Socks5 Smart Router is a free Chrome add-on designed to enhance browsing by enabling intelligent domain-based SOCKS5 routing. This tool allows users to configure a SOCKS5 host and port, and set specific routing rules using domain names, wildcards, or regular expressions. By utilizing PAC mode, the add-on ensures safe and efficient routing of internet traffic.

The functionality of Socks5 Smart Router is straightforward: traffic matching the defined rules is routed through the SOCKS5 proxy, while other traffic is sent directly. In case the proxy becomes unavailable, the add-on automatically falls back to DIRECT routing, ensuring uninterrupted access. Importantly, the tool does not collect user data or intercept background traffic, prioritizing user privacy and control.
