Urbit is a clean-slate OS and network for the 21st century.

Urbit OS is a reimagining of the operating system as an ‘overlay OS’.

It's a compact system for an individual to run their own permanent personal server on any Unix machine with an internet connection.

Urbit ID is a decentralized digital identity system. Your Urbit ID is a username, network address, and crypto wallet.

Urbit OS + Urbit ID are designed to work together as a single system, are completely open source, and 100% owned by the people who use them.
