A new kind of frontend build tool. Fast, lightweight, unbundled. ✌️

Snowpack

Snowpack is a modern frontend build tool for faster web development. It replaces heavier, more complex bundlers like webpack or Parcel in your development workflow.

Snowpack leverages JavaScript's native module system (known as ESM) to create a first-of-its-kind build system that never builds the same file twice. Snowpack pushes changes instantly to the browser, saving you hours of development time traditionally spent waiting around for your bundler.

Key Features

• Develop faster, with a dev server that starts up in 50ms or less.
• See changes reflected instantly in the browser.
• Integrate your favorite bundler for a production-optimized build.
• Enjoy out-of-the-box support for TypeScript, JSX, CSS Modules and more.
• Connect your favorite tools with third-party plugins.
