Smart type inference

Automatically maps JSON types to Prisma: String, Int, Float, Boolean, DateTime, and nested model relations.

Your data never leaves the browser. Safely convert real schemas and sensitive data structures.

Relations & decorators

Detects nested objects as related models, arrays as one-to-many, and adds @id, @default, @unique where appropriate.
