drawDB vs Hackolade Studio

drawDB is a browser-based database diagram editor for modeling schemas, importing existing definitions and exporting SQL. It supports Generic, MySQL, PostgreSQL, SQLite, MariaDB, Microsoft SQL Server and Oracle diagrams. Imports include drawDB JSON and DDB files, DBML, and SQL scripts for the listed database systems; exports include SQL, image and document formats, drawDB JSON, DBML, Mermaid and Markdown. The free plan is listed at free and includes local diagrams, SQL dialects, and import and export. In the open-source editor, diagrams and custom templates live in browser IndexedDB, tying them to that browser profile. The maker says it can also be self-hosted with Docker. Pro options add cloud storage and sync, public sharing, AI assistance and version history; team options include workspaces, roles, diagram permissions and live collaboration. The AI assistant can create or edit schema elements from prompts, while the MCP server provides read-only access for compatible coding tools to schemas in Pro cloud workspaces. Schema context is sent to the AI service when it operates on a diagram.

Hackolade Studio is a data modeling and schema design tool for relational and NoSQL databases, APIs, and data exchange formats. It supports conceptual, logical, and physical models using ER diagrams and hierarchical schema views, with the maker describing more than 45 physical targets. Studio can reverse-engineer supported sources and generate DDLs, schemas, validators, and documentation. It supports forward engineering and SQL export, with a broad list of supported databases including BigQuery, Cassandra, MongoDB, MySQL, Oracle, PostgreSQL, Snowflake, and SQL Server. It runs on Linux, macOS, Windows, and the web. The free Community edition limits each model to 50 objects and omits advanced forward and reverse engineering, Git, and Collibra integrations. Its 14-day evaluation includes unrestricted Professional and Workgroup features and requires no credit card. Workgroup adds Git-based collaboration and support. Its monthly subscription is €175 a month; annual billing is €1,750 a year.
