the fast, batteries-included bundler for the web_
Built on C#/.NET with Ahead-of-Time compilation. No JIT to warm up, no runtime to install — netpack starts at native speed and stays there.
mean of 10 runs · npx netpack bundle src/small/index.html --minify
one graph in, one optimized output — resolved, transformed and written in a single pass
zero-config
Same entry point as Vite or Parcel — an index.html, or a JS file directly.
AoT compiled
No JIT warmup, no runtime to install. Native startup, every time.
auto import maps
Importmap entries become externals automatically; shared deps get wired in for you.
watch mode
Watches your filesystem, rebuilds, reloads the browser — no config needed.
npm-native
Install through npm, pnpm or yarn like any other bundler in your toolchain.
.NET native
Drop it into an ASP.NET pipeline as a post-process or asset optimizer step.
Most bundlers reach for Rust or Go once JavaScript gets too slow. netpack bets on C#/.NET instead: with Ahead-of-Time compilation, the CLI starts at native speed with no runtime install and no JIT to warm up.
The payoff is a language that reads easier than Rust and does more than Go, while still outrunning plain JavaScript tooling — even with a garbage collector still in the loop.
