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

894 conformance fixtures pass against the live Tailwind oracle; 186 byte-sensitive snapshots confirm formatting matches.

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

Real-world project: horizon-tailwind-react (2,551 candidates, 706 rules)

Synthetic smoke project (734 candidates): 195 ms → 5 ms (38x).

Quick start

bash

npm install -D vite-plugin-galeforcecss

// vite.config.js
import { defineConfig } from 'vite'
import galeforcecss from 'vite-plugin-galeforcecss'

export default defineConfig({
  plugins: [galeforcecss()],
})

Status

Alpha. Zero semantic diff against the official Tailwind v3 oracle on seven real-world projects, 894 conformance fixtures, and 186 byte-sensitive snapshots. APIs are stable for the documented surface but may change before 1.0.

GaleforceCSS is not an official Tailwind Labs project.
