Polaris: A Native macOS App for Kamal

Polaris is a native macOS desktop app that provides a graphical interface for Kamal, an open-source deployment tool created by the Rails core team (37signals). Kamal lets developers deploy web applications to their own servers using containers (Docker) — an alternative to using cloud platforms like Heroku or Fly.io that abstract away the underlying server. Until now, Kamal has been a command-line-only tool; Polaris wraps it in a visual UI, making it easier to manage deploys, view logs, and monitor server status without touching the terminal. This matters because it lowers the barrier for developers who prefer GUI tools, and signals growing demand for self-hosted deployment workflows outside the big cloud providers.
