Which Should You Choose?

Choose Auth0 if:

  • •User authentication - login, MFA, SSO, and user management - is the requirement
  • •You need a managed identity service with compliance and enterprise features
  • •Authentication is a business requirement that needs SLA guarantees

Choose Zod if:

  • •You need runtime type validation and schema parsing in TypeScript or JavaScript
  • •Validating API request bodies, form data, and environment variables with a great DX is the goal
  • •You want a free, lightweight library with excellent TypeScript inference

Auth0 is a paid managed service; Zod is a free open-source TypeScript validation library. No competition. Zod costs nothing and is a standard part of TypeScript stacks. Auth0 costs from $0 to $23/month+. You'd use both: Zod to validate the data coming into your API, Auth0 to verify the user making the request.
