Fiddler Web Debugger Turns 20

Twenty years ago (!!?!) was the first official release of Fiddler. I still run Fiddler for some task or another almost every working day. I still run my version (Fiddler Classic) although some of the newer tools in the Fiddler Universe are compelling for non-Windows platforms.

I presented some slides in a birthday celebration that Progress Telerik streamed online this morning. Those slides might not make sense without the audio, but most of the content is in a presentation I gave at the Codemash conference, and I’ve shared the slides and audio from that talk.

For decades, Fiddler has been a huge part of not only my professional life, but my personal life as well, so this milestone is a bittersweet one. I could write pages, but I won’t. Maybe some day.

Happy birthday, Fiddler, and thank you to everyone who has joined me on the journey over the decades!

-Eric

  1. Wow – 20 years already! I used it a lot for many years of my career – thanks for creating it Eric.

  2. Couldn’t agree more, thank you and congrats! Just used Fiddler today, in fact… trying to play with the Origin header. It’s an amazing tool that Just Works. Oh, and you had such a good idea to design for extensions early on, too! I always try to spread the good word about it to coworkers… along with your blog content. Take care
