The record

Purpose: Miren is a container deployment platform for small teams that runs on Linux servers they control.
Deployments: Miren can build apps from source or run a configured container image, then manage builds, scaling, routing, and TLS.
Supported stacks: Automatic source detection supports Python, Node, Bun, Go, Ruby, Rust, and Dockerfiles.
Databases and services: Apps can declare services including Postgres, MySQL, Valkey, Memcached, and RabbitMQ.
Previews: Miren can create a separate preview deployment for each pull request.
CI integration: GitHub Actions works out of the box for CI/CD deployment, while other OIDC-capable systems such as GitLab CI and CircleCI require manual configuration.
Secrets: Miren stores secrets encrypted at rest and decrypts them into memory when needed; only its built-in cluster secret backend ships today.
Open source: The runtime that deploys and runs apps is open source under the Apache 2.0 license.
Limits: Self-hosting requires a Linux server, and users manage that server and its capacity themselves.
Audience: Miren says it is designed for small teams that want a flexible deployment platform without managing platform complexity.
Support: Miren directs users who need help to its Discord community for real-time support.
Company: The privacy policy identifies the company as Miren, Inc., doing business as Miren.
