FAQ

When do I need a commercial license?

If you are building a closed-source product, doing client work, or otherwise not using Doors under AGPL-3.0 terms, you need a commercial license.

How do I purchase a license?

Click the corresponding license card to learn more or start the purchase process. Alternatively, you can write an email to sales@doors.dev.

What counts as an app?

One app means one Doors-based product, internal system, or client project, regardless of how many servers, instances, regions, or domains it runs on.

What if I deploy separate copies for different customers?

If each customer gets their own deployment, each deployment counts as its own app.

Can I start under AGPL and move to commercial later?

Yes. If your project later needs a commercial license, you can switch.

What does lifetime mean?

A lifetime license covers the licensed app indefinitely, including future updates.

Is this page legally binding?

No. This page is a non-binding summary. Commercial licenses are issued through an Order Form and a separate commercial agreement.
