TunnelSight is an on-device network microscope for iOS that makes zero-trust testing and traffic analysis simple for developers, network engineers, and security researchers. It captures HTTP/S traffic locally with a lightweight, secure architecture, then lets you replay requests as cURL and export/alter request/response pairs as structured JSON. Built for professional iOS development, it keeps analysis fast, private, and completely on-device. With a scripting engine api security testing is easy.
