CapRover vs Coolify

CapRover and Coolify both promise the same thing: Heroku's deploy experience on a server you rent yourself. Both wrap Docker, both put a web dashboard in front of it, both terminate HTTPS for you, and both come with a catalog of one-click databases and services. Where they part ways is in how much platform they try to be. CapRover is the lean one, built on Docker Swarm with an nginx it manages. Coolify is the broad one, a Git-first control panel with build packs, preview deployments, and database backups built in, and it asks for more server to match.

Same job, different weight

CapRover is a TypeScript/Node.js application with a 1 GB floor and a 2 out of 5 deploy difficulty. Its own docs note that builds can eat more RAM than you expect, and that 512 MB may not be enough. You install it with one docker run and it takes over ports 80, 443, and 3000.

Coolify is a PHP/Laravel application with a 2 GB floor. Its installation docs ask for 2 CPU cores, 2 GB of RAM, and 10 GB of disk, and it rates the same 2 out of 5 here. A one-line install script sets up Docker and everything else, then serves the dashboard on port 8000. One detail from Coolify's own docs is worth knowing before you run it: whoever reaches the registration page first becomes the instance admin, so create your account the moment the installer finishes.

On paper the gap is one gigabyte. In practice it decides the question for anyone on the classic 1 GB entry-level box, where CapRover fits and Coolify does not.

Building and deploying

This is where Coolify pulls ahead. It builds straight from a GitHub, GitLab, Bitbucket, or Gitea repository using Nixpacks, Railpack (in beta), a static-site pack, a Dockerfile, or a Docker Compose file, redeploys on every push, and can spin up a separate preview deployment for each pull request, removing it again when the PR is closed or merged. If you want the Vercel-style workflow of a preview URL on every branch, Coolify has it and CapRover does not.

CapRover builds from a captain-definition file: a small set of built-in templates (Node, PHP, Python/Django, Ruby/Rack), a Dockerfile in your repo, an inline Dockerfile, or a prebuilt image. You deploy with the caprover deploy CLI, a tarball upload in the dashboard, or a webhook from GitHub, GitLab, or Bitbucket. That covers the common cases fine. It just asks you to write a bit more of the build yourself, and CapRover's own docs recommend a repository-owned Dockerfile for production anyway.

Scaling past one server: the reversal

Multi-server is the one area where the lighter tool has the stronger story. CapRover runs on Docker Swarm from the start. Add a node from the dashboard (or with plain Swarm commands), set a default Docker registry, and raise an app's instance count to run replicas across the cluster, with Swarm restarting any that crash. The catch, straight from the docs: only apps without persistent data can be spread across nodes.

Coolify manages extra servers over SSH. You can keep workloads off the machine running the dashboard, dedicate a build server, or deploy the same app to several standalone servers. Adding servers doesn't distribute traffic by itself, though. You put your own load balancer in front, and apps with persistent storage or Compose-based apps can't use it. Coolify's Swarm support is marked experimental and deprecated in its docs and is due to be removed in v5, so don't pick Coolify expecting a Swarm cluster.

If "several servers acting as one cluster" is a real requirement, CapRover handles it natively, and Dokploy is the Swarm-native option with a Coolify-style UI (see Coolify vs Dokploy).

One-click apps and HTTPS

Both ship a one-click catalog. CapRover's lives in its public one-click-apps repository and covers the usual databases, blogs, and dev tools. Coolify's README counts more than 300 one-click services, provisioned with persistent storage and generated credentials. Either will get you Postgres, a CMS, or a monitoring stack running in minutes.

For HTTPS, CapRover uses Let's Encrypt behind its nginx and needs a wildcard DNS record (*.apps.example.com) pointed straight at the server. Its docs don't officially support proxies like Cloudflare in front. Coolify defaults to Traefik, offers Caddy as an alternative, and issues certificates automatically with either.

Backups: what actually gets saved

This is the difference most likely to bite you later. CapRover's built-in backup captures its /captain/data directory, meaning app settings, configuration, and SSL certificates. It explicitly does not include container images or persistent directories. Your databases need their own dump or volume-snapshot routine.

Coolify schedules engine-aware database backups for PostgreSQL, MySQL, MariaDB, MongoDB, and ClickHouse, with optional upload to S3-compatible storage (Redis and its relatives are excluded). It also documents backing up and restoring the Coolify instance itself. Its docs also warn that a successful backup isn't a tested restore, which is good advice for both tools.

Licensing and project shape

Coolify is Apache-2.0, with a paid, hosted Coolify Cloud for people who would rather not run the control plane themselves. CapRover's license file is Apache-2.0 plus an appendix that overrides it where they conflict: CapRover's paid features can't be modified or redistributed without a written agreement, and modified free features must be released as free, open-source software. Its terms describe CapRover core as "free and source-available" with an optional paid CapRover Pro layered on top. CapRover also sends anonymous usage analytics by default, which you can turn off with CAPROVER_DISABLE_ANALYTICS=true. None of this touches ordinary self-hosting. It matters if you plan to fork or redistribute.

Who should pick neither

If you'd rather drop the dashboard entirely, Dokku is the CLI-only, git-push option and the thinnest layer of the three. See Dokku vs CapRover for how it compares to CapRover's approach.

Which should you self-host?

Pick CapRover if…

• Your server has 1 GB of RAM and you want a dashboard PaaS that fits on it.
• You want a real Docker Swarm cluster, with nodes added and replicas scaled from the UI, for stateless apps.
• You're fine writing a Dockerfile or captain-definition and handling database backups yourself.

Pick Coolify if…

• You want Git-push deploys with build packs, including Nixpacks, with no Dockerfile required.
• Preview deployments per pull request matter to your workflow.
• You want scheduled database backups to S3 built into the platform, and you can give it a 2 GB+ server.

Running either on a VPS

For most people choosing today, Coolify is the better platform. It covers builds, previews, and backups out of the box, and with CapRover you'd be scripting those yourself. Give it a real box: our Coolify deploy guide sizes it at 2 vCPU / 4 GB once a couple of apps are running alongside it. CapRover earns its place when the budget is a single 1 GB server, or when you want Swarm replicas without assembling a cluster by hand. Whichever you choose, sort out DNS before installing and set up off-box backups of the data your apps actually hold on day one (see restic vs Kopia). Neither platform does that part completely for you.
