HTTP Catcher vs Spider Proxy

HTTP Catcher is a web debugging proxy. It can be used to intercept, inspect, modify and replay web traffic. You don't need to connect to a computer, HTTP Catcher records HTTP traffic under Wi-Fi and cellular networks in the background. HTTP Catcher makes it easy to test your apps and websites, and you can view requests and responses directly. HOW IT WORKS HTTP Catcher creates a local VPN on your device. When you start to capture web traffic, HTTP Catcher will launch a local http proxy in VPN process. All of your web traffic will be forwarded to the local http proxy via VPN. FEATURES * Decrypt HTTPS traffic * View WebSocket * Block URL * Replay request * Modify requests and responses on the fly * Domain name filter * HTML, JavaScript, CSS reformat and re-indent * HEX viewer * DNS mapping
