AI agents are creating a new web access layer
GitHub, package, and operator evidence measure browser execution, live grounding, machine-readable interfaces, and controls protecting sites from agent traffic.
Early evidence; the market is not yet confirmed
66 implementations and packages reveal an asymmetric web layer: browser execution appears in 12.1% of the cohort, while live grounding appears in 4.5% and website-side crawler control in only 1.5%. Agent access is productizing faster than freshness, attribution, and origin protection.
Market snapshot
Comparable measurements from independent market surfaces.
Implementations and packages
Deduplicated and subject-filtered primary cohort.
Median repository stars
Calculated across repositories with at least one star.
Registry packages
Real npm and PyPI package records, not synthetic entries.
Latest-month npm downloads
Usage surface only; downloads are not equivalent to customers.
Search-match dynamics
Bars show monthly GitHub matches across browser agents, live grounding, and crawler controls; loaded counts are the deduplicated implementations used for feature analysis.
