Offline Mode
The offline mode in Fiddler Everywhere allows you to use the application’s core functionalities while working with limited or no internet access. The mode enables you to start the application without an explicit login and then configure the capturing you want to use - all without having active internet connection or while using restricted network. All options that can help you in your traffic debugging process are available offline, such as all Inspectors, Filters, Rules, Compare Sessions, and Composer.
Prerequisites
- Requires licensed seat under the Fiddler Everywhere Enterprise subscription tier.
- Supported on Windows for both physical and virtual work machines.
- (Windows only) Requires Active Directory configuration with valid AD user (AD principal email).
- Supported on macOS with limited support for JAMF users only.
