Packaging and Publishing for Multiple Stores
Learn how to bundle a single extension codebase and submit it to both the Chrome Web Store and the Microsoft Edge Add-ons store.
Why Publish to Multiple Stores
Once your extension works across browsers, the next step is distribution. The two largest Chromium stores are the Chrome Web Store and the Microsoft Edge Add-ons store.
Publishing to both maximizes reach with almost no extra code, since both consume the same Manifest V3 package.
One Codebase, Two Packages
You usually ship the same ZIP to both stores. Small differences (like minimum versions or store-specific keys) can be handled with a build script.
- Keep one source tree
- Produce store-specific builds via scripts
- Avoid maintaining forks
