Plasmo is an open-source framework and SDK for building browser extensions with React and TypeScript. It handles bundling, manifest generation, hot reloading, and publishing workflows for Chrome, Firefox, and Edge extensions.
Use cases
- build a chrome extension with react and typescript
- develop browser extensions without writing boilerplate manifest code
- hot reload a browser extension during development
- publish an extension to chrome web store and firefox addons
- migrate a manifest v2 extension to manifest v3
- create content scripts and popup UIs for extensions
When to choose
- you are starting a new browser extension project from scratch
- you want an integrated build, test, and publish pipeline for extensions
- you want React/TypeScript support with live reloading in extension development
When to avoid
- you have a simple extension that does not need a full framework
- you need fine-grained control over the bundler or manifest generation
- your extension targets browsers or platforms outside the mainstream Chromium/Firefox ecosystem
