Most-downloaded Agent Frameworks

65 tools in Agent Frameworks publish an npm or PyPI package from their own repo. Here they are by downloads over the last 30 days. Pydantic leads with 812.6M.

Counts from the npm downloads API and pypistats; a package only counts if its registry page links back to the tool's repo. Downloads include CI and mirrors, so read them as a usage signal, not a user count. Updated weekly.
