coollabsio/coolify

Self-hosted PaaS that keeps your Heroku-like workflow on your own servers — Coolify deploys apps, databases, and 360+ one-click services over plain SSH to any VPS, bare-metal box, or even a Raspberry Pi. It mirrors Heroku/Vercel/Netlify convenience—Git push deploys, PR previews, automatic HTTPS—while your configs and running resources stay independent of the tool itself. Good fit for teams wanting cloud-platform ease without losing control of infrastructure.

An open-source, self-hostable PaaS alternative to Vercel, Heroku & Netlify that lets you easily deploy static sites, databases, full-stack applications and 360+ one-click services on your own servers.
