Zod Schema Builder

Build type-safe Zod schemas with visual field configuration, validation rules, nested objects/arrays, schema testing, and automatic name sanitization. Export as Zod or JSON format.

Build Your Schema

No fields added yet. Click "Add Field" to start building your schema.

Field names can contain letters, numbers, and underscores (a-z, A-Z, 0-9, _)

Examples: user_name, first_name, address_line_1, _privateField

Generated Schema

Tips:

  • Edit the Zod schema directly and click the save icon to update the visual builder
  • Field names are automatically sanitized (spaces → underscores, special chars removed)
  • All fields are required by default - uncheck "Required" to make them optional
  • Use "Nullable" to allow null values in addition to the field type

Test Your Schema

Test your data against the generated schema to see validation results:
