A collection of IETF/WICG specifications and Go tooling for packaging websites into portable bundles, including Signed HTTP Exchanges (SXG), Web Bundles, and Isolated Web Apps signing. It lets resources that make up a site be bundled for offline sharing, with or without cryptographic proof of origin.

Use cases

bundle a website into a single file for offline sharing
create signed HTTP exchanges (SXG) for a site
sign web bundles with an integrity block for isolated web apps
generate and manipulate web bundle files from a CLI
verify that bundled resources came from the original origin
package subresources like JS modules, stylesheets, images, and fonts

When to choose

you need to implement or test the web packaging / SXG / web bundle specifications
you want to produce signed exchanges or signed web bundles for distribution
you're building tooling that reads or writes the web bundle format

When to avoid

you're looking for the webpack JavaScript bundler, which is a different project
you just need standard static site generation or JS bundling for deployment
you need a production-ready end-user application rather than spec tooling
