Extinde documentation

Everything you need to build and ship browser extensions with Extinde. Start with the quickstart, then dive into topics like Manifest V3, permissions, content scripts, cross-browser compatibility, and publishing to browser stores.

Getting started

Sign in to Extinde, open the builder, describe your extension in plain English, and preview the generated extension in the built-in mockup. Download it as an unpacked folder or ZIP.

Prompting tips

The clearer your prompt, the better the output. Specify the browser action, the target sites, the UI (popup, sidebar, injected element), and the permissions your extension needs.

Manifest V3

Extinde generates Manifest V3 extensions by default so they work with the current Chrome Web Store requirements. Firefox and Edge get compatible manifests automatically.

Publishing

Follow the publishing guide to submit your extension to the Chrome Web Store, Firefox Add-ons, Microsoft Edge Add-ons, and the Extinde marketplace.
