API Snitch is a Chrome add-on designed to simplify the process of recording API calls and generating TypeScript client code. This free tool captures network requests from any website using Chrome's Debugger API, allowing users to record their interactions with web applications. With a user-friendly interface, users can easily start and stop recording, inspect detailed request headers, and view response bodies with syntax highlighting. API Snitch supports filtering by HTTP method and content type, making it easier to manage captured requests.

One of the standout features of API Snitch is its ability to automatically generate fully-typed API client functions based on the recorded requests. It infers TypeScript interfaces from actual responses, ensuring that the generated code is production-ready. Additionally, the tool includes secret detection capabilities, identifying sensitive information in API calls and offering options to replace them with environment variables. Users can test the generated code in a sandboxed environment before downloading a complete project, which includes essential files like package.json and tsconfig.json.
