JSON Schema validation and tools

35 repos

Libraries, validators, and tooling for JSON Schema specification across multiple languages. This cluster covers schema validation engines (jsonschema, schemasafe, msgspec), schema generation and serialization (Newtonsoft.Json.Schema, pydantic), and the JSON Schema specification itself. Most repos are Python and TypeScript implementations focused on validating JSON data against formal schemas, with applications ranging from API validation to data serialization and type-safe code generation.
