One row for each of the top 20 of 687 authors: a square marks each month with commits (bigger means more), and the line runs from their first to their last active month. Bot accounts are grey.
Contributors so far, month by month: each step up is a month in which someone made their first commit.
271 of 6,497 commits (4.2%) name an AI coding assistant: as their author, as a co-author, or in the line it signs with. In the last 12 months: 153 of 3,345 (4.6%).
These are lower bounds. An assistant that leaves no mark in the commit is not counted, and a mark does not say how much of the commit the assistant wrote.
| Assistant | Commits | As author | First commit | Last commit | |
|---|---|---|---|---|---|
| Gemini | 260 | 0 | 2025-07-04 | 2026-10-01 | |
| Jules | 11 | 0 | 2025-06-29 | 2026-02-16 | |
| GitHub Copilot | 1 | 0 | 2025-06-13 | 2025-06-13 |
A commit that names two assistants is counted under both.
Co-authored-by: line names an assistant, as Claude Code, Copilot, Cursor, Codex, Aider and others add when they commit for a person. A review bot whose suggestion was applied is named the same way.Assisted-by: or Generated-by: line names an assistant.Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.
Who made the most commits in each year and month, the runners-up, and how many people committed.
