Turning nested JSON into a live node graph with bidirectional edits actually pays off — double‑click a node to change a value and the raw JSON updates instantly (and vice versa). It’s entirely client‑side for privacy, generates TypeScript interfaces on the fly, and is MIT‑licensed; next steps should focus on UX and performance for massive payloads and clearer import/export flows.
Everything important runs in the browser: JSON formatters, a JWT debugger explicitly marked 100% client-side, and a new Database Design Studio that turns SQL/Prisma schemas into draggable ER diagrams you can export as PNG. The product’s hook is convenience plus privacy — a single place to grab many small tools without sending snippets to a server. It’s useful and nicely designed, but the core idea is a well-curated bundle rather than a novel technical breakthrough.
