related_applications
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The related_applications
manifest member is used to specify one or more native applications that are related to your web application.
It can be used with the prefer_related_applications
manifest member, which indicates a preference for installing either a related native application or your web application.

Description
A "related application" is a native application that provides functionality similar to your web app, often with additional features or better integration with users' devices.
The related_applications
manifest member lets you identify the platform-specific native applications that are related to your web app.
For example, consider you have a native Android app for your product available through the Google Play Store.
It provides the same core features as your web app and integrates better with the device's notification system.
You can use related_applications
to specify this native Android app in your web app's manifest file.
Some key points about the related_applications
member include:
-
It allows you to specify multiple related apps on different platforms, giving users options for native apps across various devices and operating systems.
-
It creates a unidirectional relationship between your web app and the specified native apps. The native apps are not required to reference your web app in return.
-
The data may be used by web crawlers to gather more information about the native apps related to your web app, potentially improving discoverability of these native apps.
-
When used with the
prefer_related_applications
member set totrue
, it enables browsers to suggest installing the related native app instead of your web app.Note: For Chromium-based browsers,
prefer_related_applications
should be set tofalse
or omitted to make your web app installable.
Examples
Specifying a related native application
This example shows how to specify a related native Android app in your web app's manifest file. It uses minimal information to identify the native app available on the Google Play Store:
{
"related_applications": [
{
"platform": "play",
"id": "com.example.app1"
}
]
}
Specifying related native applications on multiple platforms
If native versions of your web app are available on both Google Play Store and Windows Store, you can specify them in your web app's manifest file like so:
{
"related_applications": [
{
"platform": "play",
"url": "https://play.google.com/store/apps/details?id=com.example.app1",
"id": "com.example.app1"
},
{
"platform": "windows",
"url": "https://apps.microsoft.com/store/detail/example-app1/9WZDNCRFHVJL"
}
]
}
Specifying preference for installing a related native app
If you want to indicate to browsers that you prefer users to be given the option to install your native app, available on the Google App Store, instead of your web app, you can set prefer_related_applications
to true
. Browsers may then prompt users to install the native Android app instead of your web app.
{
"prefer_related_applications": true,
"related_applications": [
{
"platform": "play",
"id": "com.example.app1"
}
]
}
