About the data +

Live GitHub signals include current repository metadata for linked projects. The Index uses the last verified source data available.

Edition snapshots cover figures from sources that cannot be refreshed reliably. Those values are labeled so you can verify them at the original source.

Curated entries are selected for primary documentation, ecosystem relevance, or practitioner contribution. These pages remain a dated Index edition.
