What Felgo does
Felgo is a private, Vienna-based software company that builds a native cross-platform application development SDK layered on top of the Qt framework. Founded in 2012 (previously operating as V-Play before rebranding), the company provides a single-codebase toolchain that compiles QML- and C++-based applications natively to iOS, Android, Windows, macOS, Linux, Web (WebAssembly), and Embedded targets. The SDK includes 200+ APIs and components, a custom C++/OpenGL ES/Vulkan/Metal scene graph renderer, a QML Hot Reload engine, Cloud Builds CI/CD, a Cloud IDE, and a catalog of native plugins for third-party services including Firebase, AdMob, Chartboost, Soomla, Wikitude AR, OneSignal, and OAuth 2.0.
Felgo offers four product lines built on the same SDK: Felgo Apps (mobile and desktop), Felgo Games (game engine), Felgo Embedded (IoT/embedded targets), and Felgo Cloud tooling. The company monetizes through (1) quote-based SDK Business Licenses sold on annual or multi-year terms with bundled plugins and priority support, (2) professional services including custom application development, Qt consulting, Qt trainings and workshops, and Qt 6 porting/migration, and (3) a free 30-day business evaluation that includes onboarding, up to five hours of professional services, and a private Slack channel.
Felgo operates as an official Qt Technology Partner and Qt Service Partner (the highest tier of Qt Company affiliation). Go-to-market is hybrid: product-led growth via the free SDK download, Cloud IDE, and Cloud Builds self-serve funnels; enterprise field sales for Business licenses and large professional services engagements; and event-driven presence at Qt World Summit, Qt Day Austria & CEE, ESE Kongress, and Embedded World. Named enterprise customers include Telenav (navigation/telematics), Sioux Technologies (engineering), and UpdatePromise (automotive), and Felgo reports 100,000+ developers using the SDK across automotive, entertainment, manufacturing, and telecommunications verticals.

Felgo competitors and assessment
Company assessmentDirect peers
- Flutter: Google-backed cross-platform UI toolkit for iOS, Android, web, and desktop from a single Dart codebase. Most direct competitor to Felgo's value proposition in mobile cross-platform, with vastly larger developer ecosystem and tooling investment.
- React Native: Meta-maintained cross-platform mobile framework using JavaScript/React. Directly comparable to Felgo for cross-platform mobile and desktop app development, with Felgo explicitly positioning against React Native on code volume and performance.
- .NET MAUI (Xamarin): Microsoft's evolution of Xamarin for cross-platform native apps across iOS, Android, Windows, and macOS from C#/.NET. Direct comparator for enterprise cross-platform development with comparable single-codebase promise.
- Ionic: Cross-platform hybrid app framework using web technologies (Angular/React/Vue) plus Capacitor for native deployment. Targets similar SMB and enterprise developers who want cross-platform reach, though with a WebView-based approach rather than Felgo's native renderer.
- NativeScript: Open-source framework for building native mobile and desktop apps with JavaScript, Angular, or Vue; competes in the same niche as Felgo for cross-platform native development.
Broad incumbents
- The Qt Company: The vendor of the underlying Qt framework Felgo extends. As an upstream partner (not competitor for the same niche), Qt Company offers Qt Commercial licensing, Qt Creator IDE, and broader enterprise solutions overlapping Felgo's professional services scope.
- Unity: Dominant cross-platform game engine — directly comparable to Felgo Games for cross-platform 2D/3D game development, with far larger scale, ecosystem, and enterprise reach.
- Telerik (Progress Software): Established vendor of cross-platform UI components (Telerik UI) and developer tooling within Progress Software's broader portfolio. Comparable as an incumbent cross-platform UI toolkit vendor with similar IDE and component positioning.
Others
- Codemagic: CI/CD service purpose-built for mobile app builds, paralleling Felgo Cloud Builds. Comparable as mobile-app build/deploy infrastructure for cross-platform teams.
Emerging players
- Solar2D (Corona SDK): Open-source 2D cross-platform game engine using Lua. Comparable to Felgo Games in the indie/2D mobile game developer segment with a smaller, niche community.
