Foreman is a Procfile-based process manager that mirrors Heroku’s process model, making it easy to run multi-process applications in development and beyond. You declare your app’s processes (web workers, background jobs, schedulers) in a Procfile, and Foreman starts them together, streams multiplexed logs, and manages environment variables from .env files. It handles port assignment and process concurrency, so you can spin up multiple copies of a worker or web server with a single command. Exporters generate native service definitions (e.g., systemd/Upstart/launchd), enabling the same process topology to run under OS service managers in staging or production. Colorized, prefixed logs and simple signals (restart/stop) provide a clear operational experience for polyglot stacks. By codifying your app’s runtime composition, Foreman reduces “works on my machine” friction and keeps local setups close to deployment reality.
Features
- Reads a Procfile declaring multiple process types and commands to run those processes together in development environments
- Manages environment variables for the processes via .env or other mechanism so that all services share correct configuration
- Captures and streams combined logs/output from all processes, making it easier to see overall behavior locally
- Supports specifying which Procfile to use, custom procfile names (e.g. Procfile.dev)
- Cross-platform in development insofar as it works where Ruby environment is available
- Lightweight, simple, minimal dependency overhead, designed for development workflow rather than production process management
