Why Floop

Built for people who just want to chat.

No feeds. No reactions. No filler. Just a fast, clean interface that connects you to the people you want to talk to.

Instant by design

Messages arrive in milliseconds, thanks to Floop's usage of WebSockets.

Your history, your machine

Your chat history is stored in an SQLite database on your machine. Keep your data in your hands.

Presence that works

Online, Away, Busy, Offline - statuses that update in real-time, not after a couple minutes.

Open protocol

The Floop protocol is documented and open. Build your own client or server - no permission needed.

Typing indicators

See when someone is typing. Subtle, unobtrusive and clean.

Organised contacts

Group your contacts in categories. No suggested contacts, no nonsense.
