A Python library implementing the JSON Schema specification for validating JSON data against schemas. It supports all major JSON Schema drafts from Draft 3 through Draft 2020-12.
Use cases
- validate payloads against a schema
- check api request bodies conform to a spec
- validate config files with schema
- ensure documents match expected structure
- validate data loaded from files in python
When to choose
- you need standards-compliant JSON Schema validation in Python
- you need support for multiple JSON Schema drafts including 2020-12
- you want detailed validation error reporting
When to avoid
- you need validation of non-JSON data formats
- you need a language-agnostic validator outside Python
- you need extremely high-throughput validation with minimal overhead
