool — choose this if you want something extremely simple: membership → community → course → live calls. Its current pricing starts at $9/month, with a 10% transaction fee on the Hobby plan; Pro is $99/month with a 2.9% transaction fee. www.skool.com

Skool

What I'd do in your shoes

If you're selling something like:

$49–$149/month membership
weekly training/Q&A
member discussion
monthly workshops
occasional guest experts
resource library

I'd go Circle.

It gives you enough structure to make the membership feel like a real training business, without forcing you into a full-blown course/marketing platform. Circle also specifically supports paid memberships and events alongside discussion and live sessions. circle.so

If your offer is more like "join my group, get accountability, attend my weekly calls, and interact with other members", I'd lean Skool.

If it's "the network/community is the main product", I'd lean Mighty Networks.

If you tell me what you train people in, your expected membership price, and roughly how many members you expect in year 1, I can narrow it down to one platform and show you what your setup should look like.

If you’re a freelance trainer selling a recurring membership, hosting discussions, and running live events, I’d narrow it to Circle vs. Mighty Networks vs. Skool.

My pick: Circle

Circle is probably the best fit if you want a professional training community that can grow into a real business.

Why I'd choose Circle for you: it combines paid memberships, subscriptions, discussions, courses, live streams, events, member profiles, and website/landing-page functionality in one platform. Its current Professional plan is $89/month. circle.so

The big advantage for a trainer is that you can structure it something like:

Your Membership

• 📚 Training library
• 💬 Community discussion
• 🗓️ Weekly live training
• 🎤 Monthly expert event
• 👥 Member-only groups
• 🎯 Challenges/accountability
• 💳 Monthly + annual membership tiers

When I'd pick Mighty instead

Mighty Networks is excellent if community interaction is the product, rather than training content being the product. It has feeds, chat, events, livestreaming, courses, paid events, gamification, and native mobile apps. www.mightynetworks.com

I'd choose Mighty if your vision is more like:

"Join my community, meet other professionals, attend weekly events, participate in challenges, and learn from each other."

When I'd pick Skool

Skool makes sense if you want something very simple and low-friction, particularly for coaching/accountability communities. Its big differentiator is the community + gamification model. But if events and a polished training experience are central to your offer, I'd put Circle ahead of it.

My recommendation for a freelance trainer

Start with Circle unless you specifically want a highly social, mobile-first community—in which case choose Mighty.

I'd also avoid building a Frankenstein stack of Zoom + Discord + Stripe + Eventbrite + Teachable + email software at the beginning. The value of these platforms is that your member sees one place to pay → learn → discuss → attend events.

If you tell me what kind of training you do, your expected membership price (e.g. $29/$99/$299 per month), and roughly how many members you expect, I can tell you which platform I'd use and how I'd structure the membership.

For a freelance trainer who wants to sell memberships + host discussions + run events, I’d shortlist Circle, Mighty Networks, and Skool.

My pick: Circle

Circle is probably the best fit if you want your business to feel professional and branded, rather than like a generic Facebook group.

Its Professional plan is currently $89/month and includes unlimited members, paid memberships, discussions, courses, events, live streams/rooms, custom branding, a website builder, and analytics. circle.so

Why I'd choose it for you:

• 💳 Sell recurring memberships
• 💬 Organize discussions into different spaces/topics
• 📅 Run live and in-person events
• 🎥 Host courses/training
• 🔴 Run live sessions and Q&As
• 🌐 Give members a branded home for your business
• 📈 Better long-term flexibility if your training business grows

The alternatives

Mighty Networks is especially compelling if you want members interacting with one another frequently. It combines memberships, courses, events, livestreaming and community, with plans currently starting at $79/month monthly. www.mightynetworks.com

Kajabi is more of an all-in-one business platform: its strength is marketing, email, landing pages, funnels, courses and memberships. But at $143/month billed annually for Basic, I'd find it harder to justify if your primary need is community + events. www.kajabi.com

What I'd do in your shoes

If you're selling something like:

$49–$149/month membership → weekly training → monthly workshop → member discussion → occasional 1:1/coaching upsells

I'd start with Circle.

You can structure it as:

🏠 Community

• Announcements
• Introductions
• General discussion
• Wins/accountability

🎓 Training

• Training library
• Courses/programs
• Resources

📅 Events

• Weekly group training
• Monthly masterclass
• Guest sessions
• Event replays

💰 Membership

• Free/lead-generation area
• Paid membership
• Premium coaching tier

That gives you one place for the sale → onboarding → training → community → events → retention, instead of stitching together Zoom + Facebook/Discord + Stripe + an LMS.

If you tell me what kind of trainer you are (fitness, corporate, sales, personal development, technical, etc.) and roughly how many members you expect, I can tell you which platform I'd actually pick and what membership structure I'd use.

For a freelance trainer selling memberships + running discussions + hosting events, I’d shortlist Circle, Mighty Networks, and Skool. My default recommendation is Circle.

🥇 My pick: Circle

Circle is particularly well matched to a freelance trainer because you can structure your business into membership spaces, discussion groups, courses, workshops, and events without sending members to several different services. It supports paid memberships/subscriptions, discussions, events, live streams, courses, and a member directory. Its Professional plan is currently $89/month. circle.so

For example, you could build:

• Community — general member discussion
• Training Hub — your recorded programs/resources
• Weekly Q&A — member questions and coaching
• Live Workshops — monthly paid/free events
• Challenges — 30-day training challenges
• VIP Membership — higher-priced access to you
• Events Calendar — upcoming workshops and sessions

That's a very clean model for turning freelance training into recurring revenue.

🥈 Mighty Networks

I'd choose Mighty if your business is less "course platform" and more "club/community that happens to have training."

It has discussions, chat, events, paid events, courses, livestreaming, gamification and native mobile apps. Its community features are particularly focused on getting members interacting with each other rather than just consuming your content. circle.sowww.mightynetworks.comcircle.so

🥉 Skool

Skool is attractive if your training is built around accountability, cohorts, challenges and participation. Its big advantage is simplicity; you don't need to spend much time designing a complicated community.

I'd pick it over Circle if your proposition is something like:

"Join my 12-week fitness/business/sales training community, complete the weekly challenges, earn points, attend my calls, and interact with other members."

For a more polished professional training brand, though, I'd lean Circle.

What I'd do in your position

If you're starting from scratch, I'd avoid building a stack of five different tools.

I'd start with Circle + Stripe and sell something like:

$39–79/month membership
→ community
→ weekly discussion/Q&A
→ monthly live workshop
→ resource library
→ member-only events

Then add a $150–300/month premium tier for small-group coaching or live training.

Circle is particularly good for this because memberships, courses, events, payments and community can live together. circle.so

Bottom line:
Circle = best overall for a serious freelance training business.
Mighty = best if community/social interaction is the product.
Skool = best if accountability and simplicity are the product.
Kajabi = best if marketing funnels and courses matter more than community.

If you tell me what kind of training you do, your expected member price, and whether your events are online or in-person, I can narrow this down to the best platform and membership structure for you.

If you’re a freelance trainer and want one platform for paid memberships + discussion + events, I’d shortlist these three:

🥇 My pick: Mighty Networks

For a trainer, Mighty is particularly compelling because you can combine membership payments, discussion feeds, live events, courses, livestreaming, chat, and member profiles without stitching several services together. Its event system supports calendars, RSVPs, reminders, recurring events, and paid events. www.mightynetworks.com

It also has native iOS/Android apps, which is useful if you want members to actually use the community between training sessions. www.mightynetworks.com

Mighty Networks

When I'd choose the others

Circle — I'd choose this if you're selling a more premium/professional training experience and want very organized discussion spaces, content and events. It's particularly strong for a community-first membership business. www.digitalcoursefreelancer.com

Skool — I'd choose this if your training is heavily based on accountability, challenges, progress and peer interaction. It deliberately keeps things simple and combines communities, courses, events and paid subscriptions. www.skool.com

Skool

For your specific business

I'd structure it something like:

$49–99/month membership

• Weekly live training session
• Monthly workshop/masterclass
• Community discussion
• Member Q&A
• Challenges/accountability
• Resource library
• Occasional guest expert events

Then potentially a higher-priced coaching tier for 1:1 or small-group training.

If you're primarily selling your expertise through live training rather than selling courses, I'd lean Mighty Networks > Circle > Skool.

If you tell me what kind of trainer you are (fitness, corporate, sales, leadership, technical, etc.) and roughly how many members you expect, I can narrow it down to one and compare the current pricing + transaction fees + event capabilities.

For a freelance trainer selling memberships + hosting discussions + running live events, I’d shortlist Circle, Mighty Networks, and Skool.

My pick: Circle

Circle is probably the best fit if you want your business to feel professional and structured, rather than just like a chat group.

It gives you:

• Paid memberships/subscriptions
• Discussion spaces and chat
• Courses/content
• Live events, RSVPs and livestreams
• Member profiles/directories
• Website/landing pages
• Payments and access control
• Automations and analytics on higher plans

Circle's Professional plan is currently $89/month, with unlimited members, courses, discussions, events, live streams, paid memberships and a custom domain. circle.so

I'd choose Circle if: your training business is something like “$49–$199/month membership + weekly training + community + occasional workshops.”

The alternatives

Mighty Networks is particularly strong for a trainer who wants members interacting with one another. It combines community, courses, memberships, livestreams and events, and has native mobile apps. www.mightynetworks.com

Skool is worth considering if you want something extremely simple: community + content + membership + gamification, without building a complicated system. I'd favor it for an accountability/coaching group rather than a polished training academy.

Kajabi makes more sense if you're primarily selling courses and coaching and need sophisticated marketing funnels/email alongside the membership. www.digitalcoursefreelancer.com

For your specific use case

I'd rank them:

1. Circle — 9/10
Best balance of membership + discussion + training + events.

2. Mighty Networks — 8.5/10
Better if you want the community itself to be a major part of the value.

3. Skool — 8/10
Better if you want to launch quickly and keep everything very simple.

4. Kajabi — 7.5/10
Better if you're building a larger course/marketing business rather than primarily a community.

If you tell me what you train people on, your expected membership price (e.g. $29/$99/$199/mo), and roughly how many members you expect in year 1, I can narrow this down to the best platform and show you the actual monthly cost + transaction fees + what your member experience would look like.

For a freelance trainer selling a paid membership + discussion community + live events, I’d shortlist Circle, Mighty Networks, and Skool.

My pick: Circle

Circle is probably the best fit if you want your business to feel professional and structured, rather than like a generic social group.

Circle: Paid memberships, subscriptions, discussions, events, live streams, courses, website/landing pages, and payments are all built in. Its current Professional plan is listed at $89/month. circle.socircle.so

Mighty Networks: I'd choose this if the community itself is your product. It combines discussions, chat, events, livestreaming, courses, memberships and even native mobile apps. www.mightynetworks.comwww.skool.com

Skool: Very attractive if your model is basically "pay monthly → join my training → get accountability → attend group calls." It deliberately keeps things simple and combines community, courses, events and paid subscriptions. www.skool.com

What I'd do in your shoes

If you're selling something like:

$49–199/month → weekly training → community discussion → monthly workshops/events → access to you

I'd start with Circle.

You can structure it as:

🏠 Community

• Announcements
• Member introductions
• Q&A
• Wins/results
• General discussion

🎓 Training

• On-demand training
• Resources
• Programs/challenges

📅 Events

• Weekly group training
• Monthly masterclass
• Q&A sessions
• Guest sessions

💰 Membership

• Free community → paid membership
• Or multiple paid tiers
• Recurring subscriptions

Circle explicitly supports paid memberships, subscriptions, gated content, live streams, chat, messaging and events in the same platform. circle.socircle.so

One important distinction: if your competitive advantage is you and the community, rather than a huge library of courses, don't overcomplicate the setup. I'd favor Circle or Mighty over a traditional course platform.

If you tell me what you train people in, your expected membership price, and roughly how many members you expect in year 1, I can tell you which of the three I'd pick and how I'd structure the membership.

For a freelance trainer selling a paid membership with discussion + live events, I’d shortlist Circle, Mighty Networks, and Kajabi. My default pick for you would be Circle.

🥇 My pick: Circle

Circle is particularly well suited if your business is something like:

$49–$199/month membership → training content → discussion → weekly/monthly live sessions → ongoing coaching

It lets you create separate spaces for things like General Discussion, Training Library, Q&A, Challenges, and Events, while handling memberships, subscriptions, paywalls, live streams and chat in the same platform. circle.so

Circle membership platform

Why I'd choose it: it feels more like a professional membership community than a course platform. That's important for a trainer because the community and interaction can be part of what people are paying for—not just your videos.

🥈 Mighty Networks

I'd choose Mighty if you want the community itself to be the product.

It combines memberships, discussions, courses, events and livestreaming, with particularly strong community/engagement features and native mobile apps. www.mightynetworks.com

Mighty Networks

This is especially interesting if your membership revolves around weekly events, challenges, member interaction and accountability.

🥉 Kajabi

Choose Kajabi if you're really building a training business, rather than primarily a community.

It connects memberships directly with courses, offers, email marketing, payments and community access. It also has built-in Meetups for live virtual events. www.kajabi.com

Kajabi Communities

The downside is that you're paying for a much broader marketing/business system than you may actually need.

What I'd do in your shoes

If you're a solo freelance trainer, I'd start with:

Circle → paid membership → recurring monthly fee → discussion spaces → weekly group session → monthly workshop → resource library.

Don't overbuild it. Your value proposition should be something like:

"Join the community, get the training, ask questions, and show up every week."

That's a much stronger membership model than simply putting a library of videos behind a paywall.

If you tell me what kind of training you do, your target member, and roughly what you want to charge/month, I can narrow this down to the best platform + exact membership structure for your business.

For a freelance trainer selling a paid membership, with discussion + events + training content all under one roof, I’d shortlist Circle, Mighty Networks, and Kajabi.

My pick: Circle

Circle is probably the best fit if your business is trainer-led and community-driven.

It gives you:

• Paid memberships/subscriptions
• Discussion spaces, chat and member profiles
• Live events, livestreams and live rooms
• Courses/content
• Multiple membership tiers and gated spaces
• Website/landing pages and payments
• Automations and email tools on higher plans circle.so

The Professional plan is currently $89/month, with a 14-day trial. circle.so

Why I'd choose it for you: you can structure the business around something like:

$49/mo Membership → training library + private community + weekly group session
$149/mo Pro → everything above + monthly workshop + group coaching
$500+ Workshop → standalone intensive/event

That feels much more like a professional training business than simply putting people into a Facebook/Discord group.

The alternatives

Mighty Networks is particularly strong for events and member interaction. It combines discussions, chat, courses, livestreaming, events and memberships, and emphasizes member-to-member engagement. Its Launch plan is currently $79/month. circle.sowww.mightynetworks.comwww.kajabi.com

Kajabi makes more sense if you're building a course + marketing machine. Its Communities product supports paid/free access groups, discussions, memberships, and built-in virtual Meetups. www.kajabi.com

What I'd do in your shoes

Start with Circle unless your business is primarily:

• Courses + email funnels + marketing: Kajabi
• Social community + lots of member interaction/events: Mighty Networks
• Simple coaching/accountability + gamification: Skool
• Premium professional training community: Circle

One important point: don't choose based on feature count. For a freelance trainer, the real question is whether your members will have a compelling reason to come back every week. Circle's combination of discussion + events + content makes it particularly good for creating that recurring rhythm. circle.so

If you tell me what you train people on, your target monthly membership price, and roughly how many members you expect in year 1, I can recommend the exact platform + plan and sketch out how I'd structure your membership.
