Product Overview

Plasmo is an end-to-end platform specifically built for browser extension development, with the goal of making the entire process of building, testing, and publishing extensions incredibly simple and efficient.

Plasmo provides a complete toolset, from framework to testing environment (TestBed), to publishing (Publisher/Browser Platform Publisher), covering the entire lifecycle of extension development. You can use it to quickly start new extensions, write popups, content scripts, background scripts (background Service Workers), tab pages, and other common components, while supporting hot-reloading and React HMR for instant feedback during development.

Tech Stack Features

In terms of technology stack, Plasmo core supports TypeScript + React, and also supports Vue or Svelte. It includes built-in modules like storage and messaging APIs, simplifying communication between different scripts (such as popup, content script, or background script) and state management challenges. The management of manifest.json is also highly abstracted - developers typically don’t need to write manifests manually, but instead generate them automatically through configuration or source code conventions.
