This is a completely LAN-based file transfer terminal. Speed Share does not use any servers, does not consume your mobile data, and does not collect any user data. It enables peer-to-peer transmission.

You can quickly share text messages, images, or other files and folders.

It is suitable for LAN file transfer, solving the problem of files being routed through servers in applications like QQ and WeChat.


This repository is still under development and maintenance. However, due to my regular work, I do not have much free time, and I haven’t had the opportunity to update related screenshots, etc. I apologize for the inconvenience!

Since I started my full-time job, I no longer have a lot of energy to invest in open-source projects.
