Auth HI! is a Chrome extension designed for developers who need to streamline the process of injecting authentication headers into HTTP requests. This free add-on allows users to automatically add Authorization headers based on URL patterns, facilitating seamless development and testing. With features such as bearer token injection, URL pattern matching, and the ability to manage multiple rules, it caters specifically to the needs of developers working with various environments.

The user-friendly side panel interface remains open while browsing, providing real-time tracking of active rules and request counts. Auth HI! prioritizes privacy and security by storing all data locally on the device, with no external servers involved. As an open-source tool, users can audit the code themselves, ensuring transparency and trust. Ideal for debugging authenticated requests, this extension eliminates the need for manual header modification in development tools.
