    Online Alarm Clock

    Set browser alarms that ring on time

    Create one-time or repeating alarms with custom sounds, snooze, and optional notifications - all in your browser, with no install and no account.

    How it works

    1. 01

      Pick a time

      Choose the hour and minute, add an optional label, and decide whether it repeats once, daily, on weekdays, or on custom days.

    2. 02

      Leave the tab open

      Alarms run in this browser tab using your device clock. Keep the page open (or pinned) so the sound and notification can fire.

    3. 03

      Dismiss or snooze

      When it rings, stop the alarm or snooze for five minutes. Enabled alarms restore automatically after a refresh.

    Why use an online alarm?

    Handy when you are at a computer without a phone nearby, need a quick one-off reminder, or want several labeled alarms with different sounds - without installing another app.

    What you get

    • Multiple alarms

      Save as many labeled alarms as you need; toggle each one on or off independently.

    • Flexible repeat

      Once, every day, weekdays, weekends, or pick custom days of the week.

    • Custom sounds

      Classic, chime, digital, or soft tones - preview before you save.

    • Snooze

      Hit snooze for five more minutes without rewriting the alarm.

    • Notifications

      Optional browser notifications and vibration when the alarm fires.

    • Stays on device

      Everything is stored locally in your browser - no account, no cloud sync.
