Coolify vs Miren

Coolify is an open-source, self-hostable deployment platform for websites, databases, web applications, and more than 280 one-click services. It builds each commit and deploys over SSH to a connected server. Projects can use Nixpacks, Railpack, Dockerfile, Docker Compose, static serving, or a prebuilt registry image. Push-to-deploy connections include GitHub, GitLab, Bitbucket, and Gitea, including self-hosted instances. One-click databases include PostgreSQL, MySQL, MariaDB, MongoDB, Redis, KeyDB, Dragonfly, and ClickHouse. Operations include pull-request deployments, scheduled tasks, shared environment variables, monitoring, S3-compatible database backups, and rollbacks. An API and MCP server let AI clients such as Claude and Cursor manage resources, deployments, logs, and restarts. Coolify runs only on Linux; the documented minimum is 2 CPU cores, 2 GB RAM, and 10 GB disk. Self-hosted use is free forever. Cloud costs $5 a month plus $3 server.

Miren is a container deployment platform for small teams running on Linux servers they control. It can build apps from source or run configured container images, then manage builds, scaling, routing, and TLS. Automatic source detection covers Python, Node, Bun, Go, Ruby, Rust, and Dockerfiles. Apps can declare services such as Postgres, MySQL, Valkey, Memcached, and RabbitMQ. Miren can create a separate preview deployment for each pull request, with configurable expiry; database previews are not supported. GitHub Actions works out of the box for CI/CD deployment, while GitLab CI and CircleCI need manual configuration. The runtime is open source under Apache License 2.0. An Always free plan has no seat limits or metered builds and includes a self-hosted runtime and Miren Cloud. Managed clusters have a 30-day free trial and cost $29 a month for the first six months, then 79 USD per month. Self-hosting requires users to manage their Linux server and its capacity.
