Notification Tester

Check whether your browser can show notifications and what they look like on your system. The tester shows the current permission state, asks for permission only when you press the button, and sends a notification with your own title and message, optionally after a short delay so you can switch away and see it arrive in the background.

Features and Limitations

Features

Shows support and permission state (granted, denied or not decided).
Custom title, message, delay, keep-on-screen and silent options.
Event log showing when the notification was shown, clicked, closed or failed.
Specific help for denied permission and system-level Do Not Disturb or Focus modes.

Limitations

This tests local notifications created by the page. It does not test push messages from a server, which need a service worker and a push service.
If the operating system blocks notifications for the browser (Focus Assist, Do Not Disturb), the browser may report success while nothing appears.
Some mobile browsers only allow notifications from installed web apps; they are reported as unsupported here.
Results are computed in your browser; nothing you enter is sent to a server.

Frequently Asked Questions

I clicked Block by mistake. How do I allow notifications again?

Click the lock or site-settings icon next to the address bar, set Notifications to Allow, then reload the page. Browsers do not let a page ask again once you have blocked it.

The log says the notification was shown, but I saw nothing. Why?

Your operating system is probably suppressing it. Check Focus / Do Not Disturb mode and the notification settings for your browser in Windows Settings, macOS System Settings or your phone's settings.

Why does my phone browser say notifications are unsupported?

Android Chrome only allows notifications through a service worker, and iOS Safari only for web apps added to the home screen. Desktop browsers support the simple notifications used here.

Will this site send me notifications later?

No. The page only creates the test notifications you request while it is open. It has no server push and does not store your permission choice; your browser does.
