WXT VS Plasmo

Posted on:February 24, 2024 at 12:10 PM

Browser extensions are always a hot topic in the web development community. And of course, just like React and Vue in the web development world, there are also two popular frameworks for browser extension development: WXT and Plasmo. In this post, I will compare these two frameworks and help you choose the best one for your next browser extension project.

What is WXT

WXT is a free and open source framework for building web extensions in an conventional, intuitive, and safe way for all browsers.


What is Plasmo

Plasmo is an all-in-one platform that makes it easy for browser extension developers to create, test, and publish amazing extensions.



Both of them are great frameworks for browser extension development, but they have their own pros and cons. Here are some key points to consider when choosing between WXT and Plasmo:

Frontend Framework Support

WXT supports all the frontend frameworks while Plasmo only supports React, Vue and Svelte. If you are using other frontend frameworks like Angular or Ember, WXT is the best choice for you.

But if you’re using React, Vue or Svelte, Plasmo is a great choice because it has first-class support for these frameworks. For example, WXT doesn’t support your file as a .vue or .svelte file, but Plasmo does.

Messaging API

WXT has no built-in support for the messaging API yet since it’s still in the early stage of development. But Plasmo has built-in support for the messaging API, which makes it easier to communicate between different parts of your extension.

Automatic Publishing

Plasmo has built-in support for automated deployment via BPP, which makes it easier to publish your extension to the Chrome Web Store, Firefox Add-ons, and other platforms. WXT doesn’t have built-in support for automated deployment yet, but it’s on the roadmap.

Another Option for Starting with a Boilerplate

Besides WXT and Plasmo, you can also start with a boilerplate. I’ve created one open-source boilerplate for browser extension development, which is based on Vite, React, TypeScript and Tailwind CSS. You can use it as a starting point for your next browser extension project. My AI Group Tab is built on top of this boilerplate.
