Inside the product
What you can actually do with it.
The core product capabilities, grouped around the work they enable.
Extension framework
Plasmo mounts React, Svelte, and Vue components into browser extensions and supports declarative extension development.
Development runtime
The framework provides live reloading and React hot module replacement while extension code changes.
Itero delivery tools
Itero can deploy extension builds to testers through GitHub integration and manage production web store deployment credentials.
Typical workflow
Create an extension with the Plasmo Framework and develop its interface and browser-specific behavior in a single codebase. Use Itero to deliver builds to testers, then manage browser store publishing when the extension is ready for production.
