Dokku Alternatives: Minimal Self-Hosted PaaS Options
Dokku is the minimalist's choice for self-hosted PaaS. Compare it with alternatives for teams that want more or less.
Dokku calls itself "a checkpoint-based platform-in-a-box" — essentially, a mini-Heroku you run on any Linux machine. Git-push deploys, buildpacks, and plugins for databases. The philosophy is minimal: Dokku does one thing and defers everything else to the underlying OS.
Dokku's Appeal
No web UI to maintain, no additional services to run. Everything is command-line. The resource footprint is tiny (512MB RAM can run Dokku + several apps). For developers who prefer CLI tools, it's refreshingly simple.
Why Look for Alternatives
Dokku's simplicity is also its limitation. Documentation can be sparse. Plugin ecosystem is smaller than CapRover or Coolify. Some teams find the git-push workflow limiting for more complex pipelines.
Best Alternatives
Coolify: More features, web UI, easier onboarding. Better for teams without strong git workflow preferences.
CapRover: Similar to Coolify, slightly older. More battle-tested but less actively developed.
Porter: More opinionated, more managed-feeling. Good if you want something between self-hosted and managed.
Railway: If you can afford it, Railway's DX is closer to Dokku's simplicity with zero server management.
When to Choose Dokku
Dokku is right for developers who are comfortable on the command line, want minimal infrastructure to manage, and are deploying applications that fit the buildpack model.
Running an AI Assistant Gateway?
Dokku and its alternatives are all designed for deploying web apps. If you specifically want to run OpenClaw — an open-source AI assistant that connects to Telegram, Discord, or Slack — the full self-hosted setup (Docker, volumes, env management) can take hours.
EZClaw skips all of that: one form, under a minute, OpenClaw live on Fly.io with persistent storage included.
