WXT alternatives

2 Chrome Extension kits compared with WXT on price, license, framework and features.

About WXT

WXT (Vite, free) - Vite-powered browser extension framework with file-based routing and Nuxt-style auto-imports. Best for: Developers who want Vite's dev experience for extension work and need to target Chrome, Firefox, and Safari from one codebase without hand-writing manifest.json.

The usual reason to look elsewhere: you're locked into Plasmo's React-first APIs already, or you need a hosted build/publish service rather than a self-managed CLI framework.

Best for: React/TypeScript teams that want a batteries-included, opinionated framework with built-in messaging and storage APIs, plus optional hosted testing/publishing add-ons.

Compared with WXT

  • Freemium, where WXT is free.
  • Built on React rather than Vite.

Your extension's UI is built in Vue or Svelte as the primary framework, or you'd rather build on Vite than a Parcel-based toolchain.

Extension.js

React · Free · 5,203 stars

Best for: Developers who want a single codebase that targets Chrome, Firefox, Edge, and (limited) Safari with genuinely zero build configuration, regardless of which UI framework they pick.

Compared with WXT

  • Built on React rather than Vite.

You want a framework with a large, established plugin/module ecosystem already built up - Extension.js is newer and smaller than WXT or Plasmo.
