API Homie is a Chrome add-on designed to simplify the process of debugging API requests for developers. This free tool allows users to capture and inspect API requests, including fetch and XMLHttpRequest, providing detailed information about request and response headers, bodies, and statuses. Key features include a user-friendly interface for monitoring failed requests, filtering by HTTP methods, and an X-Ray mode that visually connects API response data to DOM elements, making it easier to trace data flow in applications.

In addition to its inspection capabilities, API Homie offers a Mock Manager that enables users to create custom mock responses for testing various scenarios without altering backend services. The tool supports exporting requests as cURL commands or Fetch code and can generate TypeScript interfaces from API responses. With a focus on privacy, all data is stored locally on the user's device, ensuring compliance with security standards. The free version allows for a limited number of requests, while the Pro version offers expanded capabilities for a one-time fee.
