Coolify vs CapRover: self-host your apps on a cheap server.

Coolify vs CapRover

Hosted platforms like Heroku, Vercel and Render are great until the bills stack up: one charge for the app, another for the database, another for the worker that sends emails. Self-hosting flips the deal. You rent one plain server, and a free tool handles the boring parts of putting code online.

Coolify and CapRover are two well-known tools for that job. Both are open source and free to self-host, but they make different trade-offs.

01What a self-hosted PaaS actually is

A PaaS (platform as a service) is where you hand over code and get back a running app with a URL, without installing web servers or renewing certificates yourself. A self-hosted PaaS gives you that on a machine you control, usually a VPS (virtual private server): a rented slice of a computer in a data centre. Three pieces do the heavy lifting:

• Docker packages each app and everything it needs into a "container" that runs the same on any server.
• A reverse proxy sits at the front door, reads which domain a visitor asked for, sends them to the right container, and handles HTTPS.
• A dashboard ties it together, so you click "deploy" instead of typing twenty commands.

02Meet the two tools

Coolify

Coolify is built by coolLabs, a team led by founder Andras Bacsai, and is licensed under Apache 2.0. Its README describes it as "an open-source and self-hostable alternative to Heroku, Netlify, and Vercel." It connects to servers over SSH, builds from GitHub, GitLab, Bitbucket or Gitea, and lists "more than 360 one-click services". It also schedules database backups, spins up pull-request previews and manages several servers from one dashboard. The latest release was v4.4.6, published October 9, 2026.

CapRover

CapRover is a more compact project. Under the hood it's Docker, the nginx web server, Let's Encrypt for free HTTPS certificates and Docker Swarm for clustering. A small file called captain-definition tells it how to build each app, and databases come from a list of one-click apps. Its README says all you need is "Copy & Paste" knowledge, which is the project's own pitch. The latest release was v1.15.4, published August 30, 2026.

03Side by side

In short: Coolify ships more out of the box, especially around data. CapRover keeps a tighter scope.

04How git push deploys work

Push code to GitHub, and the live site updates. Both tools document the same basic flow.

With CapRover, the captain-definition file at your repo's root points to a Dockerfile, a built-in Node, PHP, Python or Ruby template, or a ready-made image. Coolify can often work out the build itself with a tool called Nixpacks, or use your Dockerfile.

The whole captain-definition for this site is four lines:

{
  "schemaVersion": 2,
  "dockerfilePath": "./Dockerfile"
}

05What it costs

Both tools are free to self-host. Coolify's pricing page says "Free forever" with no feature limits, and so does CapRover's homepage. Your real bill is the server, the domain and any backup storage. The only official price here is Coolify Cloud, which runs the Coolify dashboard for you while your apps stay on servers you bring.

Server prices vary too much by provider to chart fairly; CapRover's docs say "as low as $5 a month". Mind the minimums: Coolify asks for 2 GB of RAM, and CapRover warns that 512 MB "might not be enough" because builds are memory-hungry.

06Community and activity

Both projects are alive: each had commits on its main branch on October 19, 2026. Coolify's community is far bigger. GitHub listed 698 contributors and 713 releases for Coolify, against 74 contributors and 43 releases for CapRover. More people usually means more tutorials and answers, and more releases mean more updates to apply.

07The catches: you are the ops team now

Self-hosting saves money because you do the work a hosting company would charge for.

• Updates are your job. Coolify can update itself on a schedule, but its docs say that covers only Coolify, not your apps, databases or the server's operating system. CapRover offers upgrades through a dashboard banner. Read release notes first.
• Backups are your job. Coolify schedules database dumps to S3-compatible storage, but its docs warn that "a backup is not a restore test". CapRover's experimental backup skips Docker images and volumes, where database data lives, so plan your own dumps.
• Security is your job. Coolify's docs warn that whoever reaches the registration page first "can become the instance admin and gain root access to your server", so register right away. CapRover starts with the password captain42; change it once HTTPS works.
• One server is one point of failure. If it dies, every app on it goes down. Coolify's README recommends one server for Coolify and others for your apps.
• Swarm is a split decision. CapRover's clustering runs on Docker Swarm, while Coolify calls its own Swarm support deprecated and will remove it in v5. Swarm itself lives on: Docker's docs describe it as built into Docker Engine, and Mirantis said in 2025 it will support Swarm through at least 2030 in its enterprise product.
• Read the fine print. CapRover's license adds an appendix to Apache 2.0; for example, modifications of free features "should be distributed as free & opensource software". Since v1.11 it also sends anonymous usage analytics, which CAPROVER_DISABLE_ANALYTICS=true switches off.

08Which should you pick?

Two questions settle most cases: how much do you want built in, and how many servers?

For a founder with an app, a Postgres database and a few side tools such as n8n for automation or Listmonk for newsletters on one server, Coolify is the more complete package, mainly because database backups are built in.

Pick CapRover if you like fewer moving parts: a few Dockerized apps, git push deploys, free HTTPS. It's also the natural choice if you want Docker Swarm clustering.

09How to try them

Use a fresh, throwaway server first. Coolify's installer runs as root; you can read the install script before running it:

curl -fsSL https://cdn.coollabs.io/coolify/install.sh | bash

Then open http://<your-server-ip>:8000, create the admin account immediately, and back up /data/coolify/source/.env, which holds Coolify's encryption key.

CapRover needs Docker plus a wildcard DNS record such as *.apps.yourdomain.com pointing at the server. Then run:

docker run -p 80:80 -p 443:443 -p 3000:3000 -e ACCEPTED_TERMS=true -v /var/run/docker.sock:/var/run/docker.sock -v /captain:/captain caprover/caprover

Finish setup from your laptop with the recommended CLI:

npm install -g caprover
caprover serversetup

10Verdict

Both tools deliver the core promise: push code, get a running app with HTTPS, on a cheap server. Coolify is the bigger, faster-moving project with more safety nets built in, plus a managed option. CapRover is smaller, simpler and has clustering built in. This site runs on it.

The real decision is whether you want to be your own ops team. If yes, start with one app, set up backups on day one, and practise a restore before you need it. If not, paying a hosted platform is a perfectly good founder decision.
