What is Coolify?
A self-hostable platform that gives you cloud-style deployment of apps, databases and services on your own servers, managed over SSH and free of vendor lock-in.
Is Coolify free to self-host?
Yes. The self-hosted version is Apache 2.0 with nothing behind a paywall. On AWS you pay for the instance and any Meetrix software fee shown on the listing.
What can I deploy?
Docker apps, static sites, background workers, PostgreSQL, MySQL and Redis databases, and one-click services, with Git-based CI/CD, secrets and cron jobs.
When should I leave Vercel or Netlify for Coolify?
When bandwidth or per-seat costs grow faster than revenue, or you need long-running processes and databases that do not fit a serverless model. You give up their global edge network.
Why does my app show 502 Bad Gateway?
Usually Port Exposes does not match the port your app listens on, or the app is bound to 127.0.0.1 instead of 0.0.0.0.
Do I need Kubernetes?
No. Coolify runs on plain Docker, and a single server is enough.
Which instance size should I choose?
t3.medium is the recommended starting point. Size up for more or heavier apps.
How do I upgrade?
Back up your server data, remove the old stack and launch the new version from AWS Marketplace.
