HTTP Toolkit

HTTP Toolkit gives you a clear view of what's happening behind the scenes when you surf the web. It captures and analyzes all HTTP traffic from your browser and other sources, and it places the information neatly in front of you in a well-organized manner. The program is an excellent solution for programmers who need to build, debug and test with HTTP(S). It doesn't burden you with overcrowded menus and complicated options so you can run your tests on the fly.

The software is free and open source, but a paid Pro version is available as well. You can download the setup package and install its components in less than a minute, on any modern Windows platform. Also, there is no need to install any prerequisite tools or services, and you don't have to sacrifice too many resources to run the program.

You can start using the program right away, without the need for any complicated setup. You can launch a new Google Chrome window from HTTP Toolkit's main user interface, after which you may connect to what you wish to test. The program will capture every bit of incoming and outgoing HTTP traffic and display it on the same interface, in a different section.

The captured HTTP requests are displayed in a list, along with a few details, like request type, status, source, host, path and query. What's more, the software presents an in-depth analysis of each request, which includes the full URL, headers, response body and more. What's more, each analysis section can be collapsed to make everything more comfortable to read. Also, some of them come with options for different view modes. For example, you can view the response body as Javascript, plain text or HEX values.

Besides intercepting your browser's traffic, HTTP Toolkit can capture it from other sources as well, like mobile devices, dockers, computers on your network, virtual machines and many others. The software has separate modules for the supported sources, but, at the time of writing, most of them are marked as "coming soon".

It's hard to think about better and more efficient solutions than HTTP Toolkit when it comes to HTTP traffic analysis.
