The author bears no responsibility for misuse. Most web apps have a perfectly good API. It's just hidden behind the frontend and undocumented. CLI-Anything-Web makes it usable - fully automatically. What it does Give it a URL. The Claude Code plugin navigates the app autonomously using Playwright, records all HTTP traffic, and generates a complete pip-installable Python CLI. No human interaction. No reading minified JS. The pipeline Capture - A Playwright browser session navigates the target app autonomously, recording all HTTP calls. It also detects the framework (Next.js, React SPA, SSR) and any anti-bot protection (Cloudflare, WAF) that will affect how the CLI needs to make requests later. Analyze - The traffic is classified by protocol: REST, GraphQL, Google's batchexecute, or raw SSR HTML. Each maps to a different CLI architectu
