Free Online Alarm Clock

This free online alarm clock lets you set a reliable alarm right in your web browser. No app to download, no sign-up required — just pick a time, choose your favorite alarm sound, and you're all set. Keep this tab open and your alarm will ring on time.

How It Works

Use the up and down arrows to select the time you'd like to be woken up. For example, if you want to wake up at 6:30 AM, set the hour to 06 and the minutes to 30. Then choose one of eight alarm sounds — from a classic bell to a rooster crow — and press Set Alarm. A live countdown will show exactly how long until the alarm rings. When your wake-up time arrives, a full-screen alert will appear with options to stop or snooze for 5 more minutes.

Features

Works entirely in your browser — no downloads or installations needed.
Eight unique alarm sounds including classic, digital, gentle, rooster, and more.
Easy time selection with up/down arrow buttons.
Snooze button adds 5 extra minutes if you need a bit more rest.

Tips

Keep this browser tab open for the alarm to work. On mobile devices, make sure your phone isn't on silent mode so you can hear the alarm sound. For the best experience, tap any sound button first to allow audio playback in your browser.
