How to choose

Which platforms does it need to run on?

Choose a tool that matches your working environment. Options in this list span Windows, Linux, macOS, browsers, self-hosted environments, and API access.

A web option runs in a browser, while self-hosted deployment keeps the service in your environment. Confirm the platform mark before paying.

Is there a free plan or trial?

Start with a free plan when you need to map a small project or compare workflows without an upfront charge. A free trial can help you assess paid features before subscribing.

For example, ChartDB offers a free plan and paid options starting at $25 per user monthly; dbdiagram.io has a free plan and a 7-day trial.

Does it support reverse and forward engineering?

Check both engineering fields for your workflow. Reverse engineering turns an existing database into a model, while forward engineering uses a model to create database structures.

A tool that lacks the direction you need can add manual work, so compare these marks with your starting point.

Which database engines and export formats does it support?

Match the database engines and export formats to the systems you already use. These fields show whether a model can move into your chosen database and file workflow.

Review the listed formats before selecting a tool for handoff, migration, or documentation.

How should deployment and version history affect the choice?

Use the Deployment and Version history fields to check how a tool fits release work and design changes over time.

If several people will review models or you need to revisit earlier designs, favor the workflow marks that match those needs.

Questions
