Top open-source self-hosted PaaS platforms in 2025 — compared on features, ease of setup, and community health.
Open-source PaaS tools let you run a Heroku-like deployment platform on your own infrastructure. You get full data control, no vendor lock-in, and often significant cost savings at scale. The tradeoff is that you manage the underlying server. Here are the most widely-used options in 2025.
The most popular open-source self-hosted PaaS
CapRover is a free, open-source PaaS built on Docker Swarm and Nginx Captain proxy. One-click app library, automatic Let's Encrypt SSL, and a web UI for managing deployments on your own VPS.
Pricing
Free software. You pay for your own VPS (e.g., $5–$20/mo on Hetzner or DigitalOcean).
Best for
Teams that want full data ownership and are comfortable managing a VPS
Strengths
Git-push-to-deploy on your own server — like a mini Heroku
Dokku is an open-source Platform-as-a-Service built on Docker. Push code via git, and Dokku builds and runs it using Heroku-compatible buildpacks or Dockerfiles. Minimal dependencies.
Pricing
Free software. You pay for your VPS. Digital Ocean 1-click install available.
