history
Project history and usage
ERAlchemy is a Python command-line and library tool for generating entity-relationship diagrams from live databases, SQLAlchemy models, or its own markdown-like ER representation.
Project history
The official repository was created in 2015 and published a 1.0.0 GitHub release later that year. Its README says the tool was inspired by BurntSushi's `erd`, but differs by rendering diagrams directly from databases rather than only from ER markup.
Adoption history
ERAlchemy's adoption is mostly in the Python database-tooling niche: the README emphasizes pip, conda-forge, SQLAlchemy URLs, Graphviz output, and command-line generation. Homebrew and Fedora packaging make it convenient outside Python-only workflows, but the project remains a focused documentation and schema-visualization utility rather than a broad platform.
How it is used
Common usage is `eralchemy -i DATABASE_URL -o diagram.pdf` or rendering from SQLAlchemy metadata in Python. The README also documents markdown input, Graphviz or PyGraphviz backends, Mermaid ER output, filtering tables or columns, and schema selection for PostgreSQL.
Why package nerds care
Package nerds care about ERAlchemy because it bridges Python packaging, system Graphviz dependencies, database drivers, and CLI ergonomics. It is a small example of why Homebrew-style formulas matter for Python tools that need native graph-rendering support.
Timeline
- 2015: The GitHub repository was created.
- 2015: Version 1.0.0 was published on GitHub releases.
- 2020s: The README documents Graphviz/PyGraphviz backends, conda-forge packaging, Mermaid ER output, and SQLAlchemy-based database URLs.
Related projects
- ERAlchemy is related to SQLAlchemy, Graphviz, PyGraphviz, Mermaid ER diagrams, and BurntSushi's `erd` markup-oriented diagram tool.
