What is PhreshOS?
PhreshOS is an open-source, self-hosted platform that runs web applications on your own hardware. It provides a browser-based desktop environment where each application gets its own managed server process, shared authentication, inter-app communication, storage (files, key-value, SQLite), and granular permissions. The system is designed for both human users and AI agents to use the same apps simultaneously. Installation is via npm with the @phreshos/cli package, requiring Node.js 24.15+ and optionally Bun for development. The desktop runs on port 4300 by default. PhreshOS is currently experimental and not recommended for production use.
