Coolify Review 2026: Self-Hosted PaaS, Cloud Price, Limits

Coolify turns a rented server into your own Heroku: connect a git repo, push, and it builds a container, routes a domain to it and renews the TLS certificate. The software is free, so the real question is whether the hours you spend running it cost less than a managed platform's markup.

For a solo developer or a small team with one or two apps, the answer is usually yes. For a team without anyone who wants to read server logs at 2am, it is usually no.

Toolradar data: of the 38 container orchestration tools in Toolradar's catalog, 35 have a free plan, and Coolify is listed as an alternative to 6 tools, joint #12 of the 38 on that measure, as of October 2026 (Coolify on Toolradar).

A free tier is therefore table stakes here, and the differences sit in footprint, managed options and how much work each tool leaves to you.

This review covers what Coolify includes, what the Cloud edition really bills, and when Railway, Render or another self-hosted panel is the better buy. The wider field is ranked in our self-hosting tools roundup.

Coolify is an open-source, self-hostable platform-as-a-service, licensed under Apache-2.0 and maintained by coolLabs on GitHub, where the repository had over 63,000 stars on 21 October 2026.

It describes itself as an alternative to Vercel, Heroku, Netlify and Railway, and it deploys static sites, full-stack apps, databases and 360+ one-click services to any server it can reach over SSH.

The project ships often. Version 4.4.0, released on 6 October 2026, added built-in traffic analytics for the Traefik and Caddy proxies, experimental SQLite databases, OpenID Connect sign-in, Cloudflare DNS management and GitHub Actions runners on build servers, and six patch releases followed within three days.

That pace is good news for features and a reminder that a self-hosted instance needs regular updates. If you are leaving a managed host, our Heroku alternatives ranking places Coolify among the managed and self-hosted options.

You install Coolify on one Linux server with a single install script, or you sign up for Coolify Cloud and let coolLabs host the dashboard. Then you connect the servers your apps will run on. Coolify's docs list the minimum for the machine that runs Coolify itself as 2 CPU cores, 2 GB of RAM and 10 GB of free disk, on amd64 or arm64.

The docs add that it can run on 1 core, 512 MB of RAM and 4 GB of disk, but they do not recommend it, and they warn that running builds on the same small server can make it unresponsive.

Builds use Nixpacks, Railpack, a Dockerfile or Docker Compose, or a prebuilt image from a registry. One-click databases cover PostgreSQL, MySQL, MariaDB, MongoDB, Redis, KeyDB, Dragonfly and ClickHouse, with scheduled backups to any S3-compatible bucket.

Pull requests can get their own preview deployments, and an MCP server lets an AI agent list resources, deploy and read logs with your existing API tokens.

The split between the two editions is about who runs the control panel. Self-hosted, you own the Coolify instance: its domain, its backups, its updates and its email alerts, which need your own SMTP or Resend account. On Cloud, coolLabs runs the dashboard at app.coolify.io and manages those pieces, while your apps still run on servers you rent.

Our guides to deploying Next.js without Vercel and self-hosting n8n show what that setup looks like in practice.

Coolify suits developers and small teams who already rent a VPS and want a dashboard on top of it. It fits side projects, agencies hosting many small client sites, and startups that want staging and production on separate cheap servers without a per-service markup.

Our cheap VPS ranking and the Hetzner review cover servers that meet Coolify's minimum spec.

It is a poor fit if no one on the team wants to own a server. Coolify's GitHub repository lists 70 published security advisories, 21 rated critical, and 16 of those critical ones were published in 2026, as of 21 October 2026.

The project fixes and discloses them publicly, which is the right behaviour, but every advisory is an update you must apply on a self-hosted instance. Teams that want vendor-run patching, support response times or a compliance package should start with Render or Heroku.

Teams moving off Heroku can compare both routes in our Heroku migration guide.
