We rate Dokku 4.1/5. Simplest self-hosted PaaS, making it especially useful for developers and solopreneurs. The main tradeoff: single-server only. The free tier softens this considerably.
About Dokku
Dokku is the minimalist's PaaS. It's a single bash script that turns any Ubuntu server into a Heroku-like deployment platform. `git push dokku main` deploys your app with zero-downtime.
Heroku buildpack compatibility means most Heroku apps work without changes. Dokku detects your app type (Node.js, Python, Ruby, etc.) and builds it automatically. Docker deployments are also supported.
The plugin system extends functionality: PostgreSQL, Redis, MySQL, Let's Encrypt SSL, cron jobs, and more. Each plugin installs with a single command.
Environment variable management, process scaling, and log tailing work just like Heroku. The CLI is the only interface — there's no web dashboard, keeping the system lean.
Completely free and open-source. Run it on any server: DigitalOcean ($4/month), Hetzner ($4/month), or your own hardware.
For solo developers who want Heroku's `git push` workflow without Heroku's bills, Dokku is the time-tested solution. It's been around since 2013 and is extremely stable.
Limitations: single-server only (no clustering), CLI-only with no web UI, scaling is limited to vertical (bigger server) rather than horizontal, and you need Linux server administration knowledge.
