ER Flow for Next.js Developers

Plan your database before wiring up Server Actions and API routes

Next.js apps grow fast — and so do their databases. ER Flow gives Next.js developers a visual space to design their data layer before writing a single query. Whether you're using Prisma, Drizzle, or raw SQL with Supabase, ER Flow helps you get the schema right from the start so your Server Actions and API routes just work.

Benefits

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
PostgreSQL, MySQL, and SQLite support covers every hosting option from Vercel Postgres to PlanetScale
SQL migration generation means schema changes reach your database cleanly without manual ALTER TABLE statements
Checkpoint versioning tracks every schema iteration across a fast-moving Next.js project lifecycle

How It Works

1

Model

Create your data model in ER Flow: users, posts, comments, sessions — whatever your Next.js app needs.

2

Collaborate

Share the diagram with your team. Designers, backend engineers, and frontend developers review the schema together.

3

Iterate

Add feature tables as requirements evolve. Use AI via MCP to scaffold new domains from a plain-English description.

4

Generate

Create a checkpoint and generate SQL migrations for your target database — PostgreSQL, MySQL, or SQLite.

5

Integrate

Apply migrations, update your Prisma or Drizzle schema file, and wire up your Next.js Server Actions.
