Free Online Alarm Clock

An online alarm clock lets you set a wake-up time straight from your browser — no app install, no account, and no cost. Lull's alarm runs entirely in your web tab, so you can open it on a laptop, desktop, or tablet and wake on time wherever you are. Pair it with Lull's sleep sounds and sleep timer for a complete overnight companion.

Why use an online alarm clock?

A browser-based alarm is handy when your phone is across the room, charging, or simply something you'd rather not keep next to the bed. Because everything runs locally in the tab, there is nothing to download and no service to sign up for. It is especially useful for:

Harsh alarms can jolt you out of deep sleep and leave you groggy. Lull lets you choose a gentler wake-up sound: steady rain, rolling ocean waves, soft wind, a fan hum, crackling campfire, or white, pink, and brown noise. Prefer tradition?
