ByteSniffer brings professional-grade packet capture and network analysis to iOS. It routes device traffic through a local VPN extension, reads IP packets before they leave or after they arrive, and gives you real-time visibility into what your device is actually doing on the network. Built for developers and security-minded users, it keeps analysis on-device and focused on raw packet insight.

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.
