DrawSQL

DrawSQL is a database schema and ER diagram tool that helps engineering teams design, visualize, and document database schemas in a shared workspace. It supports MySQL, PostgreSQL, SQL Server, and MariaDB, with a visual editor that handles column types, constraints, indexes, and foreign key relationships for each database driver. Teams use DrawSQL to design new schemas visually, import existing databases from SQL, and maintain a shared reference that the whole team can edit and keep current. DrawSQL AI reviews schemas for missing indexes and naming inconsistencies, generates multiple related tables from a single description, and is database-driver-aware — suggestions match the syntax and conventions of the selected database. **Key capabilities:** - **SQL import and export** — paste CREATE TABLE statements from any supported database and get an editable ER diagram in seconds. Export back to DDL, Laravel migrations, or JSON. - **Real-time multiplayer editing** — team members edit the same diagram simultaneously with live cursors and instant sync. Available on Team and Enterprise plans. - **Table groups** — organize related tables into named subject areas (Billing, Auth, Content) to keep large schemas readable. - **Version history** — every save creates a snapshot. Roll back to any previous version. - **Template gallery** — 200+ real-world database schema templates from open-source packages and production apps, including WordPress, Laravel, Shopify, Discourse, and Ghost. Fork any template as a starting point. DrawSQL is used by developers, tech leads, and database administrators at organizations ranging from startups to enterprises. Free plan available — no credit card required. Paid plans start at $19/mo for solo developers and $59/mo for teams with real-time collaboration, with enterprise pricing available for SSO, audit logs, and priority support.
