Why it matters

Draws an ER diagram from a Prisma or Drizzle schema and generates the matching SQL DDL.

Prisma schema parser (models, enums, @relation, @@index, @@id, @default, native types) and a Drizzle TS subset parser (pgTable/mysqlTable calls, no eval); relation validation; DDL emitter per provider; reuses sql-ddl-erd's layout and renderer. Everything runs in your browser; nothing you paste is sent unless you press Fetch.

  2. Read the summary and the table or preview.

FAQ

Is my input uploaded?

No. The work runs in your browser and nothing you type, paste or upload is sent anywhere.

Will this change my site for me?

No. It shows results and, where it writes rules or files, you copy them and apply them yourself.

Can I rely on this as official guidance?

It follows public documentation and well-known algorithms, and tells you where it is a subset or a simulation. Confirm critical changes in the official tool or a staging environment.
