Questions & Answers

As answered by people managing JSON Utility and GitLab.

What makes your product unique?

JSON Utility's answer

  • Runs entirely in the browser — no file is ever uploaded to a server
  • No account or signup required, unlike many competing JSON tools
  • Includes a batch schema validator for checking many files against one schema at once
  • Includes a dedicated AI tool-calling schema validator for OpenAI function calling and Anthropic tool use — a feature few if any JSON tools offer

Why should a person choose your product over its competitors?

JSON Utility's answer

  • Free, with no signup and no data ever leaving your browser
  • Covers more ground than most single-purpose JSON tools: validation, conversion, diffing, JSONPath queries, JSON Schema validation, and AI tool-calling schema validation — all in one place
  • Built to stay responsive even on large, multi-megabyte files, where many browser-based tools freeze or crash

How would you describe the primary audience of your product?

JSON Utility's answer

  • Backend and frontend developers working with JSON, YAML, and XML data day-to-day
  • API integrators and QA engineers who need to validate or diff data quickly
  • Developers building on LLM tool-calling APIs (OpenAI function calling, Anthropic tool use) who need to validate their schemas before deploying

What's the story behind your product?

JSON Utility's answer

It started as a simple JSON validator/formatter and grew into a full toolkit as more everyday developer needs came up — conversion between formats, diffing, JSONPath querying, and schema validation.

The AI tool-calling schema validator was added as more developers began building agents and needed a fast, offline way to sanity-check tool definitions before wiring them into a live model.

Which are the primary technologies used for building your product?

JSON Utility's answer

  • React, Vite, and React Router on the frontend
  • Ajv for JSON Schema compilation and validation
  • Fully static, server-side prerendered HTML per route, deployed on Vercel — no backend server, since every tool runs client-side

Who are some of the biggest customers of your product?

JSON Utility's answer

JSON Utility is a free, anonymous tool with no signup — we don't track or identify specific customer organizations. It's used by individual developers and small teams across the industry.
