Download Peerino
Peerino provides a direct file transfer mechanism between two computers using WebRTC technology. The application generates shareable links that allow recipients to download files through a standard browser without installing any software. For inbound transfers, users create an inbox link that permits external parties to upload files directly to the Peerino user's machine. The system employs DTLS encryption for all internet-based transfers and offers a plain HTTP fallback for local network scenarios. No account registration, cloud storage, or intermediary file hosting is involved in the process. The application is available for Windows and distributed as open source software.
This desktop tool enables peer-to-peer file exchanges without relying on centralized servers for data storage. Users can send files by generating a link and sharing it through any communication channel. Recipients download the file from their browser while the sender remains online. The application also supports receiving files from individuals who do not have Peerino installed. All internet transfers are encrypted end-to-end with DTLS, and a TURN relay handles restrictive network conditions. The program includes SHA-256 integrity verification for incoming browser transfers. Link expiration policies apply to relay and inbox links, with a 24-hour validity period.
Peerino is a Windows application for sharing files directly between computers. It uses WebRTC to establish peer-to-peer connections and falls back to a TURN relay when network address translation prevents direct links. The application does not require user accounts, does not store files on remote servers, and does not collect personal information. Files can be shared via generated links that recipients open in a browser. Inbox links allow other people to send files to the Peerino user. The software is open source under AGPL-3.0 and remains free to use. macOS and Linux versions are planned for future releases.
