About this product
Building a browser extension should not start with an afternoon of reading about Manifest V3 service workers. Chrome Extension Shuttle gives you a TypeScript project with Vite hot reload, a popup, an options page, a content script and a background service worker, all talking through a small typed messaging layer.
Storage is wrapped in a typed helper that syncs settings across devices, and the build produces separate Chrome and Firefox packages from one command. A checklist covers the store listing, privacy disclosures and the permission justifications reviewers ask for.

- Accessibility
Jonas builds design systems for product teams and has a long-standing grudge against inaccessible dropdowns. He designs and codes the UI kits, the Next.js starter and the icon set, testing every component with a keyboard and a screen reader before it is released. He believes a component library is only finished when the documentation is.
