App Proxy Router is a Linux alternative to Proxifier. It runs a local SOCKS5 + HTTP proxy listener and routes every connection by your rules through upstream proxy chains, directly, or blocks it.

Features (all operate on real sockets):

• Proxy profiles: SOCKS5 and HTTP CONNECT upstream proxies with username/password auth
• Multi-hop proxy chains (hop 1 -> hop 2 -> ... -> target)
• Local listener on one port speaking SOCKS5, SOCKS4/4a and HTTP (CONNECT + plain GET), optional Basic/username auth
• Rules by host glob, domain, CIDR and port ranges -> Direct / Proxy / Block (first match wins)
• DNS through proxy option (hostnames are resolved by the upstream proxy)
• Live connection log with protocol, target, matched rule, route, bytes sent/received, duration; CSV export
• Proxy checker: opens a real tunnel through a profile or the whole chain and sends an HTTP HEAD, with latency
• Launch app via proxy: starts a command with http_proxy / https_proxy / ALL_PROXY pointing at the local listener, or copies the export lines for your terminal

Honest limitations: there is no kernel-level transparent redirection. Applications are routed only when they are configured to use the local proxy or honour proxy environment variables; apps that ignore them are not forced. UDP is not proxied.
