Miren

What Miren is
Miren is a container deployment platform for small teams that runs on Linux servers they control. It can build applications from source or run a configured container image, and manage builds, scaling, routing, and TLS. Automatic source detection covers Python, Node, Bun, Go, Ruby, Rust, and Dockerfiles. Apps can declare services including Postgres, MySQL, Valkey, Memcached, and RabbitMQ. Miren creates a separate preview deployment for each pull request, with configurable preview 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 that deploys and runs apps is open source under Apache 2.0. The Always free plan has no seat limits or metered builds and includes the self-hosted runtime and Miren Cloud. Managed clusters cost $29.00 per month for the first six months, then $79 per month, and include a 30-day free trial. Self-hosting requires a Linux server, whose capacity users manage themselves. Miren, Inc., doing business as Miren, directs users who need help to its Discord community.
