Scales well on modern SMP hardware, handling 10s of thousands of requests per second. Easily add keep-alive, filter or anonymize content requests, or add load balancing by adding a proxy layer. APIs to write your own plug-ins to do anything from modifying HTTP headers to handling ESI requests to writing your own cache algorithm.

Potatso
Potatso is a powerful, user-friendly networking tool that lets you create a fully customized network environment without complex setup. It supports Shadowsocks, ShadowsocksR, HTTP, and SOCKS5 proxies, either self-hosted or provider-supplied, and runs reliably in the background over both Wi-Fi and cellular data. You can define custom DNS servers and build granular routing rules by domain, IP range, or keyword to send selective traffic through different proxies or direct connections, while its smart‐routing feature optimizes performance for Chinese users by bypassing the proxy for domestic sites and reducing data costs. Potatso logs and displays real-time connection statistics, including speed, latency, and data usage, so you can monitor and troubleshoot network behavior, and it integrates with iCloud to sync your proxy profiles and rule sets across devices.
