Introduction

Schemity is a powerful tool designed for software engineers to transform complex database schemas into understandable systems. By using Context Views, Schemity allows users to break down large databases into focused, readable projections, making it easier to design, reverse-engineer, and evolve schemas with confidence.

Key Features

• Context Views: Create focused, read-only projections from a single source of truth, allowing for multiple perspectives such as auth, billing, and analytics.
• Multi-layer Modeling: Organize your database with tabs for systems, schemas for structure, and views for use cases.
• Git-native: Store your ERD as a JSON file in your repository, enabling easy version control and collaboration.
• Migration Generation: Automatically generate SQL diffs by comparing your ERD to the live database, facilitating seamless schema evolution.
• Local-First Design: Operates offline with no cloud dependency, ensuring data transparency and ownership.

Use Cases

Schemity is ideal for software engineers and database architects who need to reason about complex systems. It is particularly beneficial for those working with MySQL, MariaDB, PostgreSQL, SQL Server, and Supabase databases.

Unique Selling Points

• Offline Capability: Unlike many ERD tools, Schemity works offline, making it suitable for secure environments.
• Lightweight and Fast: At just 9 MB, it is a native app that downloads quickly and operates without the need for additional installations.

Technical Details

Schemity supports macOS, Windows, and Linux platforms. It connects to databases through direct or SSH connections and can operate in ERD-only mode for schema design without live database connections.
