Giving structure to chaotic data.
We started JSON Viewer with a simple belief: reading deeply nested brackets in terminal logs wastes engineering hours. Data should be visible, navigable, and beautiful.
Visual First
Graph topologies reveal dependencies, null pointer bugs, and schema mismatches that raw text editors obscure.
Zero-Leak Privacy
Your payloads remain in your browser sandbox. We never send confidential database schemas to cloud databases.
Agent Ecosystem
Built from the ground up for the AI era with Model Context Protocol (MCP) support for Claude, Cursor, and Zed.
How developers use the studio
Paste JSON, YAML, CSV, or pass external API endpoints.
Switch between interactive graph, key tree, or tabular matrix.
Catch schema errors, inspect properties, or diff versions.
Download SVG/PNG, generate read-only links, or embed in Notion.
Built with open source love
We extend our heartfelt gratitude to the open-source creators behind ELK layout algorithms, Next.js, React, Tailwind CSS, Monaco Editor, and Lucide icons.
