A Free dbdiagram Alternative

Like dbdiagram, VibeSchema is a DBML (Database Markup Language) based tool for creating database diagrams. VibeSchema is fully free and easy to use. It also scales very well to large schemas - for example, diagram views can be used to visualize large schemas in manageable parts.

It also has the other useful features you’d expect such as PNG/SVG exports, Auto-Layout, imports from other languages, and an AI assistant which can edit your dbml schema and answer questions.
