Azimutt is a database exploration and analysis platform that helps teams visualize, document and optimize database schemas and data. It provides a scalable ERD, a compact DSL for designing schemas (AML), connectors for many databases and tools for documenting and analyzing schema quality.

Key Features

  • Scalable interactive ERD viewer that lets you choose which tables/columns/relations to show and follow relations visually
  • AML (Azimutt Markup Language) for fast, text-first schema design and conversions to SQL dialects
  • Gateway architecture to connect to many databases via a Node.js gateway and a CLI for exports and analysis
  • Table/column notes, tags, layouts and memos for contextual documentation and shareable/embedable diagrams
  • Schema analysis and linter-style checks to surface inconsistencies and best-practice suggestions
  • Data navigation and on-demand data access (follow foreign keys, inspect entities) for deeper exploration
  • Integrations and developer tooling: CLI, VS Code extension, browser extension, Docker deployment and sample projects

Use Cases

  • Rapidly explore and document a large or legacy relational schema to onboard engineers or analysts
  • Prototype and design schemas using AML, then export or convert to target SQL dialects
  • Audit and analyze schema health to find inconsistencies, missing indexes or questionable relations

Azimutt combines visual exploration, structured documentation and automated analysis to make databases easier to understand and maintain for teams. It is geared toward developers, data engineers and architects who need a compact, shareable view of complex schemas.
