Hackolade Studio
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.
