About Offline P2P Chat
Doffl's Offline P2P Chat provides a decentralized messaging environment that connects your device straight to peers without passing traffic through central storage servers. By leveraging browser-native WebRTC technology, users can initiate instant conversations and transfer files securely across local networks or direct web connections.
This utility is built for privacy-focused individuals, teams operating on closed networks, and environments with intermittent internet access. Because the tool runs entirely inside your browser, no software installation, user registration, or account configuration is required to establish a peer-to-peer connection.

Frequently asked questions
Can I use this P2P chat without an active internet connection?
Yes. Once the web application is cached in your browser, devices on the same local network or Wi-Fi hotspot can connect directly without external internet access.
Are messages or files saved on Doffl servers?
No. Data travels directly from one device to the other via WebRTC data channels. No text, media, or connection logs are stored or monitored on any server.
Is there a limit on file sharing sizes?
Because data transfers directly between devices without cloud intermediaries, file size limits depend primarily on the available RAM and browser limits of the connected devices.
Do I need to install any browser extensions or apps?
No installation is required. The tool operates natively within any WebRTC-compliant web browser, including Chrome, Firefox, Safari, and Edge.
Is Offline P2P Chat free to use?
