Coolify is an open-source, self-hostable platform-as-a-service that lets you deploy applications, databases, and services on your own servers as an alternative to managed platforms like Heroku, Netlify, and Vercel.

The tool solves the problem of vendor lock-in and high hosting costs by providing a self-hosted deployment system that works with any server you control via SSH. It manages VPS, bare metal, and single-board computers, automating application and database deployment while keeping all configuration on your own infrastructure. If you stop using Coolify, your running resources remain functional and manageable without the platform's automation layer.

Coolify suits teams and individuals who want control over their infrastructure, prefer to avoid recurring cloud platform fees, or need to deploy across heterogeneous hardware. The self-hosted model requires you to provision and maintain at least one server for Coolify itself and separate servers for your applications and databases. The project also offers a paid cloud-hosted version for those who prefer not to self-host, which includes high availability and managed infrastructure at comparable cost to self-hosting.

The project maintains a substantial user base, with almost all open issues coming from outside adopters reporting real-world problems rather than from the core team. Maintainers typically respond to new issues and pull requests within a day. Work in the issue tracker centers on bug triage and feedback collection, indicating active engagement with reported problems and user needs.
