Database Designer

TL;DR

Natural language to schema design. Describe your application in plain English and get a production-ready PostgreSQL schema with indexes, constraints, partitioning hints, and migration SQL.

10-Second Pitch

• **NL to DDL conversion**
• **PostgreSQL-optimized output**
• **Automatic index and constraint generation**
• **Migration SQL with up/down scripts**

Setup Directions

1. Install: npm install -g database-designer

2. Run: db-design generate --description "your app description" --output ./migrations/

3. Edit generated schema if needed

4. Apply with: psql -f ./migrations/001_initial.sql

Example Prompt

```

Design a schema for a multi-tenant SaaS with teams, users, subscriptions, usage events, and per-tenant SSO. Include partitioning hints for time-series tables.

```

Verdict

Database Designer is a focused, specialized tool — not a general-purpose framework. If your stack aligns with Claude-Code, it slots in cleanly. The audit score (90) reflects genuine production readiness.

The bottom line: if Claude-Code is in your stack, this is worth a look. If not, skip it.
