    A powerful, visual GUI for developers to create and manage JSON Schemas, with first-class support for OpenAI and LLM function calling definitions. (by anusarati)

    Project mention: Show HN: Open-source GUI editor for JSON and function call schema | news.ycombinator.com | 2025-07-15

    I was working on function call schema for my AI startup recently, but I didn't have a good workflow, so I made a GUI editor to make it easier and faster to write JSON schema. It shows what annotations you can give to each property in case you aren't familiar with JSON schema keywords, so it's very user-friendly.

    It also enforces the correct structure for the different types like "function" and "object", so you can't make syntax or structural errors. Cursor didn't use the OpenAI format when I auto-completed a {"type": "function"} schema, but this isn't a problem using my tool.

    Why use this over Pydantic? It's a lot more visual, and you can reorder properties and change "required" properties without wrangling with text, so it's easier when you're in the prototyping stage.

    The source is at https://github.com/anusarati/json-schema-builder.
