WorksCove ERD
Seoul, South Korea
What it is
WorksCove ERD is a web application for turning database structures into editable entity-relationship diagrams and exporting designs as SQL. It can reverse-engineer MySQL, MariaDB, PostgreSQL, Oracle, and SQL Server databases. Designs can be converted to SQL for MySQL, PostgreSQL, Oracle, or SQL Server, with data types and constraints mapped to the selected dialect. More than 20 validation rules check issues such as naming violations, circular references, and missing indexes. The service compares schema versions and creates migration scripts for differences. It produces table specifications in XLSX, Markdown, and HTML, plus ERD files in PNG and SVG. An AI assistant provides design and optimization recommendations. Team plans add real-time editing, invitations, seat management, and project permissions. Projects can use password-protected sharing with expiry and access-count limits. The Free plan allows three projects and 40 tables per project, with watermarks on PNG exports. Professional costs $10 a month; Team costs $20 a month.
