About the Online Alarm Clock
This free online alarm clock rings at any time you set — with a sound and a browser notification — right from your browser. Add one or more alarms, give each a label, and a live clock shows the time. When an alarm goes off you can snooze it for 5 minutes or stop it. There's even a fullscreen clock for a bedside or desk display.
There's no app to install and no sign-up. Your alarms are saved in your browser, and nothing is uploaded.
Keep this tab open
For the alarm to ring, keep this tab open. You don't have to stay on it — switch to another tab, open other windows, or minimize your browser, and the alarm will still go off. Just don't close the tab (or the browser), and try to keep your device awake.
