ER Flow for Startups

Move fast without breaking your database

Startups iterate relentlessly — and every pivot risks breaking the data model. ER Flow gives founding teams and early engineers a single visual source of truth for the database schema: easy enough for non-specialists to understand, powerful enough to generate production migrations. At $7.97 per user per month, it costs less than a team lunch while saving hours of reverse-engineering and schema confusion.

Benefits

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
Checkpoint versioning creates a historical record of every schema decision as the product evolves
SQL migration generation for every iteration so schema changes reach production cleanly from day one
Free tier available — paid Pro plan at $7.97/user/month scales affordably as the team grows

How It Works

1

Describe

Tell your AI coding assistant (Cursor, Windsurf) what you're building. ER Flow's MCP Server scaffolds the initial schema on the canvas.

2

Review

Walk through the visual diagram with your co-founder or technical advisor. Catch design issues before writing any code.

3

Iterate

As requirements change, update the schema visually. Add tables for new features, rename columns, restructure relationships.

4

Migrate

Save a checkpoint and generate SQL migrations for each sprint. Apply them to staging and production with confidence.

5

Onboard

Share the live diagram link with every new hire. New engineers understand the entire data model on day one.
