draw.io vs drawDB

draw.io (also known as diagrams.net) is a free diagramming application used for flowcharts, network diagrams, wireframes, and technical documentation, with a strong emphasis on privacy and self-managed data storage. It is available as a browser app at app.diagrams.net and as a desktop application, and it deliberately maintains long-term backward compatibility with older diagram files.

drawDB is a web‑based tool that lets developers and DBAs create, edit, and share entity‑relationship diagrams directly in the browser. It supports forward and reverse engineering, letting you generate SQL from diagrams or import existing schemas. The platform is free, open‑source, and integrates with common version‑control workflows, making it ideal for collaborative schema design and documentation across teams.
