}About Prisma Schema Generator
Adopting Prisma on an existing project means recreating your current database structure as a schema file, model by model. Hand-writing every model, field type, relation, and attribute is tedious and error-prone, especially across a large database. The Prisma Schema Generator takes your existing structure and produces a Prisma schema with models, fields, and relationships mapped out, giving you a solid starting point in seconds rather than hours.
Provide your database structure and the tool generates the corresponding `schema.prisma` definitions, translating tables into models and columns into typed fields. It works in your browser with no signup and no watermark, and your schema details never leave your machine. That keeps internal table and column names private while saving you the grind of transcribing a database into Prisma syntax by hand.
Common uses
- Migrating a legacy database to Prisma without hand-writing every model.
- Bootstrapping a schema.prisma file from an existing table structure.
- Quickly seeing how your relational design maps to Prisma's model syntax.
- Reducing transcription errors when converting many tables into Prisma models.
- Learning Prisma schema conventions by generating from a structure you already know.

FAQ
Will I need to edit the generated schema?
Usually a little. The generator gives you a strong starting point, but you may refine relation names, attributes, or types to match your intent.
Does it map relationships between tables?
Yes. Foreign-key style relationships are translated into Prisma relation fields where the structure makes them clear.
Can it run a real introspection against my live database?
No. For privacy it works from the structure you provide rather than connecting to your database directly.
Is my schema information private?
Yes. Generation happens in your browser, so your table and column details stay local.
Can I use Prisma Schema Generator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
