Native
ReleasedA monorepo of npm packages under @amigo-labs, written in Rust and compiled to native addons via NAPI-RS, with prebuilt binaries for every major platform. Most packages also ship a WASM build for browsers and bundlers.
Every call from Node.js into a native module pays a fixed cost for crossing the boundary, roughly 109 ns on modern Linux x64. The packages here are picked because their workload dwarfs that cost, and each one is benchmarked against its JavaScript alternative: the measured speedup decides whether a package stays, gets optimized, or is retired.

Each package is a drop-in replacement for a popular Node.js package. Where it is not a 100% drop-in, a MIGRATION.md says what differs.
Compiled with NAPI-RS for six targets: Linux x64 (glibc and musl), Linux ARM64, macOS x64 and ARM64, Windows x64. No build step on install, no compiler required.
Most packages ship a napi binary for Node.js and a WASM build for browsers and bundlers (Vite, esbuild, webpack ≥ 5, Rollup) in the same tarball. Conditional exports pick the right one; the import never changes.
argon2, jose and jwt stay Node-only on purpose — browser password hashing is an anti-pattern, and private signing keys must not ship to the browser.
No transitive dependencies — installing a package pulls in the package and its platform binary, nothing else.
Every package is benchmarked against the best JavaScript alternative and checked against the upstream package's behavior with conformance tests. A perf review classifies each one Green, Yellow, Red or Black.
Releases are built in CI and published to npm with provenance, so every tarball can be traced back to the commit and workflow that built it.
Every package is a drop-in replacement for its npm counterpart.
