~2016.6.29 — The first public crowdsale of Urbit address space is now complete.
A personal server is a virtual computer which stores your data, runs your apps, and manages your connected devices.
Urbit is a secure peer-to-peer network of personal servers, built on a clean-slate system software stack.

A virtual city in the cloud
We believe controlling your own data, code and identity is the definition of digital freedom. We believe everyone needs digital freedom, not just a few hackers. We believe the only tool needed to solve this problem is a general-purpose server made for human beings.
Your urbit is your cryptographic identity, personal archive, application platform, and device hub. It's as easy to manage as an iPhone.
Read a longer overview, or check out our beliefs and principles.
In Urbit, network identities are cryptographic property, like Bitcoin. If Bitcoin is money and Ethereum is law, Urbit is land.
Urbit is designed to become a digital republic: a network of individually owned nodes with no central point of control. Like a well-planned city, the friendly network is decentralized but connected, safe but free.
Read more about the network architecture.
Your computer isn't yours unless you can run whatever software you want and switch without losing data. Imagine if you could replace the Facebook UI, or move your Evernotes to Google Docs.
Read more about the Urbit user experience.
An ordinary person can't manage a Unix server on the Internet. The Unix-Internet platform was a brilliant system, but it's almost 50 years old.
Urbit is a new clean-slate, full-stack server. It's implemented on top of the old platform, but it's a sealed sandbox like the browser.
Urbit remains young and unstable. Alas, it's not yet ready for end users. But it's feature-complete and ready for public development.
Read more in our whitepaper, developer docs, or development roadmap.
Our first public crowdsale was on June 28th 2016.
