PHP Coding AgentsPreviewThis index is in active development: we are still adding agents, refining attribution signatures, and verifying data against sources. The date in the header is when key figures were last re-checked. Numbers can move as coverage improves.
In PHP repos on public GitHub, 49,941 PRs carried an agent mark between 2026-07 window start and end, which is 18% of all PHP PRs. Claude Code does the most of it.
Coverage: tracks Claude Code, Codex, Copilot agent, Cursor, Devin, and Jules. Codex is measured through hosted task metadata, checked against sampled PRs. Gemini CLI and other terminal agents work through the developer's own identity, leaving nothing public we can detect yet, so they cannot be measured here. We are expanding coverage. Methodology
