Instead of Felgo
Felgo alternatives
Felgo combines native cross-platform app, game and embedded development in a Qt-based SDK. QML and JavaScript are its main languages, with C++ supported, and Live reload updates connected devices after saves. Its 2D engine includes Box2D physics, particles, multitouch and animations. App projects can use cameras, sensors, files, WebSockets, Bluetooth LE and NFC. Cloud Builds work from a browser, while Game Network provides achievements, leaderboards, challenges, cloud storage and offline support. Targets include Android, iOS, Windows, macOS, Linux and web, alongside a visual UI designer, emulator and app packaging.

Dear PyGui
Free plan LinuxMacWindows
An alternative may fit better when Qt, Felgo’s licensing limits or subscription costs do not match your project. Personal and Startup licenses limit annual turnover below €50,000 and €100,000; Startup costs €79 a month billed annually per developer, and Business costs €245 a month billed annually. Compare app and embedded requirements with game-focused workflows, then weigh scripting choices, visual tools, source availability, multiplayer support, console exports and free-plan limits. Platform coverage also matters when choosing a replacement.
