Frequently asked questions
How do I generate an ERD from Prisma without installing a generator?
Paste your schema.prisma models into the box, no CLI, no generator block, no database connection. Models render as tables, scalar fields as columns, and @relation attributes as foreign-key lines, all in your browser.
Is it free?
Yes, completely free with no signup. Paste any size schema.prisma and explore the diagram instantly.
Is my schema uploaded anywhere?
No. Parsing and rendering run entirely in your browser with zero dependencies. Your schema is never uploaded, stored, or logged.
Which Prisma features are supported?
Model blocks with scalar, enum, optional, and list fields; @id, @unique, @default, @map, and @relation(fields, references); @@id, @@unique, and @@map table mappings. Relation-only fields render as edges, not columns, exactly like the database sees them.
Can I get SQL or a fuller diagram from this?
Yes. Copy as SQL exports the equivalent PostgreSQL DDL, and Open in dbdiagramr loads it into the full visualizer with search, export, and health analysis.
