Vertabelo, now Redgate Data Modeler, suits teams that want a hosted modeller everyone can open in a browser, with shared models, version history and generated DDL. It is subscription only, logical modelling needs the Pro edition, and since the standalone reverse engineering tool was retired on 31 October 2026, bringing in an existing database means importing a SQL script.
Overview
Vertabelo Data Modeler was a browser-based database design tool from the company Vertabelo. Redgate Software bought it in September 2025 and launched it under the name Redgate Data Modeler in October 2025. Redgate says existing users keep their functionality and that it plans to add DevOps integration. The old Vertabelo brand now belongs to the separate LearnSQL.com and LearnPython.com business.
The product runs entirely in the browser with nothing to install; Redgate's requirements page recommends Chrome. You draw logical and physical models, validate them as you work, and export create, drop or change scripts for the target database. Redgate's requirements page lists PostgreSQL, MySQL, MariaDB, Oracle (11g to 21c), SQL Server (2012 to 2019), SQLite, IBM Db2 9.7, HSQLDB, Amazon Redshift, Google BigQuery and Snowflake.
Key features
- Physical models for ten database types, plus logical models in the Pro edition
