UU VPN Proxy: Proxy Switcher

Quickly add, manage, and switch proxy servers, with authentication, speed testing, and domain-based routing.

UU VPN Proxy is a focused proxy manager for Chromium-based browsers. Add and switch HTTP, HTTPS, and SOCKS5 proxy servers from a clean popup, then choose global routing or precise domain-based rules. Key features: • Manage multiple proxy profiles • Parse six common proxy formats and fill the form automatically • Switch the active proxy and test latency from the popup • Route all traffic globally or use custom and built-in domain rules • Create proxy and direct-connect rules with suffix and wildcard matching • Import and export local JSON configuration backups • Use light, dark, or system appearance • Follow the browser language or choose from 18 interface languages • Optionally synchronize encrypted configuration across devices Privacy and control: • Core proxy features work locally without an account • Optional cloud synchronization encrypts configuration in the browser before upload • No advertising or analytics are included • Exported JSON files contain proxy credentials in plain text and should be stored securely Important: Chromium-based browsers do not support username/password authentication for SOCKS5 proxies. Use an unauthenticated SOCKS5 endpoint or HTTP/HTTPS proxy authentication instead.
