HTTP Inspection Tools of Note

We here at Port80 look at lots of tools to monitor HTTP requests and responses.

Some of the tools are implemented as proxies, allow rewriting of headers and all sort of fun stuff, while others plug-in to the browser and monitor the requests passively.  While folks may know of LiveHeaders for Mozilla ( or HttpWatch for IE (, here are a few more that we have found varying in price and capabilities.

Stuck in the middle with you — a few proxies:

We quite like this proxy, which is being updated all the time.

A Java-based HTTP proxy to see full headers — and change ‘em on the fly.

Another Java-based HTTP inspection proxy.

Toolbars!  Toolbars!  Get your HTTP toolbars here!:

IE Inspector – HTTP Analyzer
Similar to the popular HttpWatch but cheaper — the DOM inspector though is much more interesting…

Interesting integration with the specification to show you header information and decent filtering.

This is a packet sniffer that can see all the HTTP stuff going on – on your box.  When you need a powertool, Bob Villa-style.

Yet another IE plug-in — is there a pattern of free tools emerging here?

Yet another IE plug-in — but this one is FOSS for the budget-minded (free and open, baby).

We even have our own internal tool (httpScope) that we use internally.  It may one day be released at a Port80 near you…

  • Is there a free tool similar to httpwatch to work on mozilla. I dont mind adding a few lines of code but something that could be the closest would be great!!

  • You didn’t mention the HTTP Debugger, which costs only $50 🙂
