The Fiddler family of products continues to evolve. What started as a community web debugging proxy for Windows has expanded to the comprehensive product line of web debugging and support troubleshooting solutions.

Whether you are an engineer, support team agent, quality assurance analyst, or non-technical team member, the Fiddler ecosystem has a product that aligns with your needs.

Every Fiddler product is engineered to match unique requirements and deliver benefits, including time and cost savings, along with a host of others in between. While we work to provide even more value to you, here’s an FAQ resource the team put together based on community inquiries.

My data is sensitive; how does Fiddler use my data?

It does not. Your data is protected and remains with you. Fiddler will never store your data.

What Is Licensing Model for Fiddler Everywhere and FiddlerCore?

Fiddler Everywhere: Per seat, meaning one specifically named user for both monthly and annual subscriptions. Additional seats may be purchased on a per-user basis.

What is the difference between Fiddler Classic and Fiddler Everywhere?
