Agent TrendsPreviewThis 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.

Codex is measured from the pull requests its cloud service opens, an estimate; an earlier signal from before November 2025 tells the same story.
Weekday vs Weekend
Across tracked agents, weekend PR volume runs 13.5% below weekdays, so coding agents are mostly a workday tool. The dip is an enterprise-versus-consumer tell: Devin falls 27.9% on weekends, while Jules barely moves.

Method
Daily points come from one measurement pass per public attribution class per day (created: single-day windows); weekly and monthly points over wider windows. Agents visible through their own bot or workflow (Copilot, Jules, Devin) are exact; agents measured through declared attribution (Claude Code, Cursor, Codex) are estimates that stabilize at daily granularity. Measurement classes are described on the methodology page.
