Notification Test
A free end-to-end test for desktop and browser notifications. This is the tool for the "my Teams alerts never pop up" or "browser notifications do nothing" ticket. It checks that the Notification API exists, requests permission (a browser prompt may appear), then fires one real test notification to your desktop and confirms it was created without error. When permission is granted but nothing appears, it explains the usual cause: the operating system is suppressing it (Windows Focus Assist, macOS Do Not Disturb) or the browser tab is focused.
Read the Notification Test guide for help reading the verdict or fixing a blocked or suppressed notification.
