Urbit is a personal server stack built from scratch, consisting of an operating system kernel (Arvo), a virtual machine runtime (Vere), and a decentralized identity layer (Azimuth). It forms a general-purpose peer-to-peer network where each running instance, called a 'ship', communicates directly with other ships.

Use cases

• run my own personal server with full data ownership
• join a peer-to-peer network without big tech intermediaries
• build apps on a clean-slate operating system with its own language
• get a decentralized identity for online communication
• self-host chat and social software on my own machine
• explore an alternative computing stack built on a minimal VM

When to choose

• you want full control over your personal data and server
• you're interested in alternative operating systems and novel programming languages like Hoon
• you want a decentralized identity and peer-to-peer networking in one stack
• you want to self-host applications with minimal maintenance

When to avoid

• you need mainstream tooling, libraries, or ecosystem compatibility
• you want a quick conventional web server or VPS setup
• your team already works in standard languages and infrastructure
• you're unwilling to learn Hoon/Nock or manage a persistent always-on process
