About this directory

How these entries are selected.

We review each repository’s purpose and source before adding it. The summaries describe what the project says it does; they are not independent performance or security endorsements. Star counts, language, license and last commit come from a dated GitHub snapshot and may have changed since then.

Stars sort this small, curated collection by popularity among the included repositories. They do not measure quality. Check each project’s README, license and current activity before using its code.
