Risks

Interoperability and Compatibility

This feature is new to the web and web apps that do not opt in will not be affected because any additions to the web app manifest will be optional. Browser behavior will also not be affected if there are no installed apps that opt in. Browser that do not support this feature will not be adversely affected by new members in the web app manifest.

Gecko: No signal

WebKit: No signal

Web developers: Positive (https://techcommunity.microsoft.com/t5/discussions/click-url-to-open-pwa-automatically/m-p/2192994)

Security

https://github.com/WICG/pwa-url-handler/blob/main/explainer.md#security-considerations

Goals for experimentation

Allow third party developers to use the API and provide feedback.

Ongoing technical constraints

None

Debuggability

Debug functionality will be added to the the DevTools(F12) Application pane.

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Supported in the browser on Windows, Mac, and Linux. Integration with OS features will vary.

Is this feature fully tested by web-platform-tests?
