What Customers are saying about Felgo

  • "If I only knew 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."
    Oliver Kuss
  • "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."
    Fayzan Ahmed
  • "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."
