About API Mock & Intercept Tool

This extension provides API request interception and mocking capabilities exclusively for localhost development environments. Its sole purpose is to help developers test web applications by creating mock API responses without modifying backend code. - Intercept HTTP/HTTPS requests on localhost (localhost, 127.0.0.1) - Create custom mock responses with configurable status codes and JSON data - Override real API responses with test data for different scenarios - Monitor and capture network requests in real-time - Test error handling and edge cases by simulating various response conditions - Add delays to simulate network latency. This is purely a development tool focused on simplifying API testing during local application development.
