Contributor timeline

One row for each of the top 20 of 1,920 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.

Contributor growth

Contributors so far, month by month: each step up is a month in which someone made their first commit.

AI-assisted commits

14 of 7,962 commits (0.2%) name an AI coding assistant: as their author, as a co-author, or in the line it signs with. In the last 12 months: 14 of 718 (1.9%).

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.

AssistantCommitsAs authorFirst commitLast commit
Claude1202026-01-132026-09-29
Cursor202026-03-032026-07-01
GitHub Copilot202026-03-172026-07-01

A commit that names two assistants is counted under both.

What is counted

Accounts and addresses are matched, not first names: a person called Claude, Devin or Jules is not an assistant.

Top author per year and month

Who made the most commits in each year and month, the runners-up, and how many people committed.

Cumulative lines added per author

Lines added over time by the top 20 of 1,920 authors; the top 5 are in color, the rest in grey.

Commits by organization

211 of 7,962 commits (2.7%) come from an address at 23 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.
