Webui Web App

WebUI Web Apps

Installable WebUIs

Chrome WebUI can be installed as web apps if they are developed for that purpose (e.g. have valid manifests). Please consult with the Web Apps & Security teams if you consider making a WebUI installable. So far the only such app is the PasswordManager WebUI available at chrome://password-manager.

Restrictions

WebUI web apps should have a clear and limited purpose and scope, and do not access other Chrome resources. For example, a Password Manager app should not let the user access the browsing history inside the app. To guarantee that, a navigation throttle exists that opens all navigations from WebUI web apps in a new browser tab, instead of opening an in-app CCT.

*This does not apply for ChromeOS system web apps, which might have their own navigation rules.
