Azimutt

Azimutt is a modern database schema explorer and entity-relationship diagram (ERD) tool. It handles large, real-world schemas with hundreds of tables without becoming slow or unreadable — a key differentiator from traditional ERD tools.

Features

Schema Exploration

• Connect directly to your database (PostgreSQL, MySQL, MongoDB, SQL Server, and more)
• Auto-discover tables, columns, types, and foreign key relationships
• Navigate large schemas with search and column-level filtering
• Explore relationships by following foreign keys interactively

Diagram Editor

• Start from a full schema and hide tables to focus on what matters
• Group tables into named layouts (e.g. "auth", "billing", "core")
• Save multiple layout views for different parts of the schema
• Share diagram URLs with teammates

Data Analysis

• Column-level statistics and cardinality hints
• Identify missing indexes and nullable foreign keys
• Find orphan tables and unused columns
• Track schema changes over time

Integrations

• Connect via database URL or import from SQL DDL files
• Supports Prisma schema files
• REST API for CI/CD integration
