FAQs ⁉️

Is dbdiagram.io free? Will I ever have to pay for it in the future?

Yes dbdiagram.io is free to use. We might introduce paid plans with more features in the future. But when we do, there will always be a free version that you can comfortably use for your need.

Who are you guys? And why did you guys build this?

We are Holistics.io, a Singapore-based BI product company. DBDiagram was born out of our internal feature to quickly visualize the database for our customers. We thought it was cool to turn that into a standalone product for the data community to use.

I'm using dbdiagram.io for my day-to-day professional work. Can I pay some subscription to get better features and support?

Thanks for the thought! As shared, we're looking into introducing paid plans down the road. But if you want to support us, you can
- Tweet about dbdiagram.io with your friends, or share on Facebook and LinkedIn.
- Check out Holistics.io, a simple yet powerful BI tool to turn your database data into insights
