Why?
Our current build tools for the web are 10-100x slower than they could be:

Major features:
- Extreme speed without needing a cache
- JavaScript, CSS, TypeScript, and JSX built-in
- A straightforward API for CLI, JS, and Go
- Bundles ESM and CommonJS modules
- Bundles CSS including CSS modules
- Tree shaking, minification, and source maps
