First-class support for React, Svelte, and Vue

Bring your existing components and Plasmo will automatically mount them onto the extension for you.

​

Style Leakage Prevention

Plasmo will automatically create a shadow DOM, preventing styles from leaking from and to the page you're extending.

​

Live-reloading

Plasmo will automatically reload your extension when you make changes to your code. No more hitting the reload button.

​

React HMR

Plasmo injects into your React app and enables HMR, allowing you to see changes to your components without reloading the page

​

Target-specific entries

Subtitute browser-specific logic with eases by adding the browser's name: popup.firefox.tsx, .env.arc, etc.

​

Environment variables

With built-in .env support and dead-code elimination, you can easily target specific browsers with different logic.
