Felgo can be used with both the open-source and the commercial Qt licenses.

Do I need a Qt commercial license for Felgo?

No. The Qt open-source license requires you to comply with LGPLv3, but this does not mean that you need to share your own source code.

If I use the Qt open-source license, do I need to make my project open-source?

Felgo adds components, tooling and services on top of the Qt core. The Qt core itself is unmodified and you will be able to use your existing code together with Felgo.

I have existing Qt code, can I migrate and re-use it with Felgo?

Your published apps will stay fully functional, also after your license expires. You will not be able to release new updates that include commercial Felgo features, after your license expires.

What happens to my published apps, if my Felgo commercial license expires?

If you have questions about our licenses or billing, please get in touch with us by Email.

My question is not answered here. What can I do?

Felgo offers a free license for Personal use. Commercial users of the Enterprise license can obtain access to the source code, based on individual agreements. Demos and examples provided by Felgo are open-source.

Is Felgo open-source?

Felgo plugins can also be integrated into Qt projects that do not use any Felgo components. You can contact us to get more info.

Can I use Felgo plugins for monetization, analytics and more in my Qt app?
