JSON Crack

Visualize JSON pages as an interactive graph. Toggle between raw text and an auto-generated diagram.

JSON Crack turns any JSON page you visit into an interactive, zoomable graph — no copy-pasting into a separate tool. When you open a URL that returns JSON (an API response, a .json file, a config endpoint), JSON Crack adds a toggle that lets you switch between the browser's raw text view and an auto-generated node diagram. Collapse branches, follow relationships, and read deeply nested structures at a glance. Features: • One-click toggle between raw JSON and graph view • Works on any page that serves JSON — public APIs, localhost, internal tools • Pan, zoom, and collapse nodes to explore large payloads • Fully local — your JSON never leaves the browser • Free and open source (github.com/AykutSarac/jsoncrack.com) Built for developers who spend their day staring at API responses and want a faster way to understand the shape of their data.
