[](https://evalaitools.com/tools/langfuse/)How this is measured: commits on the repository’s default branch counted through the GitHub API, the last 91 days against the same 91 days a year earlier; archived flag and licence from the repository; README checked daily for maintenance notices. Commit counts measure activity, not quality, and we have not tested this tool ourselves for this page.
