json-schema-faker

Generate valid JSON mock data from JSON Schema definitions. v0.6.2 supports JSON Schema 2019-09 and 2020-12 with deterministic output via seeded PRNG (Mulberry32). Zero production dependencies. Key differentiators: built-in format generators (email, uuid, etc.), extension support for faker/chance, custom keywords via define(), and sequential auto-incrementing seeds via createGenerator().
