About TypeScout

TypeScout is the ultimate companion for frontend developers who work with TypeScript. Stop manually typing interfaces or pasting JSON into online converters. With TypeScout, you can generate strict, production-ready TypeScript interfaces directly from your Chrome DevTools Network tab. Why TypeScout? Every time you integrate an API, you need to define the response types. TypeScout automates this completely. Just open the "TypeScout" panel in DevTools, click on any JSON request, and get the perfect interface instantly. Key Features: Instant Conversion: Transforms JSON network responses into strictly typed TypeScript interfaces on the fly. Split View: See the raw JSON alongside the generated TypeScript for easy verification. Smart Naming: Automatically generates PascalCase interface names (e.g., UserId, ProductItem) and handles duplicates intelligently. Privacy First: All conversion happens locally in your browser. No data is ever sent to any server. Modern UI: A clean, dark-mode interface that feels native to Chrome DevTools. One-Click Copy: copy the result to your clipboard and paste it straight into your codebase. How to use: Open Chrome DevTools (F12 or Cmd+Opt+I). Navigate to the TypeScout tab. Browse your app; network requests will appear in the sidebar. Click any request to generate its TypeScript interface immediately. Perfect for: React / Vue / Angular developers using TypeScript. Debugging API responses. Rapidly prototyping new features.
