How we count
- Weeks with a release
- Weeks in the last 12 with at least one GitHub release, production deploy, merge to a production branch or version tag, whichever the team uses most.
- Review wait
- Median time from a pull request being ready for review to its first review by someone else.
- Time to merge
- Median time from opening a pull request to merging it. Automerges with no review are left out.
- Merged without review
- Share of merged pull requests that nobody other than the author reviewed.
- People and agents
- Everyone who committed, merged or reviewed in the last 12 weeks. AI agents that work under their own account are listed apart.
- By AI agents
- Share of merged pull requests opened by an AI agent, or of commits made by one, whichever is higher. Agents are Claude, Copilot, Codex, Devin and similar, plus a team's own bots whose pull requests read like an engineer's (varied titles, a written description), such as opencode-agent or posthog[bot]. Release, dependency and CI bots don't count.
- Reviewed by AI
- Share of merged pull requests that an AI reviewer commented on: CodeRabbit, Copilot, Greptile, Codex or a team's own review bot. Any bot that leaves review comments counts; approval-only, CI and code-scanning bots don't. AI reviews don't count toward review wait or merged without review.
