Intercepta is a Chrome extension designed for frontend developers and QA testers, enabling the interception and mocking of HTTP requests with user-defined rules. This tool eliminates the dependency on backend APIs by allowing users to simulate API responses, including error conditions, thus facilitating uninterrupted development and testing. It supports various HTTP methods such as GET, POST, PUT, and DELETE, making it versatile for different use cases.

The application features a user-friendly dashboard for managing mock rules, with options for context-aware activation based on specific websites. Users can define custom response bodies in formats such as JSON, HTML, or Text, with built-in handling for common CORS and CSP issues. Intercepta promises to enhance the development cycle by allowing seamless testing of various scenarios, ensuring that demos run smoothly with predictable data.
