How to better use your time - our productivity tips for Qt developers
How Felgo enables excellence developing apps with Qt - aim high!
For an application to comply with modern UX guidelines, it needs to provide an optimized experience based on the target platform and input method. It should adapt the information shown (“adaptive layouts”) based on the available screen size. It is the details that determine if an application is just ok and usable, or outstanding. Outstanding products are what we should aim for!
"We wanted to make a really good product - no compromises on quality due to time constraints. This is why we went for a supplier like Felgo. It was just a seamless way of working together."
"We use Felgo because of the integrated plugins, the live code reloading and the nice looking native components. It just saves so much time & makes my life easy!"
"I really had a good feeling about the team already just from working with the Felgo SDK. The working relationship was easy, excellent results, great team.
Felgo really stepped up to the plate and honored my faith."
Create iOS and Android apps with native look and feel, with 100% shared code base.
Accelerate your development speed with live code reloading.
Stop Waiting for Build, Package and Deployment Steps
With Felgo for WebAssembly, you get an improved version of the Qt WASM port, with several fixes and additional features. This allows you to put production-ready Felgo and Qt apps to the web, from your existing code-base.
You can also use QML Hot Reload to develop for WebAssembly.!
Automate your workflows to save precious time.
No need to reinvent the wheel. Integrate third party services and platform-specific functionality into your applications.
The Qt-friendly cross-platform backend solution.
The future is now. Add augmented reality or machine learning powered by Felgo APIs.
Create high performance embedded system apps & second screen apps. Native performance and rapid UI creation, powered by C++ & JavaScript. Learn more about embedded development with Felgo on this dedicated page.
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.
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.
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.

Felgo can be used with both the open-source and the commercial Qt licenses.
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.
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.
Felgo plugins can also be integrated into Qt projects that do not use any Felgo components. You can contact us to get more info.
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.
Felgo offers a free license for Personal use. Commercial users of the Business license can obtain access to the source code, based on individual agreements. Demos and examples provided by Felgo are open-source.
If you have questions about our licenses or billing, please get in touch with us by Email.
