DeployOS vs Coolify

Yes — DeployOS's discovery flow scans a server for running Docker Compose projects (including ones Coolify manages) and can adopt them as managed apps without redeploying, so you can trial DeployOS against your existing Coolify setup before committing.

No, DeployOS is closed-source and commercially licensed. If open source is a hard requirement for you, Coolify is the better fit on that basis alone.

Coolify is free. DeployOS is a one-time purchase ($0/$49/$79). If budget is the only variable, Coolify wins outright — the DeployOS case is about not running an extra always-on service and getting a native app, not about being the cheaper option.

In January 2026, security researchers disclosed 11 critical vulnerabilities in Coolify's control-plane dashboard (CVSS up to 10.0, an estimated 52,000+ exposed instances) — authentication bypass and remote code execution against the always-on service that manages your server. Responsible disclosure is how this is supposed to work, and it's a genuine credit to that process that these got found and reported — but it's also a concrete example of the risk that comes with running a management dashboard with root-level Docker access, reachable from the internet, on your production server. DeployOS has no equivalent surface to patch: no dashboard, no listening service, nothing running on your server between deploys.
