Show HN: Built a zero config proxy that lets Claude control your React App (github.com)

A developer has introduced Z1, a zero-config proxy tool that enables Claude Code to interactively control and test React applications in real time without any changes to the codebase. This innovative setup allows users to simulate various scenarios such as error states and loading conditions by simply instructing Claude to intercept, delay, or modify HTTP requests flowing between the browser and the development server. The tool also facilitates end-to-end testing by capturing request details and providing insights into the React component tree, all through a lightweight browser panel. This advancement is significant for the AI/ML community as it demonstrates the potential of AI-driven automation in software testing and debugging. By merging Claude's reasoning capabilities with live application data, Z1 enhances the development workflow, enabling developers to identify and fix bugs directly. Key features include the ability to read browser console output, manipulate request parameters, and inspect the state of React components without altering the app’s initial setup, thus streamlining the testing process and encouraging more efficient, data-driven development.
