Looking for an OnlineClock.net Alternative? Here's a Free One

For almost twenty years, OnlineClock.net was the web's default answer to "I need an alarm and my phone isn't an option." You opened the page, set a time, left the tab open, and it rang. People used it as a bedside clock, a nap timer, a backup for phone alarms that had failed them once too often. It did one thing, reliably, for free, with no account — which is exactly why so many bookmarks pointed at it.

In early 2026 the original site went offline. The domain is still live today, but what's there now is a different product from different owners, and longtime users on Reddit have been blunt about missing the original: too bright for a dark bedroom, and the simple set-an-alarm flow they came for isn't what it was.

What made the original worth replacing properly

Reading what its users actually mourned, the list is short and specific. It loaded instantly. It never asked you to sign up. It had a dark mode you could leave on all night without lighting up the room. And the alarm was foolproof: set it, test it, stop it. Any real alternative has to clear that bar before adding anything else.

A free replacement in your browser

Our online alarm clock is built to be exactly that kind of replacement:

• Set it in two taps.Pick a time, arm it, done. The alarm state is saved in your browser, so a page reload doesn't lose your settings — and there is no account, ever.
• Night dim built in. The moon button drops the whole display to a fraction of its brightness — dim enough for a bedside table, still readable when you half-open one eye.
• Snooze and stop that just work. When it rings, you get two big buttons: snooze for five minutes, or stop — which quietly re-arms the alarm for the same time tomorrow.
• A test button.Play the alarm sound once before you trust it with your nap. It stops when the burst ends — no way to get stuck in a test you can't exit.

One honest limitation

Like the original, and like every alarm site: the tab has to stay open. Browsers don't let a closed tab make noise, and any site that claims otherwise is overpromising. Leave the tab open, turn on Keep Screen On if the device tends to doze off, and check your volume with the test button. For anything mission-critical — a flight, not a nap — set a hardware backup too. That's not a weakness of one site; it's just what browser alarms are.

If you used it as a plain bedside clock

Plenty of people kept OnlineClock.net open all night without ever setting an alarm — it was just a big, dark, readable clock. For that use, the plain LED digital clock with a dim color like LED Red, plus Keep Screen On, does the same job. The alarm page works for it too: leave the alarm off and use the night dim button.

The original site earned two decades of bookmarks by refusing to complicate a simple job. That's the standard we're holding the alarm clock to: free, no signup, dark at night, and an alarm that rings when you told it to.
