A short, hand-curated list of Go libraries and tools that are actually worth using. Not a directory of everything that exists.
51 projects in 19 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 10 most-starred projects are shown first and the rest are folded under More. Archived repositories are removed automatically. Stars were last refreshed on 2026-09-22.

Bitsets, compressed bitmaps and other containers beyond slices and maps.
roaring - Compressed bitmaps for sparse or huge integer sets, with fast set operations and serialization.
bloom - Probabilistic set membership with Bloom filters sized from a target false positive rate.
bitset - Bitsets with set algebra, population counts, fast iteration over set bits and serialization.
Drivers, query builders, ORMs, migrations, embedded and distributed stores.
etcd - Distributed key-value store with Raft consensus, watches and leases, plus its client.

scan - Map database/sql rows onto structs, slices and primitives using struct tags.
duckdb-go - Official database/sql driver for DuckDB, the embedded analytical engine, with Appender and Arrow.
modernc.org/sqlite - SQLite translated from C, so database/sql gets an embedded database without cgo or a C toolchain.
Wiring applications together.
di - Dependency injection container with typed constructors, lifecycle hooks and scopes.
Linters, build tools, debuggers, code generators and terminal tools for daily development work.
fzf - Interactive fuzzy finder for the command line, with shell integration for files and history.
lazygit - Terminal UI for git with staging, rebasing, stashing and worktrees a keystroke away.
delve - Debugger with goroutine-aware breakpoints, core dump analysis and remote debugging over DAP.
air - Live reload that watches the tree, rebuilds and restarts the binary with a single config file.
golangci-lint - Linters runner that aggregates dozens of linters with caching, parallelism and a single config.
lfk - Kubernetes TUI with yazi-style Miller columns over the owner hierarchy, plus Helm and trivy.
Compilers, frameworks and drivers for microcontrollers, boards and the devices attached to them.
