About Charles Proxy
Charles is a web debugging proxy that sits between your apps and the internet so you can see every HTTP and HTTPS request and response. It has been a standard tool for web and mobile developers for well over a decade, offering SSL proxying, breakpoints for editing requests in flight, rewrite and map rules, throttling to simulate slow networks, and repeat requests. Version 5 brought a refreshed interface, inline search and better performance with large payloads. It runs on Windows, macOS and Linux (including Arm builds) and is made by a small independent developer, XK72. You can try it free for 30 days, then buy a per-user license, with volume and site licenses for organisations; each license covers one major version. The interface still feels dated next to newer tools, and there is no scripting API on the level of mitmproxy.
Best for: Developers and QA testers who want a proven GUI proxy at a low one-time price.
