Fiddler free for windows 10

Fiddler is a web debugging proxy tool for Mac, Windows, and Linux devices. Fiddler allows you to test applications, not just browsers, for bugs. You can even mock requests from applications or modify them, without changing the code, to test any type of app request. In addition to debugging on Windows, Mac, and Linux devices, you can also debug on mobile phones both iOS and Android.

There is also a Chrome extension you can use for troubleshooting. 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.

It allows you to see whether your web application is giving errors and fix them. For example, it allows you to test mobile apps and desktop apps that are not browsers. In addition, there are many more features that you can make use of when using Fiddler or a Fiddler alternative. You can mock requests, as mentioned before, or intercept requests. Fiddler is not the only web traffic monitoring tool out there.

Some people have reported that they could not get Fiddler to monitor all network traffic, for example. If you want to capture that traffic, or if you want to view errors below the HTTP level, you might be in need of another tool. Regardless of why you are unsatisfied with Fiddler, however, there are many great Fiddler alternatives out there you can use.

In this article, I will show you the 10 best Fiddler alternatives for debugging and network monitoring. Let us get into it. Wireshark is one of the most widely used, if not the most widely used, network protocol analyzers in the world.

If you think there are bugs or errors below the HTTP level, it will be hard to capture them in Fiddler. In that case, Wireshark will come to the rescue. Since Wireshark can capture any type of network packet, you can get a lot more information out of it than out of Fiddler. Think of it as different levels in a pyramid. You can inspect hundreds of protocols using Wireshark and make use of offline analysis. It also supports a wide range of capture file formats. Another benefit of using Wireshark over Fiddler is that Wireshark is open source.

While Fiddler is freeware, meaning you can use it for free, Wireshark allows you to browse and modify the source code to better fit your needs, giving you more flexibility. I also really liked the amazing community behind the project, as well as the vast range of resources available.

For example, there is on-demand Wireshark training on the website to help you get acquainted with the tool, as well as educational conferences and private training. On GitLab , you can view the source code and track issues and bugs.

All in all, Wireshark is a strong alternative to Fiddler, with a number of benefits, including being open source and offering the ability to capture errors below the HTTP level. Explore : Best BrowserStack Alternatives.

However, Charles does have a number of benefits over Fiddler. You can use the Charles proxy to simulate slower internet connections. This way, you can discover errors and bugs that occur during such connections. That is made possible with the Bandwidth Throttling tool, which allows you to adjust the bandwidth to any number of bytes per second to land on the exact speed you want to test for.

Many people love the Mirror tool, which is another advantage Charles has over Fiddler. The Mirror tool saves responses to a disk, creating a mirror copy of the website you are browsing.

Alternatively, you can click on any node in Charles to save a mirror copy to the disk. However, unlike the Mirror tool, which is not restricted by Recording Settings limits, this alternative is. Charles has many other useful tools as well, such as the Autosave tool, which saves and clears the recording session at a specific interval, which can be useful during longer recording spans.

There is also the Block Cookies too, which blocks cookies in network requests. It can be used for two main purposes:. The Rewrite tool allows you to modify requests by rewriting them.

With the Pro version, you can run tests with automated mock responses. HTTP Toolkit is simple and easy to use, and being that it is open source, you can view the source code on GitHub and edit it.

However, there is a Pro version as well, which is not open source. The Pro version will give you access to special features such as automated mock responses. With the Pro version, you can also do things like redirect requests to another server, inject timeouts, simulate connection failures, set advanced customizations, and more.

Always check the Pro page for updated pricing information. Proxyman is a web debugging tool for Mac devices. Proxyman acts as a man-in-the-middle proxy to log traffic flowing from and to your applications and the SSL server. You can modify requests and responses by using the Breakpoint Tool to stop a request before it goes to the server or stop a response before it goes to your application. You can also use the scripting tool to use JavaScript to monitor network traffic, including both requests and responses.

You can highlight certain requests or add comments, as well as use a wide range of filters during your testing. Some people have reported experiencing difficulty using Fiddler to capture mobile traffic, so you can use Proxyman for that instead.

With Proxyman, you can capture traffic not only from simulators but from real Android and iOS devices as well. Proxyman does require you to purchase a license before using the software. However, the license is a perpetual license, though you will need to renew it if you want to receive updates after a year.

In other words, the license gives you access to the software for as long as you want, with one year of free updates. Always refer to the pricing page to see what the software costs in real time, as prices are subject to change at any time.

It is important to note that the last version of SmartSniff was released in You should still use it if you have an older machine, as not a lot of options exist for such machines.

Also, SmartSniff is available in multiple languages, but the other language versions may not have been updated as frequently. For example, although the Traditional Chinese, Brazilian Portuguese, French, and German versions were last released in , the Galician version was released way back in and may no longer work well.

It is a great tool for documenting errors that occur while connecting to and integrating with third-party systems. You can isolate and fix performance bottlenecks, discover undocumented features that occur when integrating with third-party applications, detect fake authentication and other security issues, decrypt SSL traffic from any application or browser including Android emulators , and more.

This way, you can analyze the data again later. By creating highlighting rules, you can highlight specific errors or slowdowns. You can also visualize your traffic using the charts the tool gives you.

HTTP Debugger is not free, but the license is affordable and allows you to use the software for as long as you want, with free updates for up to a year and free tech support. For example, you will get a 10 percent discount if you buy licenses and a 25 percent discount if you buy 50 or more licenses.

In addition, you can also debug local traffic on private networks, including web servers, iOS devices, Android devices, simulators, and emulators. Both basic and advanced filters can be applied when analyzing traffic. InProxy is entirely free to use.

Bins are private by default, but you can also create a public bin if you want. Other events you can collect in your bin include RSS feeds, GitHub activity on a specific repository, and more, but that is not the focus of this article. One of the benefits of using Surge is that it offers a high-performance experience, with low system resource consumption on your end, but with the ability to run without interruption with excellent performance.
