Lucidchart ERD Alternative: A Desktop ERD Tool That Connects to Your Database

Lucidchart ERD Alternative: A Desktop ERD Tool That Connects to Your Database

Short summary

Schemity is a $129 desktop ERD tool that connects directly to PostgreSQL, MySQL, SQL Server, and SQLite, reverse-engineering live schemas with foreign keys intact. Unlike Lucidchart, which requires manual CSV/TSV exports and file uploads, Schemity maintains a persistent database connection and stores diagrams as plain JSON files in Git. The post is written by Schemity's builder and functions as a product comparison and pitch.

  • •Schemity connects directly to databases; Lucidchart requires manual file exports
  • •Diagrams stored as JSON in Git; one-time $129 purchase vs per-seat SaaS pricing
  • •Author discloses he builds Schemity — post is a promotional comparison
