krausest/js-framework-benchmark AI coding statistics: 7.7%

of 352 commits in February–September 15, 2026 were committed by an AI agent — a floor, not an estimate
7.7% agent · top contributor 33.3%9 contributors
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

27assisted
0autonomous

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.

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 window510
Merge commits removed−158
CI / dependency bots removed−0
Considered352

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