Universal Schema Visualizer
Paste Prisma schemas, SQL DDL, or MongoDB JSON — get an interactive ER diagram with relationships, export PNG or JSON, and share a link.

Prisma schema visualizer for faster data modeling
A dedicated Prisma schema visualizer helps you readschema.prisma as a graph: models become nodes, relations become edges, and you can click any table-like shape for fields, types, and keys. Whether you are onboarding to a codebase or planning migrations, turning ORM source into an ER-style chart reduces cognitive load compared to scanning raw declarations alone.
SQL schema to diagram (PostgreSQL & MySQL DDL)
Turning SQL schema to diagram form is ideal when you inherit a legacy database or export DDL from tools like pg_dump. Paste CREATE TABLE scripts with primary keys and foreign keys; the parser extracts columns and draws relationships between tables. For many teams, this is the quickest sanity check before refactoring joins or documenting ownership between entities.
MongoDB schema visualizer from JSON Schema or samples
MongoDB does not enforce one static layout like SQL. This Mongo schema visualizer accepts Extended JSON Schema ($jsonSchema), BSON type hints, or representative documents: inferred fields appear on the canvas, and lightweight reference hints may appear when keys look like identifiers. Use it to align backend and frontend on embedded structures without assuming rigid foreign keys everywhere.
Privacy & performance
Parsing and layout run in your browser. Nothing is uploaded to TinkerTools servers for visualization. For large schemas, use search and fit-to-screen controls to stay oriented; export PNG or JSON when you need to attach a snapshot to a design doc or pull request.
