Kamal

CLI deployment tool from 37signals for zero-downtime Docker container deployments.

Open source alternative to:

Kamal is a CLI deployment tool from 37signals (the makers of Basecamp and HEY) that deploys Docker containers to any server with zero-downtime rolling updates. Unlike dashboard-based PaaS platforms, Kamal takes a configuration-as-code approach — define your infrastructure in a YAML file and deploy with a single command. It requires no server-side agent, supports multi-architecture builds, and offers instant rollback. Perfect for developers who prefer terminal-driven workflows and want maximum simplicity with production-grade reliability.
