This tool integrates directly into the browser, allowing users to test API endpoints and inspect responses without needing to switch applications. Its side panel interface enhances convenience, enabling users to manage requests and view results seamlessly.

Key features include quick method switching between GET and POST, dynamic header management, and full control over POST body content. The smart response viewer formats JSON and other response types for easy reading, while the clean interface supports both light and dark modes. API Relay simplifies the API testing process, making it an indispensable tool for anyone involved in web development.
