Chrome Web Store Apps



This page describes how you publish a new extension or theme ('item') to the Chrome Web Store.

To publish updates to an existing item, or to update the percent rollout, see Updating your Chrome Web Store item. To learn about group publishers, see Set up group publishing.

Before you publish an extension, you need to load it locally and test that it works, as described in Hello extensions. Make sure that it runs correctly and that all its functionality works as you intend.

To publish your item to the Chrome Web Store, follow these steps:

If you already host your item in Google Play and you want your Chrome Web Store listing to show an 'Available for Android' link, your item must have the same name as your Google Play listing, and both items must be owned by the same developer account. Google removed apps from its Chrome Web Store in 2017, but users still can take advantage of many extensions available through the store. Unlike standalone apps, extensions add functionality to a web browser or serve as convenient links to websites and other online tools. The Chrome Web Store (CWS) is Google's online store for its Chrome web browser. As of 2019, CWS hosts about 190,000 extensions and web apps. CWS was publicly unveiled in December 2010, and was opened on February 11, 2011, with the release of Google Chrome 9.0. A year later it was redesigned to 'catalyze a big increase.

  1. Create your item's zip file
  2. Create a developer account
  3. Upload your item
  4. Add assets for your listing
  5. Submit your item for publishing

Apps install quickly, without restarting your computer or browser. Your apps are always available when you sync apps across multiple computers. Apps are always up-to-date because they are hosted on the web. Apps won’t crash your computer. If you have trouble with an app, close its tab. You can easily find and open the app using app launcher.

We'll go into detail about each step below.

Create your item's zip file #

To upload your item, you need to create a ZIP file that contains the files for your extension. The item's manifest file must be included, and it must specify at least the following fields:

  • 'name':—Displayed in the Chrome Web Store and in the Chrome browser
  • 'version':—The version of the metadata, incremented
  • 'icons':—An array specifying the icons your item uses

Your zip file may also include other images and any files that the item requires. The contents of the ZIP file and manifest depend on the specifics of your item; see Extension files for more details.

Tips:

  • Set the initial version number in the manifest to a low value, such as 0.0.0.1. That way, you have room to increase the version number when you upload new versions of your item. Each new version that you upload to the Chrome Web Store must have a larger version number than the previous version.
  • If your item uses Native Client, you can structure your application directory hierarchy and ZIP file in a way that reduces the size of the user download package. For details, see Reducing the size of the user download package.

Before you upload your item, you'll be asked to pick a developer account to own your items. Instead of your personal account, we suggest using a dedicated account.

Create a developer account #

Before you can publish on the Chrome Web Store, you need to register as a Chrome Web Store developer. We suggest using a new account just for your item instead of your personal account.

On your developer account, the email address field is required. You cannot publish items if this field is blank.

If you already host your item in Google Play and you want your Chrome Web Store listing to show an 'Available for Android' link, your item must have the same name as your Google Play listing, and both items must be owned by the same developer account. To transfer your Chrome Web Store item to a different developer, submit this form.

Upload your item #

To upload your item, use the Chrome Developer Dashboard.

If you need the item ID to complete your item's code, then you need to upload the item while you're still writing its code. Otherwise, you can wait until the item is finished. You can upload your item many times before submitting it for review.

  3. Click the Add new item button.

Deferred publishing option #

The confirmation dialog shown above also lets you control the timing of your item's publishing. If you uncheck the checkbox, your item will not be published immediately after its review is complete. Instead, you'll be able to manually publish it at a time of your choosing once the review is complete.

Review of submitted items #

After you submit the item for review, it will undergo a review process. The time for this review depends on the nature of your item. See the FAQ on review times for more details.
