GaleforceCSSTailwind v3 at Rust speed

Drop-in replacement for Tailwind v3 — same config, same output, 23x faster builds.

23x faster builds

10 ms vs 246 ms on a 2,551-candidate real project. Pure compute hits 1.2 ms — 0.4 µs per candidate.

Verified Tailwind v3 parity

941 conformance checks pass against the live Tailwind oracle, including 501 cases ported from upstream's own suite and 186 byte-sensitive snapshots.

Incremental HMR

Per-file candidate cache. Content-file edits trigger a single-file scan and selective recompile; no-op edits produce zero traffic.

Full Tailwind v3 surface

All utilities, all variants, @tailwind / @layer / @apply / theme() / @screen, plugins (addUtilities, matchUtilities, addVariant, …), arbitrary values, opacity modifiers.

Benchmarks
