#json-schema

schemaui turns JSON Schema documents into fully interactive terminal UIs powered by ratatui, crossterm, and jsonschema. The library parses rich schemas (nested sections, $ref, arrays, key/value maps, pattern properties…) into a navigable form tree, renders it as a keyboard-first editor, and validates the result after every edit
