From Fiddler Classic to Fiddler Everywhere: Modern Cross-Platform Debugging

From Fiddler Classic to Fiddler Everywhere: Modern Cross-Platform Debugging

Progress® Telerik® Fiddler™ Classic has been part of developers' workflows for years. But as applications, protocols and development environments evolve, even our favorite tools can start showing their age.

Join Progress' Jeff Fritz, Product Manager Teodora Genova, and Fiddler Ambassador Robert Boedigheimer for an honest conversation about the transition from Fiddler Classic to Fiddler Everywhere.

Robert will share his own journey as a long-time Fiddler Classic user: what kept him on Classic for so long, what challenges he started running into and what ultimately convinced him to make the switch.

Along the way, we'll demonstrate how familiar workflows such as Rules, Composer and breakpoints translate to Progress® Telerik® Fiddler™ Everywhere and how it supports modern protocols including HTTP/2 traffic capture and inspection.

We’ll walk through the migration process and explore newer capabilities like Fiddler MCP and Agent Cache that enable modern development and AI-assisted debugging workflows.

Attendees Will Learn

  • Why Fiddler Everywhere is the path forward for cross-platform debugging
  • How to capture, inspect and troubleshoot HTTP/2 traffic with Fiddler Everywhere
  • How to migrate from Classic using the Fiddler wizard
  • How Classic features map to Fiddler Everywhere
  • How to use Rules, Composer and breakpoints in real debugging workflows
  • About the new and upcoming features designed to make debugging even more efficient
