Spider Proxy - HTTP(S) Catcher

Spider Proxy is a powerful mobile HTTP/HTTPS network debugging and packet capture tool for iOS. Inspect, analyze, and modify HTTP/HTTPS requests and responses directly on your iPhone or iPad without connecting to a computer. It supports request export and customizable debugging, including URL redirection and custom headers—making it an essential tool for developers and testers.
