Best / Self-hosted PaaS

Best open-source Self-hosted PaaS

The best open-source self-hosted PaaS in the c17.io catalog is Coolify (the published Heroku/Render/Fly.io stack), with Dokploy as the other Vercel/Netlify-shaped panel, CapRover if you want the older Docker+nginx git-push box, and Cloudron when you want an app store on a VPS. Coolify wants a Docker socket and a public IP — a VPS more than a single Railway service.

FAQ

Coolify or Dokploy?
Coolify is the published stack. Dokploy is the other Vercel/Netlify-shaped panel. Pick one control plane.
Why not Railway?
Railway is how c17.io ships. Coolify is the open-source control plane you run when you do not want a Heroku-shaped vendor at all. That is the stack FAQ.
Are these free?
Coolify and CapRover community code are Apache-2.0. Dokploy community is Apache-2.0; /proprietary is separate. Cloudron is the catalog product. You still pay a VPS. Template users never pay c17.
How do I deploy it?
Open /stacks/coolify-paas. Do not nest Coolify inside Railway — it wants the Docker socket on a VPS.
