Your deploy stack is probably the worst-negotiated subscription in the whole company. Every server migration gets costed to three decimal places, but the Vercel bill that quietly creeps up a few dollars every month? Nobody consciously signs off on that. It just runs.
That's the gap Coolify walks into. It promises the thing a lot of teams have been quietly thinking: why pay $20 per seat or $25 per process to a US platform when a $6 server hosts the same app? The answer isn't "never" and it isn't "always." It's a calculation — and that calculation has one line item both sides conveniently leave off the landing page.
What Coolify is (and what it isn't)
git push, and seconds later your app is live on your domain, TLS cert included, on a server you own. That's the trick you'd credit Heroku with and never your own $6 VPS. Coolify delivers it.
Technically, it's a self-hosted PaaS, open source under Apache 2.0, positioned as an alternative to Vercel, Heroku and Netlify. You connect a server over SSH, attach a Git repo (GitHub, GitLab, Gitea, or self-hosted), pick a build pack (Nixpacks, Dockerfile, Docker Compose, or static), and Coolify does the rest: builds the image, runs the container, terminates TLS via Traefik with automatic Let's Encrypt certs, and serves the app. On top of that: 280+ one-click services, from databases to analytics to full apps, with built-in backup routines.
