Webber

Webber is a powerful and useful development tool designed from the get-go to make it as simple as possible for you to monitor and debug HTTP and HTTPS traffic sessions between the Internet and your computer.

Easy to install and to get started with

To put it even simpler, with the help of this utility, you can thoroughly inspect the requests, responses, and the headers, as well as simulate traffic by applying latency and bandwidth throttling.
Before anything, you should make sure that Java is present on your computer's system. Other than that, you should be able to deploy the app on your computer's system without any types of problems thanks to a streamlined and typical installer.

Effortlessly monitor and debug HTTP and HTTPS traffic

The app boasts a simplistic and very intuitive user interface, with a standard top toolbar that provides you with quick access to all the app's controls and features.  To get started, you are required to first make sure that your client app (or your web browser) has the appropriate proxy settings. Once this is dealt with, simply click the 'Record' button from the aforementioned top toolbar and Webber automatically starts to log the traffic.
The recorded information is neatly displayed in three main self-explanatory tabs, General, Content, and Notes. Of course, the app provides you with the possibility to filter out unrelated traffic, to inspect requests and responses by taking advantage of the syntax highlight viewer, to simulate real-life network traffic and even analyze the performance with the help of HAR files.

A powerful and widely-accessible web debugging proxy utility

To conclude, Webber is a reliable and surprisingly novice-friendly application that allows you to thoroughly record, view and inspect all HTTP and HTTP traffic sessions. The app is easy to install, fairly light on your computer's resources and manages to strike a perfect balance between the number of features and usability.
