"I am using Felgo Live code reloading and my feedback is.. WOW! It is SO much easier!! So fast! I've several devices connected at once and it's worked perfectly. This is already speeding up my development massively."
“Using Felgo as a front-end with simple off the shelf components, QML for custom visual components and the entirety of Qt and C++ as a back-end makes even the most difficult apps easy to build.”
"If I only new about Felgo before! It would have saved us about 50% of the development time compared to plain Qt, and we would have been able to focus on the app itself, instead of recreating problem solutions that are already provided by Felgo, and that are not unique or specific for our app. So, please: Don’t make the same mistakes, use Felgo! Just as we will, from now on."

Embedded Development with Felgo
The navigation paradigms on iOS and Android are different. On iOS you have a swipe-back gesture to navigate back in a navigation stack. On Android you usually use a navigation drawer that slides in from the left side. Felgo Apps abstracts these navigation differences and allows you to use just a single Navigation component, that works cross-platform.
Simulate Platform at Runtime
Speed up your development and testing time with the live platform simulation feature by Felgo: Simulate any platform and change it at runtime on your PC!
The native components and navigation automatically change their style to the new platform. This allows you to rapidly test how your app looks like on iOS and Android on your Desktop PC. The start time of your app goes from 1-2 minutes, down to just a few seconds!
Did you optimize your app for smartphone AND tablet already? This can be a tricky challenge, because with wider screens you can show more information in your app and make the user experience even better. If you optimize for smartphone only, you’re reducing your potential for success.
With Felgo, you don’t need to change your existing code but can use the same source code for phones & tablets. You get a “tablet view” with a navigation page on the left and the actual content page on the right automatically when the screen gets bigger.
Save 80% code and more!
Felgo allows you to save huge amounts of code, compared with pure Qt projects, or other frameworks and languages. This results in less maintenance effort, fewer errors and increased development speed.
Here are 2 quick case studies, to show you the potential code savings for your own applications.

Let's make something great together and join our satisfied customers:
Felgo can be used with both the open-source and the commercial Qt licenses.
Do I need a Qt commercial license for Felgo?
The Qt open-source license requires you to comply with LGPLv3. 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, even if your license is expires. Of course you will not be able to release new updates that include commercial Felgo features, without an active commercial license.
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 Personal license, but is not open-source as a whole. Commercial users of the Indie or 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?
