About InterceptSuite/ProxyBridge
ProxyBridge is a lightweight, open-source universal proxy client that acts as a Proxifier alternative. It provides transparent proxy routing for applications on Windows, macOS, and Linux, redirecting TCP and UDP traffic from specific processes through SOCKS5 or HTTP proxies. The tool works at the system level via kernel/network extension interception, making it compatible with proxy-unaware applications without requiring any configuration changes. It supports per-application traffic control—routing, blocking, or allowing traffic—and is built by the same team behind InterceptSuite.
Key Features
Cross-platform support (Windows, macOS, Linux)
Dual interface – feature-rich GUI and powerful CLI
Process-based traffic control – route, block, or allow traffic for specific applications
Universal compatibility – works with proxy-unaware applications
Supports SOCKS5 and HTTP proxy protocols
System-level interception – packet capture at kernel/network extension level
No configuration changes required for target applications
Protocol agnostic – handles TCP and UDP (HTTP/HTTPS, HTTP/3, databases, RDP, SSH, games, DTLS, DNS, etc.)
Traffic blocking – ability to block specific applications from network access
Pros & Cons
Pros
- Free and open source
- Works across all major desktop operating systems
- Does not require modification of target applications
- Supports both TCP and UDP traffic routing
- Offers both graphical and command-line interfaces
- Per-application granular control for routing, blocking, or allowing traffic
- Active development with regular releases and community support
Cons
- System-level installation may require admin/root privileges
- Linux version requires kernel with NFQUEUE support
- Windows winget package is community-maintained and may lag behind official releases
- No built-in proxy server or VPN functionality – focuses only on transparent proxying of existing traffic
