Ultra-fast API JSON Visualizer • Works Offline • Open Source
RouteGrid takes any JSON file containing API structure and automatically extracts:
- GET / POST / PUT / DELETE endpoints
- URL paths
- Query parameters
- Body schema
- Headers
- Groups & sections
- Summary info
It’s like Swagger — but lightweight, offline, and instant.
- Paste JSON or upload a
.jsonfile - RouteGrid analyzes it
- Endpoints appear beautifully grouped
- You explore your API visually
- (Pro) Export as docs
Pro unlocks:
- Export to PDF, HTML, Markdown, Notion
- API Spec Validator
- Example Generator
- Serverless Fetch: Paste an API URL → fetch → visualize
- Advanced UI Themes
- Private Mode (Password Protected)
Pro is optional — core RouteGrid stays 100% free and open source.
