What is this?
ProxyBridge is a cross-platform proxy client that transparently redirects TCP and UDP traffic from specific Windows/macOS/Linux applications through SOCKS5 or HTTP proxies, acting as an open-source alternative to Proxifier.

Inspecting and editing traffic is the job of its sibling project, InterceptSuite.
