Description
Modify HTTP request headers with clean card-based controls. This extension helps users quickly modify, add, remove, and manage HTTP request headers directly in the browser. It is useful for developers, testers, QA engineers, and technical users who need to simulate different environments, debug APIs, test authentication flows, or verify how websites behave under specific header conditions. It is especially valuable for: 1. Add custom headers such as authorization tokens, environment flags, locale settings, or experiment identifiers. 2. Simulate different request scenarios without changing code or redeploying services. 3. Quickly verify how a website behaves under different headers, user states, or regional configurations. 4. Save commonly used header rules and reuse them across testing sessions. 5. Perform header modifications directly in Chrome without installing heavy proxy software.
