Before you choose
Compare free access and paid terms
Check whether a tool offers a free plan, a free trial or a paid plan. Pricing notes use different currencies, billing periods and units, so read the term beside the starting price.
A free plan can help you evaluate a workflow before committing to a paid option. A trial can provide time-limited access instead.
Match the platform to your setup
The list includes tools that run on Windows, Linux, macOS or the web. Other options are self-hosted or exposed through an API.
Choose a delivery method that fits where you work and how you need to connect the software to other systems.
Check reverse and forward engineering
Reverse engineering can help you work from an existing database structure. Forward engineering can help you turn a model into database structures.
Review the reverse-engineering and forward-engineering fields for the workflow you need before choosing a tool.
Review engines, deployment and file output
Compare the database engines a tool supports and the deployment methods it offers. Version history can matter when you need to review model changes over time.
Check export formats before you commit to a workflow, especially when another tool or service must read the model.
