Open source

The evidence layer for coding agents.

Outerlayer is an open-source platform for coding-agent fleets. It traces every agent session, ties it to the pull request it produced, and shows what merged, what got reverted, and what it cost — then points you at the few mistakes worth fixing.

Works from your first Claude Code session
