A Go library for validating JSON documents against JSON Schema, supporting drafts 4, 6, 7, 2019-09, and 2020-12 with full test-suite compliance. It offers extensible vocabularies, custom formats, content assertions, introspectable hierarchical errors, and infinite-loop detection.

Use cases

• validate payloads against a schema in go
• check api request bodies conform to a schema
• validate config files with draft 2020-12 schemas
• register custom formats and vocabularies for schema validation
• get detailed structured validation errors for debugging
• validate base64-encoded or content assertions

When to choose

• you need a spec-compliant JSON Schema validator in Go across multiple drafts
• you need custom vocabularies, formats, or regex engines
• you need introspectable, hierarchical validation error output

When to avoid

• you need schema validation in a language other than Go
• you need JSON Schema code generation rather than runtime validation
