Step by step
- Set your first alarm on this page and give it a clear label so you know which tab it is.
- Open a second browser tab to the same URL if you need another alarm for a different time.
- Pick from Classic alarm, Beep, or Soft chime in each tab, as custom audio files and streaming links are not supported.
- Keep all alarm tabs open and your computer awake until each one rings.

Related questions
Can I upload an MP3 or link Spotify as my alarm?
No. The sound is generated directly by your browser using three built-in tones (Classic alarm, Beep, and Soft chime) so it works offline once loaded.
How many alarms can I run in separate tabs?
You can open as many tabs as your browser handles comfortably, though keeping a few labeled tabs open is easiest to manage.
What is better if I need custom music to wake up?
Your phone's built-in clock app or a dedicated desktop alarm program is better if you want to wake up to songs or playlists.
