WebAuthn DevTools is a free Chrome extension designed for developers working with the WebAuthn API. It provides a dedicated pane within Chrome's Developer Tools, allowing users to capture and inspect API calls in real-time. This functionality is essential for auditing both the input and output of WebAuthn API requests, making it easier to debug and optimize authentication flows.

One of the standout features of WebAuthn DevTools is its ability to parse encoded or hashed payloads, giving developers insight into their contents. This detailed inspection capability enhances the debugging process and helps ensure that the implementation of WebAuthn is secure and effective. Importantly, the extension respects user privacy by not collecting or transmitting any information to external servers.
