Set an online alarm clock in seconds. Choose a time, pick a sound, and VClock wakes you up right in your browser — free, accurate and with no sign-up or download.
Three steps, about ten seconds, and no account required.
Type the hour and minute you want to be woken up and choose AM or PM. You can also add a short label such as "Meeting" or "Take medicine" so you remember why the alarm is there.
Select from six built-in alarm sounds — a gentle chime for a soft wake-up or a loud siren when you really cannot oversleep. Each sound previews instantly when you select it.
That's it. Leave the tab open and VClock counts down in the background. When the time arrives your alarm rings, the display flashes, and you can stop it or snooze for another nine minutes.
A browser alarm clock that just works — nothing to install, nothing to sign up for.
Every feature is free with no daily limit, no trial period and no premium tier. Set one alarm a week or twenty a day — the experience is identical.
Six alarm tones generated in real time by your browser, so nothing has to download and the sound never lags. Volume follows your system volume.
Windows, Mac, Linux, Chromebook, Android and iPhone. If it runs a modern browser, it runs VClock — no app store, no permissions.
Alarm clock, countdown timer, stopwatch, world clock, date countdown and Pomodoro timer all live on the same site and share the same clean interface.
Stack as many alarms as you need and snooze any of them, exactly like a physical bedside clock — useful for shift work, medication reminders and nap schedules.
Alarms are saved in your own browser storage. There is no account, no cloud sync and nothing about your schedule ever leaves your device.
An online alarm clock is a browser-based tool that rings at a time you set, without needing a physical clock or a phone app. You open a web page, type the time you want to wake up or be reminded, and the page keeps track of the countdown for you. When the moment arrives, the browser plays an alarm sound and shows a visual alert.
The appeal is simple: it takes seconds to set, it works on any device with a browser, and there is nothing to install. If you are already sitting at a computer — working, studying, cooking or napping at your desk — reaching for the browser tab you already have open is faster than picking up your phone and navigating to the clock app.
The right alarm sound depends on how deeply you sleep and what is around you. Here is what each VClock sound is designed for:
| Sound | Character | Best for |
|---|---|---|
| Beep | Classic double beep, medium pitch | General reminders, desk alarms |
| Digital | Sharp triple beep, high pitch | Short timers, kitchen use, noisy rooms |
| Alarm Bell | Fast alternating tones like a mechanical bell | Waking up, heavy sleepers |
| Chime | Rising bell tones that decay slowly | Meditation, gentle nudges, offices |
| Siren | Continuous rising and falling sweep | Hard deadlines you absolutely cannot miss |
| Soft Wake | Warm ascending notes, low volume | Naps, babies sleeping nearby, early mornings |
If you are a deep sleeper, research on waking consistently points in one direction: a sound with a clear melodic structure tends to reduce grogginess more than a harsh buzz. Try Chime or Soft Wake for a week before defaulting to Siren.
A browser alarm is reliable, but a browser is still a browser. Four habits make it dependable:
The alarm clock is the front door, but VClock is a complete timekeeping suite:
| Physical alarm clock | VClock online alarm | |
|---|---|---|
| Cost | $15–$60 | Free |
| Setup time | Buttons, menus, AM/PM confusion | Type the time, press Set |
| Multiple alarms | Usually one or two | Unlimited |
| Labels | No | Yes, per alarm |
| Time accuracy | Drifts, needs resetting | Synced to your device clock |
| Extra tools | Rarely | Timer, stopwatch, world clock, Pomodoro |
| Works during a power cut | Yes (battery models) | No |
The one thing a bedside clock still wins on is independence from power and browsers. For everything else — speed, flexibility and cost — a browser alarm is hard to beat.
An alarm is only half of the equation. If you struggle to get up, these evidence-backed habits help more than a louder ringtone: keep the same wake time every day, including weekends, so your body clock stops fighting you; put the device across the room so stopping the alarm means standing up; get daylight within 30 minutes of waking, which is the strongest signal your circadian rhythm responds to; and avoid stacking five snoozes, because fragmented sleep after the first alarm leaves you groggier than simply getting up.

Common questions about using the VClock online alarm clock.
Yes. VClock is completely free to use. There is no sign-up, no download, no subscription and no limit on how many alarms or timers you set.
Yes. As long as the VClock tab stays open in your browser, the alarm keeps counting and will sound at the set time even if you are working in another tab or another window. Do not close the tab or put the computer fully to sleep.
No. VClock runs entirely inside your web browser. It works on Chrome, Edge, Firefox and Safari on Windows, Mac, Linux, Android and iPhone with nothing to install.
Browsers block audio until you interact with the page. Click anywhere on VClock once (setting the alarm counts) and the sound will be unlocked. Also check that your device volume is up and the browser tab is not muted.
Yes. Pick from Beep, Digital, Alarm Bell, Chime, Siren or Soft Wake in the sound menu. Selecting a sound plays a short preview so you can hear it before you commit.
No. If the computer goes into full sleep or hibernation, the browser is paused and the alarm cannot ring. Change your power settings to keep the screen on, or use the built-in screen wake feature by keeping the tab active.
Yes. Add as many alarms as you like — each one appears in the list below the clock with its own label and can be removed individually.
When an alarm rings, pressing Snooze silences it and automatically creates a new alarm 9 minutes later (you can change the snooze length). It works exactly like the snooze button on a physical alarm clock.
Yes. Your alarms and preferences are stored locally in your own browser, so they are still there after a refresh. Nothing is uploaded to a server and nothing is linked to your identity.
VClock reads the time directly from your device clock, so it is exactly as accurate as your computer or phone — which normally syncs automatically with an internet time server.
Switch to the VClock online timer for cooking, workouts and study sessions.
