A database exploration tool for designing, browsing, documenting, and analyzing schemas that have grown too large for a conventional ERD.
Azimutt is a full stack database exploration tool aimed at the schemas real projects accumulate, big and messy, where a standard entity relationship diagram stops being readable. Its authors found that ERDs break down once a schema grows, that data catalogs focus on governance and lineage while missing relational knowledge, and that database clients offer autocompletion and table lists but no visual help.
The backend and admin interface are written in Elixir and Phoenix, while the editor is Elm. Schemas can be written in AML, the modeling language Azimutt uses for fast diagramming, and any public SQL file can be loaded straight from a link, which is how the project offers a badge that opens a repository's structure file in the app.
The tool splits its work into five jobs.
- Design: sketch a schema in AML instead of dragging boxes into place.
- Explore: search everywhere, display only the useful tables and columns, and follow relations.
- Query: navigate data, follow foreign keys, and drop the entities you land on into the diagram.
- Document: attach notes and tags to tables and columns, then save layouts and memos scoped to a feature or a team.
- Analyze: scan the whole database for inconsistencies and for best practices worth applying.
Self-hosting runs from the project's Docker image with a full install guide, and there are a Heroku template and a Kubernetes chart alongside it. Local development needs pnpm, Elm, elm-spa, Phoenix, Elixir, and PostgreSQL. It suits a team that inherited a database nobody fully understands.
