apache/superset AI coding statistics: 53.7%

of 2,831 commits in February–September 15, 2026 were committed by an AI agent — a floor, not an estimate

org-wide

Adoption is broad. Many contributors are committing agent-authored work, which is what a real organisational rollout looks like.

02Drivers

What shapes this result

Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.

Assisted or autonomous

1408assisted

111autonomous

Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached. Across the whole index, 96% of agent commits are assisted.

04Method

What entered the denominator

The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.

Exclusion ledger

Commits in window	4,226
Merge commits removed	−0
CI / dependency bots removed	−1,395
Considered	2,831

Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.
