Is there an OS X equivalent to the web debugging proxy Fiddler?

I do web development on Windows for my day job, and I rely a lot on Fiddler, which is web debugging proxy. What is an equivalent tool for OS X?

Solution 1:

I use CharlesProxy, and while it isn't as scriptable as Fiddler, it does the job. And with single license key, you can run it on all OSes (it's written in Java).

My needs were little different when I needed it ... I used it to debug webdav connections or to debug http communication between servers.

Solution 2:

Stuff that's Free:

• Burp Suite
• WiireShark
• ParosProxy
• NetTool
• LiveHTTPHeaders
• Safari WebInspector Network Tab
• FireBug

Stuff that Costs:

• $1.99 - HTTPClient
• $15.00 - HTTP Scoop
• $50.00 - CharlesProxy

Solution 3:

These are both free and haven't been mentioned so far. I found that both of these are far superior to the X11 Wireshark.

• Cocoa Packet Analyzer
• Packet Peeper

Solution 4:

http://mitmproxy.org/ is text-based tool, but does a great job. For any http-speaking app you want to analyse, and even modify and replay requests.
