## What is ProxyDeck?

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.
