Atuin Threads: All your agent sessions on every machine

Atuin Threads extends Atuin’s searchable, synced shell history to AI coding-agent sessions. The premise is that session logs preserve more useful context than command histories alone: prompts, reasoning, outputs, failed attempts, and the path to a solution. Yet these records are usually scattered across tools and machines, hard to search, and easy to lose. Threads lets users find sessions across devices, resume them in another agent or on another machine, and fork work without manually transferring context. It is available in Atuin 18.24 and supports Claude Code, Codex, Pi, Omp, and OpenCode, with more integrations planned.

Sessions are captured only with the user’s opt-in. Sync is end-to-end encrypted, and users can choose Atuin’s hosted service, run their own server, or keep data local. An MCP integration also lets agents search earlier sessions and reuse past decisions or investigations. Examples show agents drawing on abandoned onboarding experiments to avoid repeating work, tracing an avatar-upload outage through a prior investigation, and continuing a performance test across machines before sharing results back. The broader argument is that agent histories can become a durable record of work, helping individuals recover context and potentially enabling teams to share knowledge that never reaches code, tickets, or documentation. Opt-in team session sharing is in development.
