iPhone

Diagnose DNS, HTTPS, TCP, and SOCKS5 paths directly on your iPhone. No account, analytics, or data collection. ProxyDeck is a focused network lab and local proxy for iPhone. It helps developers and power users find where a connection path breaks, directly on the device. Run four practical checks against any host: • DNS resolution — inspect the addresses returned on the current network • HTTPS request — verify an end-to-end secure request and response • TCP path — measure connection setup to port 443 • Local SOCKS5 — prove the built-in 127.0.0.1 proxy with a real CONNECT request Every proxy flow appears in a live connection inspector with its host, port, protocol, state, and traffic totals. Optional Mac Bridge If you use FastNet Connect for macOS, ProxyDeck can expose its proxy over USB or a nearby peer-to-peer connection. This companion mode is optional and starts only when you tap Start Mac Bridge. The standalone Network Lab requires no Mac or other app. Private by design: • No account • No analytics or tracking • No data collection • No servers operated by us • Diagnostic checks contact only the host you enter Mac Bridge is a foreground-only tool and stops when ProxyDeck leaves the foreground.
