Use Cases

See how developers, vibe coders, and teams use ER Flow to design better databases.

Design databases visually while your AI writes the code

Visual schema design with automatic Laravel migration generation

Let your AI coding assistant design your database

Let Windsurf design your database schema while you stay in flow

✓Windsurf's Cascade agent calls ER Flow's MCP tools autonomously, no prompting required per step
✓get-data-model-dbml gives Cascade full schema context before every change, preventing collisions
✓Batch operations let Cascade build entire domain schemas — users, billing, permissions — in one shot

Design your Supabase schema visually before you build

✓Full PostgreSQL support including column types, constraints, and sequences used by Supabase
✓Design join tables for many-to-many relationships that feed into Supabase Row Level Security policies
✓Model views that map directly to Supabase's auto-generated PostgREST API endpoints

Visualize and design your Prisma data model before writing schema.prisma

✓Visualize complex Prisma relations (one-to-many, many-to-many, self-referential) as a diagram before coding
✓Design composite indexes and unique constraints visually, then translate them directly to schema.prisma
✓SQL import reverse-engineers an existing database into a visual diagram when adopting Prisma on a legacy project

Plan your database before wiring up Server Actions and API routes

✓Design the full data model for Next.js apps — users, sessions, content, billing — before writing any ORM code
✓AI integration via MCP Server: describe a feature to Cursor or Windsurf and see the schema update live in ER Flow
✓Real-time collaboration so full-stack teams align on schema before splitting into frontend and backend tracks

Visualize your Django models before writing a single migration

✓Visualize Django model relationships — ForeignKey, OneToOneField, ManyToManyField — as a clean ER diagram
✓SQL import reverse-engineers any existing Django app's database into the visual canvas in seconds
✓Design junction tables for ManyToManyField with through= models and see the full relationship graph

Visual schema design that speaks Rails conventions

✓SQL import converts schema.rb output into a full visual ER diagram in seconds
✓Checkpoint-based diffing shows exactly what changed so you know what your next migration must contain
✓Design polymorphic association tables and STI structures visually to catch mistakes before code review

A professional-grade ER design tool with enterprise database support

✓Full multi-database support: PostgreSQL, MySQL, Oracle, SQL Server, and SQLite in a single tool
✓Stored procedures, triggers, and views are first-class objects on the ER canvas — not afterthoughts
✓Checkpoint-based versioning creates a complete audit trail of every schema decision and its rationale

Move fast without breaking your database

✓Visual schema that the whole team understands — engineers, product managers, and technical co-founders
✓AI integration via MCP Server lets a solo founder scaffold an entire MVP database by describing it in natural language
✓Real-time collaboration keeps distributed startup teams aligned on the data model without endless Slack threads
