How It Works

01

Create a Room

Pick a name and optional password. Rooms are instant - no signup needed.

02

Share P2P

Send files, chat, code, or content. Everything goes directly to connected peers. No uploads.

03

Direct & Fast

Browser-to-browser via WebRTC. The relay only helps find peers - your data stays between you.

Features

Every peer connects to every other peer directly. No central server bottleneck.

Password Rooms

Room-level passwords enforced server-side. Only the right people get in.

Share text, code, notes, or files of any size. Drag, drop, done.

Retention Control

Per-item: session, 5 min, 1 hour, 1 day, or forever. You decide.
