Full architecture diagramming vs. database-only
drawDB is a specialized tool for database schema design. Diagrams.so generates complete architecture diagrams across all infrastructure layers.
Overview
drawDB is a free, browser-based database diagram editor. It's designed specifically for designing and visualizing database schemas. ERDs, table relationships, and data models. It does one thing well but doesn't address broader architecture needs.
Why teams choose Diagrams.so
- Full architecture diagrams—not limited to database schemas
- AWS, Azure, GCP infrastructure components, not just DB tables
- Architecture warnings for infrastructure best practices
- AI-powered generation from natural language
- Community gallery of complete architecture patterns
- Import existing .drawio files for free on all plans
