Features & Specs

  1. Easy HTTP Header Modification

    ModHeader allows users to easily add, modify, or remove HTTP request and response headers directly from the browser without needing to write code or set up a proxy server.

  2. User-Friendly Interface

    The extension provides a simple, intuitive UI where users can create profiles, toggle headers on/off, and manage multiple header configurations with minimal technical knowledge.

  3. Profile Management

    Users can save multiple header profiles for different testing scenarios (e.g., different environments, authentication tokens, or user agents) and switch between them quickly.

  4. Cross-Browser Support

    ModHeader is available for major browsers including Chrome, Firefox, and Edge, making it versatile for developers who work across different browser environments.

  5. Useful for Development and Testing

    It's particularly helpful for developers and QA testers who need to simulate different API keys, test CORS configurations, spoof user agents, or debug header-related issues without modifying server code.

Comparing Charles Proxy, Fiddler, Wireshark, and Requestly
On the pricing front, Requestly strikes a balance between affordability and functionality. It is an open-source tool, offering freemium to individual developers and affordable pricing plans for team collaboration. We have also clearly differentiated how Requestly differs from Wireshark and other web debugging tools like Proxyman, Modheader, and HTTP ToolKit separately.
