So, what does Wireshark do? What are the benefits of using it? HTTP is at the top of the pyramid, but there are levels below it that Fiddler won’t be able to capture. Think of it as different levels in a pyramid. Since Wireshark can capture any type of network packet, you can get a lot more information out of it than out of Fiddler.

Wireshark can help you discover server bugs, bugs in the TCP/IP protocol that the browser uses, and layers below that. In that case, Wireshark will come to the rescue. If you think there are bugs or errors below the HTTP level, it will be hard to capture them in Fiddler. Wireshark is one of the most widely used, if not the most widely used, network protocol analyzers in the world.Īs mentioned, Fiddler is an HTTP and HTTPS proxy. Let us get into it.Īlso Read: Best Open Source Tools For Web Developers The 10 Best Fiddler Alternatives 1.

You can always use your browser’s built-in inspector mode for some debugging solutions, but not all. It allows you to see whether your web application is giving errors and fix them. To put it in more layman terms, Fiddler allows you to analyze and monitor web traffic to ensure everything is going smoothly, cookies are being transferred, and so on. There is also a Chrome extension you can use for troubleshooting.
