10/12/2026 14:01File TransferP2PIntranetDesktop App

One-click connect two computers for encrypted P2P file transfer, intranet penetration, and remote SSH.

Problem: Existing file transfer tools either rely on cloud storage (like the discontinued 奶牛快传) or require complex setup (like native Tailscale CLI). Users need a simple, clean, out-of-the-box P2P solution.
Solution: A cross-platform desktop app based on the open-source tailcat project, providing a GUI. Open the app to directly connect two computers, supporting encrypted P2P file transfer, intranet penetration, SSH, chat, and audio/video without public IP or complex config.
Users: Remote workers, developers, families, small teams needing frequent file transfers.
MVP: GUI client based on tailcat; one-click connect two devices; encrypted P2P file transfer; basic SSH; cross-platform (Win/Mac/Linux).
Revenue: Free basic features; premium offers multi-device management, larger transfer limits, priority support, one-time purchase or subscription.
Why now: Tailscale open-sourced tailcat lowering technical barriers, persistent demand for simple secure transfer tools, indie devs can quickly wrap it.
