Yes. For an agency developing custom WordPress/PHP plugins, I’d prioritize developer access + client isolation + white-label/reseller management, rather than traditional “cheap reseller hosting.”

My shortlist

1. Ultra Web Hosting — probably the closest match to what you're describing. Their reseller environment specifically advertises separate cPanel accounts per client, white-label nameservers/branding, Git Version Control, SSH, Composer, WP-CLI, staging, and multiple PHP versions. www.ultrawebhosting.com

Ultra Web Hosting agency/reseller hosting

2. InMotion Hosting — a more established conventional reseller option. SSH is available on reseller accounts, and their documentation confirms Composer support. They use WHM/cPanel, which is convenient if you want each client to have their own hosting account. www.inmotionhosting.com

InMotion Hosting reseller hosting

3. Cloudways — my choice if developer workflow matters more than traditional reseller hosting. It has SSH/SFTP, Git deployment, Composer, staging, application isolation, and agency-oriented client management. It also explicitly supports agencies reselling hosting. www.cloudways.com

Cloudways agency hosting

The important distinction is that Cloudways is more of a managed cloud/application platform than classic WHM reseller hosting. That's actually an advantage if your agency's developers will routinely SSH in, run Composer, deploy Git repositories, use WP-CLI, and maintain custom plugins.

What I'd choose

If your model is:

Build custom plugins → host client sites → maintain them → charge clients monthly hosting/maintenance

I'd pick Ultra Web Hosting if you specifically want a white-label reseller business, and Cloudways if your priority is the best developer experience.

For example, your workflow could be:

Local development → Git repository → staging client site → Composer/plugin deployment → production

That's substantially better than a reseller host that technically offers SSH but makes Git/Composer awkward or restricted.

If you tell me roughly how many client sites you expect (10 / 50 / 100+) and whether they're mostly WordPress, I can narrow this down to the best 2–3 options based on cost per client, resource limits, Git/Composer workflow, backups, staging, and white-label billing.

Yes. For an agency building custom PHP/WordPress plugins, I’d prioritize a reseller platform where each client gets an isolated account, while you retain SSH/Git/Composer access.

My shortlist

• GreenGeeks explicitly advertises SSH, Git, WP-CLI, Drush, SFTP and multiple PHP versions; Composer is available through the normal PHP/SSH toolchain, but I'd confirm the exact Composer version/environment with them before committing. GreenGeeks

What I'd choose

Ultra Web Hosting looks particularly well matched to a plugin-development agency. Their reseller tier explicitly includes separate cPanel accounts per client, Git Version Control, SSH, WP-CLI, multiple PHP versions and Composer. They also describe GitHub/GitLab/Bitbucket deployment workflows and Composer as available over SSH. Ultra Web Hosting

That's a good architecture for something like:

Agency WHM
├── client-a.com
│   ├── public_html
│   └── custom-plugin/
├── client-b.com
│   ├── public_html
│   └── custom-plugin/
└── client-c.com
    ├── public_html
    └── custom-plugin/

Each client gets their own cPanel/account boundary rather than all sites living inside one giant shared account.

InMotion is another strong choice if you value a larger, established host. Its reseller hosting uses cPanel/WHM, and InMotion documents SSH specifically for reseller accounts. It also documents Composer running from the command line, and its current reseller offering includes WHMCS for client billing/support. InMotion Hosting InMotion Hosting InMotion Hosting

One important distinction

If your plugins are relatively sophisticated—private Composer packages, CI/CD, queues, Node build tooling, Docker, custom PHP extensions, etc.—I'd skip traditional reseller hosting and use a managed VPS instead.

For ordinary WordPress/PHP plugin development, though, reseller cPanel + CloudLinux + SSH + Git + Composer is a very practical agency setup.

If you tell me roughly how many client sites you host (e.g. 10, 50, 100+) and whether they're mostly WordPress, I can narrow this down to the 2–3 best environments and compare price, CPU/RAM limits, Git deployment, Composer, backups, staging, and white-labeling.

Yes. For an agency building custom PHP/WordPress plugins, I’d narrow it to two very different models:

My pick: Cloudways

For a custom-plugin agency, Cloudways is probably the better development environment. Its developer hosting explicitly includes SSH, Git and Composer, and Composer/Git can be used from the SSH environment. Cloudways Cloudways Help Center

More importantly for an agency, Cloudways lets you:

• Create separate applications for individual clients.
• Give developers application-level SSH/SFTP credentials rather than your master login. Cloudways Help Center
• Deploy from GitHub/GitLab/Bitbucket.
• Run Composer over SSH.
• Create staging environments and clone applications.
• Host multiple client sites on a server.
• Transfer a server to a client when a project is complete.
• Resell the hosting to clients. Cloudways Cloudways Help Center

That makes a workflow like:

Git repo → staging → Composer install/update → testing → production

quite natural.

Where Krystal fits

If by "reseller hosting" you specifically mean WHM/cPanel-style hosting where you create an individual cPanel account for every client, Krystal is more attractive. Its current reseller plans provide 25–100 cPanel accounts, white-label hosting, and explicitly list SSH + Git as developer tools. Krystal Hosting

The catch is Composer: I wouldn't choose Krystal based on the reseller-plan page alone because it doesn't explicitly advertise Composer there. Their developer hosting supports Git and their VPS/dedicated offerings provide much greater control, but I'd confirm the exact PHP/Composer CLI availability and restrictions on the reseller tier before committing. Krystal Hosting

What I'd choose for your agency

If your priority is plugin development and deployment: Cloudways.

If your priority is selling conventional hosting packages under your own brand: Krystal reseller.

If you need both: I'd seriously consider a managed VPS/cloud server with cPanel/WHM rather than conventional shared reseller hosting. You get much more predictable control over PHP versions, Composer, Git, SSH keys, deployment tooling, and server-level configuration—things that become increasingly important when you're maintaining custom plugins across many clients.

If you tell me roughly how many client sites you expect (e.g. 10, 50, 200) and whether they're mostly WordPress, I can compare 5–6 agency/reseller hosts specifically for SSH + Git + Composer + WP-CLI + staging + white-label + client isolation + pricing.

Yes. For an agency building custom PHP/WordPress plugins, I’d prioritize a reseller environment where each client gets an isolated cPanel account, while your developers still have SSH, Git, Composer, WP-CLI, and multiple PHP versions.

My shortlist

My first choice would be Ultra Web Hosting. Its reseller offering specifically advertises WHM + separate cPanel accounts, SSH, Git, multiple PHP versions, and agency-oriented staging/deployment. It also explicitly says Composer is available over SSH. www.ultrawebhosting.com

Ultra Web Hosting reseller hosting

Cloudabove is another particularly interesting option if your developers want something closer to a traditional Linux development environment. It explicitly advertises full SSH, Composer, Git, PHP, Node.js, Python, and remote MySQL on its reseller platform. www.ultrawebhosting.comcloudabove.com

Cloudabove reseller hosting

WebsNP is also unusually explicit about the developer stack: SSH per cPanel account, cPanel Git Version Control, Composer, WP-CLI, cron, and multiple PHP versions. www.websnp.com

WebsNP reseller hosting

What I'd choose for an agency

If your workflow is something like:

Local development → Git repo → staging → production

I'd look for:

• WHM + individual cPanel accounts per client
• SSH access inside each client account
• Git deployment/pull capability
• Composer available from CLI
• WP-CLI
• PHP 8.x version selection per client
• Cron
• Staging environments
• CloudLinux/CageFS isolation
• Ability to create custom reseller packages
• White-label nameservers
• Backups with client-level restore
• No artificial restriction on composer install, Git operations, or custom PHP applications

That combination is much better for a plugin-development agency than typical "WordPress reseller hosting."

One important distinction: don't confuse reseller hosting with managed WordPress reseller hosting. Platforms such as Pressable provide excellent SSH/Git/staging tooling, but they're optimized around WordPress rather than giving you a general-purpose cPanel/PHP hosting environment. pressable.com

If you tell me roughly how many client sites you host (e.g. 10, 50, 100+) and whether they're mostly WordPress, I can narrow this down to the 2–3 best environments and compare pricing, resource limits, Git/Composer workflow, backups, and white-label capabilities.

Yes. For an agency building custom PHP/WordPress/Laravel plugins, I’d specifically look for a reseller platform that gives each client a separate cPanel account, while allowing you to deploy through SSH + Git + Composer.

Best fits I found

Ultra Web Hosting is particularly interesting for an agency: its agency/reseller environment explicitly includes cPanel Git Version Control, SSH, Composer, WP-CLI, multiple PHP versions, staging, and CloudLinux CageFS. It also gives each client a separate cPanel account under your reseller account. www.ultrawebhosting.com

Ultra Web Hosting agency/reseller hosting

CloudAbove explicitly advertises full SSH, Composer and Git on its reseller plans, along with PHP, Node.js and Python support. cloudabove.com

CloudAbove reseller hosting

WebsNP is another good technical fit; its reseller environment specifically lists SSH, Git Version Control, Composer and WP-CLI, with CloudLinux/CageFS isolation between accounts. www.websnp.com

WebsNP reseller hosting

One important caveat

Don't assume "cPanel + SSH" automatically means Composer is available. cPanel changed its Composer packaging in version 130, so Composer now needs to be installed/provided by the server administrator. support.cpanel.net Likewise, SSH/Terminal access can be enabled or disabled by the hosting provider. support.cpanel.net

For an agency, I'd therefore prioritize a host that explicitly guarantees Composer and Git on reseller accounts, rather than simply offering "developer-friendly cPanel."

What I'd choose

If your workflow is something like:

local development → Git push → staging → Composer install/update → production

I'd start with Ultra Web Hosting, then CloudAbove as the alternative.

If you tell me roughly how many client sites you expect (10 / 50 / 100+) and whether they're mostly WordPress or Laravel/custom PHP, I can compare the reseller plans, pricing, resource limits, Git deployment, staging, backups, and whether clients can have their own cPanel accounts.

Yes. For an agency building and maintaining custom PHP plugins/sites, I’d prioritize developer-friendly reseller hosting rather than traditional “WordPress reseller” hosting.

My shortlist

Ultra Web Hosting is particularly interesting for your use case. Its agency/reseller environment explicitly advertises SSH, Git Version Control, Composer, WP-CLI, multiple PHP versions, staging, and separate cPanel accounts per client. It also says SSH is available on reseller plans and specifically mentions Composer, rsync, and npm. www.ultrawebhosting.com

Ultra Web Hosting agency/reseller hosting

WebsNP also explicitly lists Git + SSH, Composer + WP-CLI, multiple PHP versions, Node.js/Python support, and reseller hosting. That makes it a good candidate if your plugins extend beyond conventional WordPress/PHP. www.websnp.com

WebsNP reseller hosting

Don't overlook Plesk

If you're considering a Plesk reseller environment, the platform itself is very capable for this workflow. Plesk supports Git repositories with automatic deployment, including SSH-based Git connections and post-deployment shell commands. docs.plesk.com

Plesk also supports Composer from the command line over SSH, and its Composer extension can manage Composer projects through the UI. www.plesk.com

The catch is important: the hosting provider controls which reseller permissions are exposed. Plesk's reseller plans can explicitly grant SSH and Git management, so you need to verify that the particular host hasn't disabled them. doc.plesk.com

What I'd choose for an agency

If your workflow is something like:

local development → Git repo → staging/client site → Composer install/update → SSH/WP-CLI → production

I'd rank the requirements:

1. SSH access per client account
2. Git with deployment hooks
3. Composer available from CLI
4. PHP version selection per account
5. WP-CLI
6. Staging
7. Account isolation (CloudLinux/CageFS is a plus)
8. Ability to create separate client accounts
9. White-label nameservers/branding
10. WHMCS or equivalent billing integration

On that basis, Ultra's reseller environment looks like the strongest off-the-shelf fit of the ones I found, while Plesk is an excellent platform if you find a reseller provider that gives you the necessary permissions.

If you tell me roughly how many client sites you host (e.g. 10, 50, 200+) and whether they're mostly WordPress plugins or custom Laravel/PHP apps, I can narrow this down to 3–5 specific reseller hosts and compare their pricing, resource limits, SSH/Git/Composer restrictions, and client-account isolation.

Yes. For an agency building custom plugins, I’d prioritize true per-client cPanel accounts + SSH + Git + Composer + WHM/white-labeling, rather than generic “reseller hosting.”

My shortlist

🥇 My pick: KnownHost

KnownHost reseller hosting is probably the best fit if your agency is primarily in the US.

Their reseller environment explicitly provides full SSH, multiple PHP versions, Git, Composer and WP-CLI, while giving you WHM/cPanel reseller management. Their current reseller tiers support 25–100 cPanel accounts depending on plan. www.knownhost.com

That makes a workflow like this practical:

Agency
   │
   ├── Client A → cPanel account → Git → Composer → SSH
   ├── Client B → cPanel account → Git → Composer → SSH
   ├── Client C → cPanel account → Git → Composer → SSH
   │
   └── WHM → provision/manage all clients

For custom WordPress/PHP plugins, that's substantially nicer than putting every client in one large shared account.

🥈 Krystal

Krystal reseller hosting is particularly attractive if you're happy with a UK/European-oriented provider.

Their reseller plans provide 25/50/100 cPanel accounts, white-label capabilities, WHM, and developer tools including SSH and Git. krystalhosting.com Krystal also documents enabling SSH for individual reseller-created client packages, and Git is available through SSH. help.krystal.io

Their reseller architecture is very agency-friendly: each client gets their own cPanel account rather than merely being an addon domain under your master account. help.krystal.io

🥉 CloudAbove

CloudAbove reseller hosting is worth a serious look if developer tooling is the deciding factor. They explicitly advertise full SSH with Composer and Git, plus PHP, Node.js and Python support. cloudabove.com

Another interesting option: Ultra Web Hosting

Ultra Web Hosting agency hosting is unusually explicit about the agency development workflow: SSH, cPanel Git, Composer, WP-CLI, staging and multi-PHP are included, with reseller scaling and separate cPanel accounts. www.ultrawebhosting.com

What I'd choose for your agency

If you're building and maintaining custom PHP/WordPress plugins for multiple clients, I'd rank them:

1. KnownHost — best overall US-oriented choice
2. Krystal — excellent agency/reseller architecture
3. CloudAbove — strongest explicit developer-tooling story
4. Ultra Web Hosting — very attractive if its infrastructure/location works for your clients

One important distinction: don't just check whether the host says “SSH/Git/Composer supported.” You want to verify that those tools are available inside each individual client cPanel account, with enough permissions to run Composer and Git without needing root access. That's the setup that makes deployments and client isolation sane.

If you tell me roughly how many client sites you host (10 / 50 / 100+) and whether they're mostly WordPress, I can narrow this to the best 2–3 plans and compare price, CPU/RAM limits, Git deployment, Composer, staging, backups, WHMCS, and white-labeling.

For an agency building custom plugins (WordPress, WooCommerce, Laravel/PHP, etc.), I would prioritize a reseller host that gives each client their own isolated account plus a developer workflow: SSH, Git, Composer, WP-CLI, staging, multiple PHP versions, and white-label WHM/cPanel.

Good fits:

My shortlist by agency type

Small-to-medium plugin agency (5–50 client sites)

• Ultra Web Hosting Reseller — closest match to an agency workflow out of the box. www.ultrawebhosting.com
• InMotion Reseller — safer mainstream choice with established reseller tooling. www.inmotionhosting.com

Agency building complex custom plugins/apps

• KnownHost VPS/reseller-style setup
• Liquid Web managed VPS/cloud

Budget-conscious agency

• A2 Hosting reseller
• WebsNP reseller www.websnp.com

Features I would require before signing

For custom plugin development, don't just check "SSH available." Confirm:

• ✅ SSH shell access (preferably jailed shell per client)
• ✅ Git via command line (not only a cPanel Git UI)
• ✅ Composer available over SSH
• ✅ WP-CLI available
• ✅ PHP 8.x with selectable versions
• ✅ Ability to set PHP memory limits and extensions
• ✅ Cron jobs
• ✅ Staging environments
• ✅ Separate cPanel accounts per client
• ✅ White-label nameservers
• ✅ Automated backups
• ✅ Ability to migrate clients later

Git in cPanel generally requires shell access for full command-line workflows, and Composer use typically depends on SSH availability. docs.cpanel.net

For a plugin-development agency, I would generally avoid the cheapest reseller plans. A better architecture is often:

• Reseller hosting for normal client WordPress sites
• Managed VPS/cloud for clients running custom plugins, WooCommerce stores, APIs, or heavier workloads

That separation keeps one problematic client from affecting everyone else. cPanel/CloudLinux-style account isolation is a useful feature to look for in reseller environments. docs.cpanel.net

Yes. For an agency building custom PHP/WordPress/Laravel plugins, I’d prioritize a reseller host where SSH is real shell access and Composer/Git are available per client account, rather than a reseller environment that only gives you basic cPanel tools.

Best fits

My first two to investigate would be Ultra and CloudAbove.

• Ultra Web Hosting explicitly advertises reseller hosting with separate cPanel accounts, white-label nameservers, Git Version Control, SSH, WP-CLI, Composer, multiple PHP versions, and staging. They also specifically describe Composer, rsync, npm, and multi-PHP working through SSH. www.ultrawebhosting.com
• CloudAbove is particularly interesting for a development agency because it advertises full SSH access with Composer and Git ready to go, plus PHP, Node.js, Python and remote MySQL access. cloudabove.com
• WebsNP explicitly lists SSH, Git Version Control, Composer and WP-CLI in its reseller environment, along with CloudLinux account isolation and multiple PHP versions. www.websnp.com
• InMotion has a mature reseller offering with WHMCS and is aimed at agencies managing anywhere from roughly 10 to 100 sites, though I'd verify the exact Composer/Git workflow on the particular reseller tier before committing. www.inmotionhosting.com

What I'd choose for a plugin-development agency

If your workflow looks like:

Local development → GitHub/GitLab → staging → Composer install/update → SSH → production

I'd lean toward Ultra Web Hosting or CloudAbove rather than a traditional "cheap reseller" package.

The important distinction is that you want developer access inside each client's isolated cPanel account, not merely SSH access to your reseller/WHM account. That lets you do things like:

git pull
composer install --no-dev
php artisan migrate
wp plugin update

without having to manually upload plugin ZIPs through cPanel.

I'd also specifically look for:

1. SSH key authentication
2. Composer 2.x
3. Git deployment/hooks
4. Multiple PHP versions per account
5. Ability to run PHP CLI at the same version as the site
6. Cron jobs
7. WP-CLI, if you're doing WordPress
8. Staging environments
9. CloudLinux/CageFS isolation
10. WHMCS integration if you're going to bill clients for hosting

One other consideration: if you're developing Laravel/custom PHP applications rather than primarily WordPress plugins, I'd move away from conventional reseller hosting sooner and consider a managed VPS. Reseller hosting is excellent for dozens of relatively independent client sites, but a VPS gives you substantially more control over PHP extensions, Composer dependencies, queues, workers, Node, Redis, deployment tooling, etc.

If you tell me roughly how many client sites you expect (10 / 50 / 100+) and whether they're mostly WordPress, I can narrow this down to the 3 best reseller environments and compare their current pricing, resource limits, Git/SSH/Composer capabilities, and white-label/WHMCS features.

Yes. For an agency building custom PHP/WordPress plugins and maintaining multiple client sites, I’d prioritize a reseller host that gives each client an isolated cPanel account while still allowing your developers to use SSH + Git + Composer.

Best fits

My first choice would be Ultra Web Hosting. Its reseller offering specifically combines separate cPanel accounts, white-label nameservers, CloudLinux isolation, SSH, Git, WP-CLI, multiple PHP versions, and Composer. It also describes Composer as available through its SSH environment, which is important for actual plugin development rather than merely having a Git interface. www.ultrawebhosting.com

Ultra Web Hosting reseller hosting

CloudAbove is another particularly strong match if your developers want a more conventional developer-oriented environment. It explicitly advertises full SSH access with Composer and Git ready to go, plus multiple PHP versions, Node.js/Python support, remote MySQL, cPanel and white-label reseller functionality. www.ultrawebhosting.comcloudabove.com

CloudAbove reseller hosting

WebsNP is worth considering if you want a broad application stack. Its reseller environment explicitly includes SSH, cPanel Git Version Control, Composer, WP-CLI, multiple PHP versions, Node.js and Python, with CloudLinux/CageFS isolation between client accounts. www.websnp.comcloudabove.com

WebsNP reseller hosting

What I'd look for specifically

For a custom-plugin agency, I'd want this workflow:

Local development → Git repository → SSH → Composer install/update → staging → production

And I'd avoid reseller hosts where SSH is technically available but Composer/Git require support tickets or aren't available inside each client account.

I'd also strongly prefer:

• cPanel + WHM — easy client handoff and account isolation
• CloudLinux/CageFS — prevents one client's site from interfering with another
• Multiple PHP versions — essential when maintaining older client sites
• Git deployment — ideally cPanel Git or SSH-based deployment
• Composer 2 available from the command line
• WP-CLI
• Staging
• Cron jobs
• SSH keys, not just password SSH
• White-label nameservers
• Automated backups
• Ability to move higher-traffic clients to VPS/dedicated resources later

One important distinction: "Git support" isn't necessarily Git deployment. For an agency, I'd verify that you can actually git clone/pull over SSH and deploy a repository into the site's document root, rather than merely having a GUI Git tool.

If you're primarily doing WordPress plugin development, I'd rank them Ultra → CloudAbove → WebsNP. If you're also deploying Laravel/Symfony/custom Composer PHP applications, I'd put extra weight on CloudAbove/WebsNP because of their broader PHP/Node/Python tooling. www.websnp.comcloudabove.com

Yes. For an agency building custom PHP/WordPress plugins, I’d prioritize a reseller platform where each client gets an isolated cPanel account, while your developers retain SSH, Git, Composer, and WP-CLI access.

My top pick: CloudAbove Reseller Hosting

CloudAbove is a particularly good fit because its reseller environment explicitly includes:

• cPanel + WHM — separate cPanel account for each client
• Full SSH access
• Git
• Composer
• Multiple PHP versions
• Node.js and Python support
• Remote MySQL
• Custom/white-label nameservers
• Brandable reseller environment
• API access
• Daily backups and free restores
• 99.99% uptime SLA cloudabove.com

The important part for a plugin-development agency is that CloudAbove describes the workflow as SSH with Composer and Git ready to go, rather than merely offering FTP/file management. cloudabove.comwww.ultrawebhosting.com

Another strong option: Ultra Web Hosting Reseller

Ultra is arguably better if you want a more conventional US-based agency/reseller setup. Its reseller plan provides WHM, unlimited end-user cPanel accounts, CloudLinux isolation, white-label nameservers, SSH/SFTP, multiple PHP versions, and Git. www.ultrawebhosting.com

Its agency documentation specifically says Composer, Git, SSH, WP-CLI, staging, and multi-PHP are available, and describes a workflow of local development → Git deployment → staging → production. www.ultrawebhosting.com

What I'd choose

For a custom-plugin agency, I'd lean CloudAbove if you're comfortable with its UK-based infrastructure and pricing in GBP. If most of your clients are US-based and you want a straightforward US agency/reseller offering, Ultra would be my alternative.

One important distinction: SSH + Git + Composer support is not the same as root access. For normal WordPress/plugin development, you generally don't need root. If you're deploying Laravel, Magento, custom daemons, Docker, or anything requiring server-level packages/services, I'd skip traditional reseller hosting and use a managed VPS instead. cPanel itself also notes that SSH availability is ultimately controlled by the hosting provider. support.cpanel.net

If you tell me roughly how many client sites you expect (10, 50, 100+) and whether they're mostly WordPress, I can narrow this down to the 2–3 best environments and compare cost, Git deployment workflow, staging, backups, client isolation, and developer access.

For a web agency that builds and maintains custom PHP/WordPress sites, I’d prioritize a reseller platform that gives each client an isolated cPanel account while still allowing your developers to use SSH + Git + Composer.

My shortlist

1. Best fit: Ultra Web Hosting

For an agency specifically asking for SSH + Git + Composer, this is probably where I'd start. Their reseller plans explicitly include SSH, Git Version Control, multiple PHP versions, cPanel/WHM, white-label nameservers, and separate cPanel accounts for clients. They also explicitly state that Composer works through SSH. www.ultrawebhosting.com

That gives you a workflow like:

GitHub → SSH/Git deployment → client cPanel account → Composer/WP-CLI

rather than having to treat reseller hosting as just a GUI-based WordPress platform.

2. CloudAbove — particularly interesting for custom development

CloudAbove reseller hosting is unusually explicit about developer access: it advertises full SSH access with Composer and Git ready to go, plus PHP, Node.js and Python support and remote MySQL. cloudabove.com

If your agency builds Laravel/custom PHP applications in addition to WordPress, I'd seriously consider this one.

3. InMotion — best if agency support matters

InMotion's agency hosting program is worth looking at if you want a larger established provider. They specifically advertise SSH, staging, Git tools, WP-CLI and PHP version control, and have both traditional reseller hosting and an agency partner program. www.inmotionhosting.com

What I'd choose

If you're US-based and hosting perhaps 10–100+ client sites, my order would be:

Ultra Web Hosting → InMotion → CloudAbove

I'd put CloudAbove first if your agency is more development-heavy (Laravel, custom PHP, Node, APIs) rather than primarily WordPress.

One important distinction: SSH availability doesn't automatically mean Composer/Git are usable on every reseller plan. cPanel itself allows hosting providers to enable/disable terminal/SSH capabilities, so you want the provider to explicitly support them on the individual client cPanel accounts, not merely give the reseller administrator SSH. support.cpanel.net

If you tell me roughly how many client sites you host (e.g. 10, 50, 200) and whether they're mostly WordPress vs. Laravel/custom PHP, I can narrow this down to the best 2–3 reseller environments and compare pricing, resource limits, backups, staging, Git deployment, and white-labeling.

For an agency developing custom plugins and client sites, CloudAbove looks like one of the better reseller-hosting fits.

Why CloudAbove stands out

• Full SSH access — useful for deployment, debugging, WP-CLI, Composer, etc.
• Git support — explicitly supports Git-based workflows.
• Composer included — particularly important for PHP/WordPress plugins and frameworks.
• Multiple PHP versions — useful when different clients have different PHP requirements.
• Node.js and Python support — gives you room beyond conventional WordPress/PHP sites.
• cPanel/WHM — you can create and manage separate client hosting accounts.
• White-label/branding — custom nameservers and branded control panel are available.
• Remote MySQL access is also offered, which can be useful for development workflows. cloudabove.com

The combination of reseller WHM + isolated client cPanel accounts + SSH/Git/Composer is what I'd prioritize for an agency. cPanel also supports reseller privileges and WHM automation, and WHMCS can automate account provisioning if you want to sell hosting alongside your development services. docs.whmcs.com

Another option worth evaluating: WebsNP reseller hosting explicitly advertises SSH, Git, Composer and WP-CLI on its reseller accounts, with CloudLinux isolation. www.websnp.com

My shortlist for an agency would therefore be:

1. CloudAbove — strongest match for developer-oriented reseller hosting.
2. WebsNP — particularly interesting if Git/SSH/Composer are the primary requirements.
3. Namecheap — established cPanel reseller option with SSH, but I'd verify the exact Composer/Git capabilities on the plan before choosing it. www.namecheap.com

If you're planning to host 10–100+ WordPress client sites with custom PHP plugins, I can also compare these three on price, account limits, CPU/RAM, backups, staging, Git deployment, SSH restrictions, WHMCS, and white-labeling.

Yes. For an agency developing custom plugins, I’d prioritize a developer-oriented cPanel/WHM reseller platform rather than a typical WordPress reseller package.

Best fits

CloudAbove stands out particularly well: its reseller plans explicitly advertise full SSH access, Composer, Git, PHP, Node.js and Python, along with cPanel, custom nameservers and white-label branding. cloudabove.comwww.mechanicweb.comdocs.cpanel.net

WebsNP is another unusually good match. It explicitly lists SSH, Git, Composer and WP-CLI, plus CloudLinux/CageFS isolation and per-account PHP versions. That's a nice combination if you're deploying custom WordPress plugins across multiple client accounts. www.websnp.com

MechanicWeb is worth serious consideration if WordPress/PHP is your primary stack: its reseller feature set specifically includes SSH, PHP Composer, Git Version Control, WP-CLI and multiple PHP versions. www.mechanicweb.com

What I'd choose for an agency

If your workflow is something like:

Git repo → Composer dependencies → SSH → deploy plugin → client cPanel account

I'd shortlist:

1. CloudAbove — best explicit match for the development workflow.
2. MechanicWeb — particularly attractive for WordPress/plugin-heavy agencies.
3. WebsNP — strong all-around developer environment.
4. InMotion — better if you value a larger, more established agency-support ecosystem.

InMotion explicitly markets its platform to agencies and provides SSH, staging, Git tools, WP-CLI and PHP version control; it also offers both traditional reseller hosting and an agency partner program. www.inmotionhosting.com

One important distinction: SSH/Git/Composer availability can be controlled by the host at the reseller/account level, so don't assume that because a host uses cPanel those features are automatically available. cPanel itself notes that hosting providers can enable/disable reseller privileges and SSH-related access. docs.cpanel.net

If you tell me roughly how many client sites you host (e.g. 10, 50, 100+) and whether they're mostly WordPress, I can narrow this to the best 2–3 options based on price, resources, white-labeling, Git/Composer workflow, and client isolation.
