## What it is
ProxyBridge is a free, open-source universal proxy client (Proxifier alternative) that transparently redirects TCP and UDP traffic from any application through SOCKS5 or HTTP proxies on Windows, macOS, and Linux. It works at the system level with per-application routing, blocking, and allow rules, requiring no configuration of the proxied applications.

## Use cases
- force a proxy-unaware desktop app through a SOCKS5 proxy
- redirect TCP and UDP traffic of specific processes to an HTTP proxy
- route thick client application traffic through a proxy for testing
- block or allow network access per application
- send all system traffic through a proxy without per-app configuration
- intercept non-HTTP application traffic by pairing with a MITM proxy
- test IoT or proprietary protocol clients through a proxy

## When to choose
- you need a free, open-source Proxifier alternative on Windows, macOS, or Linux
- you need to proxy both TCP and UDP traffic, not just TCP
- you want per-application control over routing, blocking, or allowing traffic
- the target application is proxy-unaware and cannot be configured
- you want to funnel thick-client traffic into a MITM proxy for security testing

## When to avoid
- you only need HTTP browser traffic proxied - a simple browser proxy setting suffices
- you need full MITM inspection with TLS decryption and packet editing - pair it with a dedicated interception tool
- you need a VPN-style full-system tunnel with encryption rather than proxy redirection
- you require a graphical policy manager beyond per-application rules
