HTTP Scoop is an HTTP protocol analyser, a.k.a. "HTTP sniffer". It passively captures HTTP conversations and presents their details in real-time.

  • Use to debug Web scripts/applications
  • View responses as hex, text (syntax-highlighted for XML/HTML) or as images
  • Any browser or server technology - no proxy needed
  • View headers, parameters and POST data
  • Save responses to disk
  • Fully decodes HTTP (handles GZIP compression, request pipelining etc.)

What's New

Version 1.4:
  • HTTP performance analysis
  • Easier navigation
  • Faster, less memory hungry, more stable
  • Slicker updates


Mac OS X 10.4 or later

Not working in Mountain Lion. No response from the developer. Don't buy it.

Awesome. Incredibly useful for debugging image upload/massage/download issues, ajax transactions, header problems, etc. Particularly nice to be able to see an overview and then easily drill down to relevant data.

HTTP Scoope is exactly what i searched for !
it works perfect with the local interface, airport and ethernet with a router but the app really needs support for the (ppp0) interface. i'm afraid without point-to-point protocol - point-to-point over ethernet support it is useless for me.

I have been using this app for over a year now and I have to say it has been indispensable whilst developing various web apps. I work a lot with SOAP web services and HTTP Scoop helps me to get to the root of any problems quickly and easily.

No bells and whistles, it just does what it should and helps any serious web dev get on with the important bits.

The developer is very helpful and responds quickly to any questions. I had occasion to use IP over FireWire for a particular project. When I discovered that HTTP Scoop didn't work on FireWire connections I contacted the developer and within a couple of days he had sent me an updated version which was FireWire compatible.

1. HTTP Client isn't free (it's $1.99 in the App Store)

2. HTTP Client does a different job (just a subset of what HTTP Scoop does)

HTTP Client can't tell you what URLs an app is loading, it just loads the single URL you give it and then shows you the response. Real web applications are loading 10s of URLs for each button click or transaction and HTTP Scoop shows you the whole conversation.

I develop Web 2.0 applications for a living and I have to say, HTTPScoop ROCKS! No more trying to piece together tcp dumps and stuff split across multiple packets. No more trying to get Firebug to stick around and keep analyzing during various redirects. This thing just works, and it works well! Three thumbs up!

I've been looking for something easier to use than Ethereal when debugging HTTP server requests and HTTP Scoop seems to fit the bill. It works right out of the box (for example, it correctly chose the en1 interface on my Airport connected laptop rather than making me figure that out) and it automatically captures and decodes HTTP traffic as advertised. It shows as much detail about each request as anyone could wish for from the complete headers down to the TCP/IP protocol exchange. There are some user interface oddities but polish is a lot easier to add than basic functionality which the app already has.

Excellent advice. For those who don't know, your Mac has TONS of useful, free, unix programs available.

However, tcpflow isn't one of them (at least not for the client versions of Tiger). To get a copy for yourself visit: http://www.entropy.ch/software/macosx/#tcpflow

Being familiar with tools such as tcpflow/tcpdump/ethereal etc. gives you another important benefit too: portability. You can use them in the same way whether you're sitting in front of an OS X, Linux, Solaris or HP-UX box and whether or not you have a window manager available. You also don't need to be sitting near the box you're monitoring - you just telnet/ssh over there and execute the capture remotely.

However, none of these tools fully decode HTTP. Say you want to see what HTML your webserver or appserver is spitting out, but the server's using GZIP content encoding. You'll just get gibberish being printed out.

Try doing 'sudo tcpflow -c' and point your browser at slashdot.org or google.com and you'll see what I mean!

As well as extra decoding, HTTP Scoop gives you a UI which does things like HTML/XML syntax highlighting, hex dumps etc. Maybe not essential, but nice to have.

I'm not knocking tcpflow etc; just pointing out that they're different tools for different jobs... but then again, I'm not entirely unbiased ;-)
