ProxyBridge is a lightweight, open-source universal proxy client (Proxifier alternative) that provides transparent proxy routing for applications on Windows and macOS. It redirects TCP and UDP traffic from specific processes through SOCKS5 or HTTP proxies, with the ability to route, block, or allow traffic on a per-application basis. ProxyBridge fully supports both TCP and UDP proxy routing and works at the system level, making it compatible with proxy-unaware applications without requiring any configuration changes.
🚀 Need advanced traffic analysis? Check out InterceptSuite - our comprehensive MITM proxy for analyzing TLS, TCP, UDP, DTLS traffic. Perfect for security testing, network debugging, and system administration!
- Cross-platform - Available for Windows and macOS
- Dual interface - Feature-rich GUI and powerful CLI for all use cases
- Process-based traffic control - Route, block, or allow traffic for specific applications
- Universal compatibility - Works with proxy-unaware applications
- Multiple proxy protocols - Supports SOCKS5 and HTTP proxies
- System-level interception - Reliable packet capture at kernel/network extension level
- No configuration needed - Applications work without any modifications
- Protocol agnostic - Compatible with TCP and UDP protocols (HTTP/HTTPS, HTTP/3, databases, RDP, SSH, games, DTLS, DNS, etc.)
- Traffic blocking - Block specific applications from accessing the internet or any network (LAN, localhost, etc.)
- Flexible rules - Direct connection, proxy routing, or complete blocking per process
- Advanced rule configuration - Target specific processes, IPs, ports, protocols (TCP/UDP), and hostnames with wildcard support
- Process exclusion - Prevent proxy loops by excluding proxy applications
- Import/Export rules - Share rule configurations across systems with JSON-based import/export

Windows Implementation: This project is built on top of WinDivert by basil00. WinDivert is a powerful Windows packet capture and manipulation library that makes kernel-level packet interception possible. Special thanks to the WinDivert project for providing such a robust foundation.
Based on the StreamDump example from WinDivert: https://reqrypt.org/samples/streamdump.html
The Windows GUI is built using Avalonia UI - a cross-platform XAML-based UI framework for .NET, enabling a modern and responsive user interface.
macOS Implementation: Built using Apple's Network Extension framework for transparent proxy capabilities on macOS.
