Summary

ShrimpSend (虾传) is an open-source cross-platform file transfer system that enables direct connections under restricted networks like NAT and hotel Wi-Fi, supports resumable transfers, and transfers files directly between devices without a server relay.

Reliably transfer files between phone, computer, and browser—works even under restricted networks like NAT, hotel Wi-Fi, campus networks; large files support resume. https://github.com/shrimpsend/shrimpsend… ShrimpSend (虾传) is a cross-platform file transfer system that doesn't follow the "upload → share link" approach; instead, it establishes a direct channel between devices. On the same local network, it uses HTTP or WebRTC for direct transfer; if crossing networks fails, it falls back to a server relay or S3 backend. Large file transfers can resume after interruption, and recipients can receive files via browser even without installing the app. The backend is Spring Boot + MySQL + Centrifugo for real-time push, and clients cover iOS, Android, desktop (three platforms), and Web. Supports self-hosting and has an official hosted version.
