A short, hand-curated list of Go libraries and tools that are actually worth using. Not a directory of everything that exists.
46 projects in 17 categories. Every entry is added by a human through a pull request and checked against the entry rules by CI. An entry earns its place by covering something no listed project does, or by doing it better. Within each category the 5 most-starred projects are shown first and the rest are folded under More. Archived repositories are removed automatically. Stars were last refreshed on 2026-09-17.
