Lunx vs major build tools
Where Lunx sits in the 2026 market, with measured numbers. We say where we win and where we do not.
v1.2.0
Market seat
Lunx is a challenger built on Rolldown + Oxc: one tool for SPAs, meta-frameworks, libraries, Module Federation and security checks, in one package. Vite owns default DX; Rspack owns webpack migrations; Turbopack owns Next.js.
Quick verdict
| Field | Type | Default | Description |
|---|---|---|---|
| vs Vite | Ahead | — | Faster dev boot (243 vs 389 ms), HMR (151 vs 161 ms) and builds (583 vs 829 ms cold) on a 2,000-component app, slightly smaller output, and Vite plugins, Storybook and Vitest run on lunx. Lunx adds federation, security checks, PWA and Electron built in. |
| vs Rsbuild / Rspack | Closest MF rival | — | Lunx is faster in dev at scale (HMR 151 vs 440 / 656 ms), builds faster and ships ~6% less gzip JS. Rspack keeps webpack loader compatibility. |
| vs webpack | Win on speed/config | — | About 17× faster dev boot and 16× faster warm build on the large app. webpack keeps the deepest loader ecosystem. |
| vs Parcel | Win at scale | — | Parcel is mature zero-config; at 2,000 components it boots in 4.5 s vs lunx's 0.24 s. |
| vs Turbopack | Different market | — | Turbopack is Next-only. In a Next.js project lunx runs next dev / next build. |
| vs esbuild / Bun | Different product | — | They bundle several times faster, and Bun's output is 3–4% smaller, but neither has an HMR dev server or framework support. Lunx is a full CLI. |
USP we compete on
- One engine for everything: SPAs, 12 meta-frameworks, libraries and servers on Rolldown + Oxc
- Module Federation without webpack, compatible with webpack containers, dev and build mixed
- Security CLI (secrets, CVE, SBOM, SRI) in the same tool
- Lean and cached: 1.1 MB package; unchanged projects skip the build
Where we are behind
- Bun's output is 3–4% smaller (it tree-shakes inside CommonJS dependencies)
- Toolchain breadth: no built-in lint, format or monorepo task runner yet (Vite+ has them);
lunx testis basic, Vitest runs throughlunx exec vitest - Next.js, Gatsby, Docusaurus, RedwoodJS and Stencil still run their own CLIs
- Ecosystem maturity: Vite and webpack have years of production use
