Online Alarm Clock
Set an alarm quickly and easily. Choose your alarm time, pick a sound, and let your browser wake you up. No app install required.
How to Set an Alarm with This Online Alarm Clock
If you've ever needed a quick way to set an alarm without installing anything, you're in the right place. Alarm Click is a free online alarm clock that runs right in your browser. Just pick a time, choose one of ten sounds, and hit Set Alarm — that's it. Your browser handles the rest and plays the sound when the clock alarm goes off.
You can test any sound before committing, adjust the volume in settings, and use the snooze button if you need a few more minutes. There's also a Lights Off mode that blacks out the screen — handy when you're sleeping with your phone nearby and don't want the glow. Your last alarm set is saved locally so you don't have to re-enter it every morning.
Why Use an Online Alarm Clock?
Not everyone wants to download yet another app just to wake up on time. This alarm clock website works on any device with a browser — phone, laptop, tablet, whatever you've got. No account, no sign-up, no permissions to grant. Open the page, set an alarm, and you're done. It's an online alarm that respects your time and your privacy.
The online clock at the top always shows your exact local time, so you know your alarm is synced correctly. Whether you need a wake-up call at 6 AM or a reminder for a meeting at 3:30 PM, this alarm clock has you covered. And since everything runs locally, it works even with a slow connection — all you need is the tab open.
Alarm Clock vs. Timer — Which One Do You Need?
Here's the simple difference: an alarm clock goes off at a specific time on the clock (like 7:00 AM), while an online timer counts down from a duration you set (like 25 minutes). If you're thinking "wake me up at 8" — that's an alarm. If you're thinking "remind me in 10 minutes" — that's a timer.
Use this page to set alarm times for waking up, appointments, or any moment you don't want to miss. For study sessions, cooking, or workouts where you need a break timer or an exact timer, the timer page is what you want. You can also track elapsed time with the online stopwatch if you need to measure how long something takes.
Frequently Asked Questions
How does the online alarm clock work?
Set your desired alarm time and choose a sound. Keep this browser tab open, and the alarm will ring at the set time using your device's audio. If you need to time a shorter task instead, try the online timer.
Do I need to download anything?
No. Alarm Click works entirely in your browser. No downloads, installs, or sign-ups needed. All tools — including the stopwatch, timer, and world clock — run directly in your browser.
Will the alarm work if I close the tab?
The alarm requires the browser tab to stay open. Closing the tab will cancel the alarm. For date-based events, consider using the countdown tool to track time remaining.
Can I set multiple alarms?
Currently you can set one alarm at a time. Multiple alarm support is planned for a future update. In the meantime, you can use the timer alongside the alarm for a second timed reminder.
Does the alarm work on mobile?
Yes, the alarm works on mobile browsers. Make sure your phone is not in silent mode and the browser tab stays active.
What is the difference between the alarm and the timer?
The alarm triggers at a specific clock time (e.g., 7:00 AM), while the timer counts down from a duration you set (e.g., 10 minutes). Use the alarm to wake up or remember appointments, and the timer for cooking, studying, or workouts.
