A TypeScript library that converts Zod schemas into JSON Schema documents, with support for recursive $refs, OpenAPI 3.0 targeting, and OpenAI strict mode. It is deprecated as of November 2025 in favor of Zod v4's native JSON Schema support.

Use cases

• convert zod schemas to schema
• generate schema from zod validation types
• produce openapi 3.0 schemas from zod
• create openai strict mode schemas from zod
• share api request validation schemas as schema
• resolve recursive zod schemas into schema refs

When to choose

• you are on Zod v3 and need JSON Schema output
• you need OpenAPI 3.0 or OpenAI strict mode compatible schemas
• you cannot yet migrate to Zod v4

When to avoid

• you are using Zod v4, which natively generates JSON schemas
• you need a long-term maintained dependency
• you need conversions in the other direction (use -schema-to-zod)
