A browser alarm clock should work without an extension, without a download, and without leaving the laptop on overnight. This page is exactly that: open it in any modern browser, set the hour and minute, choose Telegram or push delivery, and the alarm is registered on the server. Because the alarm fires server-side, you do not need to keep the browser open. You do not need to keep the laptop awake. You can close the tab right after pressing Set and the notification still goes out at the right time. The page is just the configuration surface; the actual delivery infrastructure is the same one we use for full reminders, contacts, and recurrence. What you get for free, without an account: Telegram delivery (one-time link with our bot), browser push delivery (one-click subscribe), and the in-tab chime. With an account you also get email delivery and the ability to share the alarm with linked contacts. There is no premium tier required for the basic alarm; it has been free since the project launched.

FAQ

Does this work in Safari?
Yes. Telegram delivery works in any browser. Browser push works in Safari 16.4+ on macOS and as a Home Screen PWA on iOS 16.4+.
Does it work offline?
Setting the alarm requires a network connection so the server can schedule it. Once scheduled, delivery is independent of the browser being online — push and Telegram come from our backend.
How is this different from the OS alarm clock?
Cross-device: set on the laptop, receive on the phone via Telegram or push. Multi-channel: redundant delivery means you don't oversleep when one channel fails. No install, no permissions besides notifications.
Is the source code open?
The remindmenow project's source is private. The features listed here describe runtime behaviour, not internals. If you need an open-source alarm tool, the project is not the right fit.
