Sharednight is a small, free website built around one idea: a quiet room you can leave open while you fall asleep.
You pick a name that is unique inside the room and choose a gender for your little illustrated sleeper. A bed is then assigned automatically — you cannot choose a room or a bed. Each room holds twenty sleepers; when it fills, a new named room opens automatically.
After that you choose one sleep sound, optionally set a sleep timer or dim the screen, and leave the tab open. There is no app to install, no account, no chat, no video and no advertising.
Every room is given a name generated automatically from a mood word and a place word — Moonlit Attic, Quiet Bay, Velvet Observatory and so on. The room name catalogue lists the full current set on a single page. Names are generated by the page itself; there is no hand-written list to fall out of date.
The player offers 22 sounds. Nature and household scenes use real recordings that are trimmed and loop-smoothed in your browser; noise colours, binaural tones, lullabies and music are generated live with the Web Audio API. Any two sounds can be layered. Sources and licences are listed on the audio credits page.
Nothing you type is stored or synced. The name, sleeper and bed exist only in the current browser tab and disappear on reload. See the privacy policy.
It is an ambient player, not medical advice and not a treatment for any sleep condition. Please read the disclaimer.
