Canary (YC)

Canary provides verification infrastructure for AI code generation tools. When Claude, Codex, or other coding agents generate changes, Canary deploys agent swarms to investigate potential failures and test suspected runtime bugs in isolated sandboxes. The system uses changesets, intended behavior, and team knowledge to validate code before deployment.

Developers can integrate Canary via CLI (npm i -g @runcanary/cli) to verify AI-generated code on their repositories. The tool focuses on catching runtime bugs and validating behavior through automated testing in remote environments.
