## What it is
Knot is a full-featured iOS app for capturing and analyzing HTTP/HTTPS network traffic using MITM (man-in-the-middle) techniques, built entirely in Swift with SwiftNIO for the core networking code. It supports traffic parsing, multi-format export, LAN device capture, CA certificate installation/export, and filter rule configuration.

## Use cases
- capture https traffic on iphone
- debug api requests from ios apps
- inspect network traffic from lan devices
- install mitm ca certificate on ios
- export captured http requests
- analyze app network behavior on device

## When to choose
- you need on-device HTTPS packet capture on iOS without a desktop proxy
- you want to inspect traffic from other devices on the same LAN
- you prefer an open-source, self-buildable capture tool with full source code

## When to avoid
- you need a cross-platform or desktop packet capture solution
- you want a ready-to-install App Store app without building with your own Apple account
- you need protocol support beyond HTTP/HTTPS out of the box
