Keynou Clipboard's server is a relay, not a storage system. It passes WebSocket messages between connected clients but never writes text to disk, a database, or logs. Your text exists only in the RAM of connected browsers and the server's transient memory during relay.
The server only forwards Socket.io events between connected clients. It has no database, no file system writes, and no text logging.
There is no database. The server uses an in-memory Map to track connected users and rooms. Restart the server and everything is gone.
Each session is isolated - only participants with the exact link can receive messages. The server doesn't broadcast across sessions.
The server code is simple and auditable. You can read the entire server.js file and verify that no text is ever stored or logged.
Client A types text and sends a WebSocket event to the server.
The server receives the event and relays it to all other clients in the same session room.
The server does not store, log, or cache the text - it only forwards the event.
Other clients receive the event and update their editor in real-time.
Share text knowing the server only relays it - no storage, no caching, no logging. Your text passes through, never stays.
In environments with strict data retention rules, the relay model means there's nothing to retain, audit, or delete.
Share code snippets peer-to-peer with confidence. The server relays the text but never stores it - perfect for proprietary code.
Self-host Keynou Clipboard on your own server for complete control over the relay. The server stores nothing, so there's nothing to compromise.
Keynou Clipboard uses a relay model - the server passes messages between clients but stores nothing. True browser-to-browser WebRTC is on the roadmap for even more direct peer connections.
No. The server only relays Socket.io events between connected clients. Text exists only in the RAM of connected browsers and the server's transient memory during relay. No disk, no database, no logs.
Cloud clipboard tools store your text on servers in a database. Keynou Clipboard's server only relays messages - your text is never persisted anywhere. This is fundamentally more private.
Yes. Keynou Clipboard is a standard Node.js application. You can self-host the entire server on your own infrastructure for complete control over the relay.
Keynou Clipboard is ephemeral by design. Your text exists only in server memory (RAM) during the active session. No database, no files, no logs. When the session ends, all content is permanently deleted with zero recovery possible.
Keynou Clipboard requires zero authentication. No accounts, no email verification, no passwords. Open the editor and start typing immediately. Share a link and anyone can join - no signup barrier for your collaborators either.
Keynou Clipboard's real-time collaboration lets multiple people edit the same text simultaneously. Every keystroke syncs instantly via WebSocket - no refresh, no delays, no polling. See where each person is typing with colored cursor labels and per-user text highlighting.
Keynou Clipboard runs in any modern browser on any platform - Windows, macOS, Linux, iOS, and Android. It's also a Progressive Web App (PWA), meaning you can install it to your home screen or desktop for a native app experience. No app store required.
Open the editor and try it for yourself. No login, no signup, no storage.
