dbdiagram.io vs dbdiagramr vs DrawSQL: 정직한 비교

The short version

dbdiagram.io is the original — great for writing schemas in code (DBML), but no live database connection. DrawSQL is a paid GUI tool with good auto-generation but requires a desktop app. dbdiagramr is free, runs in the browser, connects directly to Supabase/Neon/Railway, and generates diagrams from your live database in seconds.

Which one should you use?

If you… Use… Want to diagram an existing Supabase/Neon database dbdiagramr Want to design a schema from scratch in code dbdiagram.io Need a desktop GUI with export options DrawSQL Want free, unlimited diagrams dbdiagramr Need team collaboration dbdiagram.io or DrawSQL Want AI context for your schema dbdiagramr Are on a tight budget dbdiagramr

The real question

The tools aren’t competitors — they serve different workflows:

• Design first (dbdiagram.io): You write DBML, generate migrations, deploy to production.
• Existing database (dbdiagramr): You already have a database, you want to see what it looks like.
• GUI exploration (DrawSQL): You want a desktop app to browse, query, and export your schema.

Most developers use dbdiagramr to understand what they have, then dbdiagram.io if they want to redesign it.

FAQ

Can I import a dbdiagram.io diagram into dbdiagramr?

Not directly. dbdiagram.io uses DBML format. dbdiagramr connects to live databases. You’d need to deploy your DBML schema to a database first, then connect dbdiagramr to it.

Does dbdiagramr support MySQL?

Not yet. Currently supports PostgreSQL only. MySQL support is planned.

Is DrawSQL worth the money?

If you need a desktop GUI with export options and team collaboration, yes. If you just need to see your schema, dbdiagramr does it for free in the browser.

Can I use dbdiagramr with Prisma?

Yes. Prisma connects to PostgreSQL. Use your Prisma connection string (with ?pgbouncer=true if using Supabase pooler) and dbdiagramr will diagram your entire schema.
