Recover. Replay. Verify.
Durable sessions preserve the work. Verified replay checks recorded turns through the agent loop, without new model calls or tool execution.

work alive.
An experimental, distributed runtime for AI coding agents.
Recover durable sessions, verify recorded runs, and place work
across your own machines.
Get started
macOS + GNU/Linux ARM64 + x86_64curl -fsSL https://github.com/monocursive/ouroboros/releases/latest/download/install.sh | bashThen run ouro in your project. Runtime included. No Elixir or Rust required.
The runtime / four convictions
Your machines.
One agent runtime.
Put your fleet to work.
Place subagents by machine or toolchain tag. Native BEAM clustering tracks session ownership and each child’s Git worktree lease.
Give capabilities clear limits.
Extend through signed WebAssembly components with explicit host imports. Unknown imports are refused before a component can run.
Let it evolve. Keep your say.
Agents can forge new runtime capabilities. Replay evidence gates policy promotion; signing and deployment stay under your control.
