How current is this data?

The last sync completed 3h ago. Every field shows its own observation date, because fields refresh independently.

Agent engineering frameworks

Q: Where do these figures come from?

Each field is synced from the project's own registry and carries the source that reported it and the moment it was observed. Values that fail validation are withheld rather than shown.

This directory tracks 18 open-source agent-engineering frameworks across GitHub activity, package downloads and release cadence. Every figure carries the source that reported it and the moment it was observed. Values that fail validation are withheld rather than shown, and the last verified snapshot stays on the page until a clean sync replaces it.
