About DevCanvas - The Developer Toolkit
```
DevCanvas is a free, privacy-first developer toolkit that detects raw JSON responses in your browser and lets you format, visualize, and convert them in one click.
π AUTO-DETECT JSON IN YOUR BROWSER
When you navigate to a URL that returns raw JSON (like a REST API endpoint), DevCanvas automatically adds a floating "Format in DevCanvas" button. Click it and the payload is securely transferred to devcanvas.net β no copy-pasting required.
β‘ CORE FEATURES
β’ JSON Formatter & Beautifier β Instantly format minified JSON with proper indentation
β’ Interactive Tree Viewer β Explore deeply nested objects with a collapsible visual tree
β’ JSON to TypeScript β Auto-generate TypeScript interfaces from any JSON or YAML payload
β’ YAML Support β Paste YAML configs and get JSON output or TypeScript types instantly
β’ JSON Diff Viewer β Side-by-side comparison powered by Monaco's diff engine
β’ Local History β Save payloads to browser storage and recall them anytime
π PRIVACY FIRST
All processing happens 100% locally in your browser. Your data never leaves your machine β no servers, no tracking, no analytics on your payloads.
π HOW IT WORKS
1. Browse to any raw JSON API (e.g. https://api.github.com/users)
2. Click the floating "Format in DevCanvas" button
3. DevCanvas opens in a new tab with your data already loaded
4. Format, visualize, diff, or generate types β all instantly
π‘ PERFECT FOR
β’ Frontend & backend engineers working with REST APIs
β’ DevOps teams inspecting Kubernetes / Docker YAML configs
