How to Start Your Fiddler Journey
- Try the Fiddler product(s) that aligns with your needs.
- Integrate Fiddler into your workflow for rapid, elegant debugging and troubleshooting.
- You’ll start realizing the high value of benefits of the app through the acceleration of both your time and cost savings.
Web Debugging
Debug traffic from PC, Mac, or Linux systems and mobile devices. Ensure the proper cookies, headers, and cache directives are transferred between the client and the server. Supports any framework, including .NET, Java, Ruby, etc.
Performance Testing
It lets you see the “total page weight,” HTTP caching and compression at a glance. Isolate performance bottlenecks with rules like “Flag any uncompressed responses larger than 25kb.”
HTTP/HTTPS Traffic Recording
The app is a free web debugging proxy which logs all HTTP(s) traffic between your computer and the Internet. Use it to debug traffic from virtually any application that supports a proxy like IE, Chrome, Safari, Firefox, Opera, and more.
Web Session Manipulation
Easily manipulate and edit web sessions. All you need to do is set a breakpoint to pause the processing of the session and permit alteration of the request/response. You can also compose your own HTTP requests to run through the tool.
Security Testing
Use the program for security testing your web applications -- decrypt HTTPS traffic, and display and modify requests using a man-in-the-middle decryption technique. Configure the app to decrypt all traffic or only specific sessions.
Customizing Telerik Fiddler
Benefit from a rich extensibility model, ranging from simple FiddlerScript to powerful Extensions which can be developed using any .NET language.
