Contributor growth
Contributors so far, month by month: each step up is a month in which someone made their first commit.
AI-assisted commits
13 of 621 commits (2.1%) name an AI coding assistant: as their author, as a co-author, or in the line it signs with. 9 of them were made by an assistant under its own account. In the last 12 months: 13 of 179 (7.3%).
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 | Bar | As author | First commit | Last commit |
|---|---|---|---|---|---|
| GitHub Copilot | 11 | 9 | 2025-12-13 | 2026-04-12 | |
| CodeRabbit | 2 | 0 | 2025-12-11 | 2026-01-30 |
What is counted
- The author is an assistant's own account, such as the Copilot coding agent, Devin or Cursor's agent.
- A
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. - An
Assisted-by:orGenerated-by:line names an assistant. - The message has the line an assistant leaves in it, such as “Generated with [Claude Code]” or the link to a Devin or Codex session.
Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.

Cumulative lines added per author

Commits by organization
249 of 621 commits (40.1%) come from an address at 2 organizations, counted by the domain of the address and committed from by two people or more. Domains of one person (most often that person's own), personal mail providers, hidden noreply addresses and bots are counted apart, below.
The domain says where an address is, not who paid for the work: people commit from personal addresses on paid time, and from work addresses on their own.
