Uno Platform
Overview
Uno Platform is an open-source framework that enables developers to build cross-platform applications using C# and XAML from a single codebase. Established by Jérôme Laban, Uno Platform was initially developed by nventive, a company founded in 2008 to deliver innovative software solutions. Uno Platform allows developers to target a wide range of platforms, including iOS, Android, WebAssembly, macOS, Linux, and Windows. As of the latest updates, the platform has successfully raised around C$3.5 million in seed funding, reflecting its growing traction in enterprise markets.
Recent Developments
- August 2025: Uno Platform raised a C$3.5 million seed funding round co-led by AQC Capital and Desjardins Capital, which will support the expansion of its premium tooling tier and the development of new features like Hot Design, a utility that allows for real-time interface modifications in running applications.
- July 2025: The release of Uno Platform 6.1 introduced CommandBarFlyout, a new UI control for efficient command placement in application interfaces. It also included improvements to status bar APIs on mobile devices and advanced cookie handling in the WebAssembly runtime.
- May 2025: Uno Platform 6.0 was announced along with Uno Platform Studio, which provides enhanced development tooling such as Hot Reload and the design-to-code Figma plugin. This release also incorporated a unified Skia rendering engine, improving app performance.
- January 2025: As the platform shifted towards enterprise support, resources and documentation for onboarding were updated to reflect recent improvements, with community feedback highlighting the need for comprehensive guides.

Early History
The origins of Uno Platform date back to 2008 when founder Jérôme Laban launched nventive, a consulting agency aimed at leveraging emerging app technologies. The need for efficient cross-platform app development led to the creation of the Uno Platform in 2013. It was initially used internally to target iOS and Android without abandoning the C# and XAML expertise over at Microsoft’s Universal Windows Platform (UWP). By 2018, Uno Platform was open-sourced during Microsoft's Build conference, marking its transition from an in-house tool to a publicly available cross-platform solution.
Company Profile and Achievements
Uno Platform operates on the premise of creating a versatile toolkit that simplifies the development of applications across multiple platforms. Key achievements include:
- 2018: After years of development and internal testing, Uno Platform was open-sourced to the community, enhancing its accessibility and fostering a growing network of contributors.
- 2020: The introduction of WebAssembly support extended Uno Platform’s reach, allowing applications to run within web browsers with the same codebase used for mobile and desktop apps.
- 2023-2025: A shift towards enterprise solutions saw the integration of premium tools like Uno Platform Studio, increasing developer productivity with visual design and live-editing capabilities.
- Continued Growth: It has maintained an active community on GitHub, seeing over 103 million NuGet package downloads and substantial contributions from independent developers and enterprises.
Current Operations and Market Position
Currently, Uno Platform positions itself as a leading solution in cross-platform application development by leveraging a robust rendering engine—Skia—for improved performance. It supports integration with popular IDEs like Visual Studio, Rider, and VS Code. Uno Platform facilitates rapid prototyping with its out-of-the-box tools like Hot Reload and Design-to-Code, thereby shortening the feedback loop for developers. By maintaining a focus on cross-platform UI and non-UI API support, Uno Platform remains competitive against .NET's native offerings, MAUI, and Blazor, providing comprehensive solutions for enterprises looking to unify their app development processes across various environments.
Conclusion
Uno Platform is shaping the future of cross-platform application development with its innovative tooling and community-driven growth. It continues to attract both developers and investors by solving key challenges in the app development cycle, providing a streamlined, efficient platform for building applications that look and perform consistently across multiple environments. As it evolves, Uno Platform is expected to further enhance its tooling suite, embrace AI-driven development practices, and persist in extending .NET capabilities to a broader audience, shaping its own niche in the enterprise software market.
