Fiddler Alternatives

Fiddler is described as 'Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data' and is a very popular http(s) debugger in the development category. There are more than 25 alternatives to Fiddler for a variety of platforms, including Windows, Mac, Linux, Online / Web-based and iPhone. The best alternative is Wireshark, which is both free and Open Source. Other great apps like Fiddler are Charles, mitmproxy, Burp Suite and OWASP Zed Attack Proxy (ZAP).

Fiddler alternatives are mainly HTTP(S) Debuggers but may also be Web Debuggers or HTTP Clients. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Fiddler.

    OWASP Zed Attack Proxy (ZAP) vs Fiddler opinions
    This alternative is disputed. OWASP Zed Attack Proxy (ZAP) is still a legitimate alternative to Fiddler, but it might have issues that some users think are important.

    ZAP is a proxy for attacks, not a proxy for development

    Fiddler is for super-user, and unfriendly for newbie. Proxyman is designed by strictly following the macOS human guideline from Apple, so it feels like the home.
