ProxyDeck is a free network lab and local proxy for iPhone. Check DNS, HTTPS, TCP, and local SOCKS5 paths directly on your device, without a Mac or account. Looking for the iPhone app that works with FastNet Connect? This is it. ProxyDeck's optional Mac Bridge connects to the separately purchased FastNet Connect app on an Apple Silicon Mac over USB or nearby peer-to-peer Wi-Fi. Mac Bridge requires both apps and works only while ProxyDeck stays in the foreground. It stops when you leave the app. 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.
