ERAlchemy is a Python tool that generates Entity Relationship diagrams from databases or SQLAlchemy models, outputting images, PDFs, or markdown .er files. It works via a command-line interface and uses Graphviz for rendering.

Use cases

• generate an ER diagram from a postgres database
• visualize database schema as a pdf
• create entity relationship diagram from sqlalchemy models
• document database schema automatically
• export database schema to markdown er file
• exclude audit tables from schema diagram

When to choose

• you need ER diagrams from a live database or SQLAlchemy models
• you want CLI-based schema visualization with filtering of tables/columns
• you want output as PDF, image, or markdown

When to avoid

• you need interactive database diagramming tools with drag-and-drop editing
• you cannot install Graphviz dependencies
• you need diagrams for non-relational (NoSQL) databases
