Create a Chrome OS web app for any website

Chrome OS has a growing number of web applications available in the Chrome Store. However if there isn’t one available but you would like a icon for a web app in your App Drawer the following instructions will guide you through creating your own.


This example creates a web app for the TalkTalk email client.


1. Create a folder in “Downloads” to store the Web App.


2. Create a plain text file called manifest.json with the following text (I used ShiftEdit).



    "name": "Talk Talk Mail",

    "description": "Access Talk Talk Email Full Screen",

    "version": "10.0.0",

    "manifest_version": 2,

    "icons": {

        "128": "icon_128.png"


    "app": {

        "urls": [“”],

        "launch": {

            "web_url": ""





Substitute the name, description and version to match your application. Change the URLs to match the website your app is for.


3. Create a 128 x 128 png file called icon_128.png, this will be the icon displayed in the App Drawer. Put this in the same folder as the manifest.json file.


4. Add the web app as an extension to Chrome (More Tools > Extensions). Make sure developer mode is selected and the top of the extensions page. Click “Load unpackaged extension”, navigate to your Web App folder and click open.


5. All being well your extension will appear in the list and the web app will appear in the App Drawer.


Note: These extension cannot be published on the Chrome Store unless you own the domain the URLs in the manifest.json file point too.
