PhreshOS is an experimental self-hosted 'OS for web apps' that lets you build programs with web technologies and run them in a browser-based desktop environment. It provides authentication, inter-program communication, permissions, and storage, with AI agents able to interact via CLI and SDKs. The project is ambitious and well-architected, though not production-ready yet.

Target audience: full-stack developers, web developers, self-hosters, AI agent developers
