LICENSES

Crates by declared license

This page lists every distinct license value rendered on the directory’s 20,086 individual crate pages, each listed once with the number of those pages carrying it, grouped by the value with runs of whitespace collapsed to a single space. Every license links to its own group page.

Data as of 2026-07-25 (crates.io database dump, timestamp 2026-07-25T02:00:36Z). Source: crates.io · db-dump.tar.gz · methodology & corrections. Each value is the crate’s own rendered License field, not a reclassification.
