ShadowsocksX

It provides a SOCKS5 proxy that tunnels traffic through an encrypted channel, allowing users to bypass network restrictions and firewalls. The proxy employs asynchronous I/O and event‑driven programming to achieve high throughput with low latency, and it supports a range of encryption algorithms that can be customized.

The tool is designed for use on a wide variety of devices, from desktop operating systems such as Windows, Linux, and macOS to mobile platforms including Android and iOS, as well as embedded environments like OpenWRT. Its lightweight implementation aims to keep CPU and bandwidth consumption minimal, making it suitable for mobile and wireless networks.

The project is open source and offered at no cost, with a stable release status. It is intended for anyone who needs a flexible, cross‑platform solution to secure their internet traffic and circumvent censorship or filtering mechanisms.
