With MicroEJ, you can rapidly design, test, and validate stunning UIs for cost-constrained embedded devices. Our unique software containerization and simulation capabilities, as well as extensive GUI libraries, widgets and tools, allow you to create premium experiences on MCUs and MPUs, reducing time-to-market and hardware costs.

See Your GUI in Action Within Days!

• Vector graphics and fonts, pixel-perfect animations & smooth transitions
• Optimized for low-power, low-cost hardware
• Design once, deploy on any platform
• Develop & test without hardware using Virtual Devices

Premium-Looking Embedded GUI on Cost-Effective Hardware

Smooth, responsive, and rich user interfaces—even on ultra-low-power devices.

• Crisp vector or raster graphics and smooth animations with ultra-low resource consumption
• Fast refresh rates and seamless transitions for a smooth user experience
• Customizable and extensible widgets to exactly convey your branding

Design & Test Your Embedded GUI Without Hardware Using Simulation

Reduce development time by 50% with virtual prototyping, before the hardware is even ready.

• Faster Iteration: Develop your user interface on a virtual device (exact copy of real technological environment) and get feedback in real-time.
• Stakeholder Alignment: Enable designers, product managers, and engineers to test and validate UI/UX before committing to hardware.
• Optimize Costs: Fine-tune processor and memory selection by simulating UI performance on various architectures.

Develop Once, Deploy Everywhere

Control your branding assets and scale your product line effortlessly, from entry-level to high-end devices!

• No need to rework the UI for different processors—design once, deploy anywhere.
• Supports MCUs & MPUs from leading manufacturers (NXP, Qualcomm, STMicroelectronics, Renesas, etc.), as well as any RTOS/OS (Zephyr Project, FreeRTOS, Linux, and more).

Real-World Performance Without the Complexity

Run advanced user interfaces on low-cost embedded processors.

• MicroEJ delivers 60 FPS animations with as little as 128 KB RAM—unmatched in embedded GUI frameworks
• Boots in under 25ms for an instant-on experience.
• High Efficiency: use available hardware accelerators for optimal efficiency and performance
• Low power consumption: ideal for battery-powered devices like wearables and IoT

Code Faster and Automate GUI Testing

Leverage mobile UI developers to create your GUI in no time!

• Multi-Language framework: create or reuse UI elements written in C/C++/Java/JavaScript/Rust or Kotlin
• Use your favorite IDE: MICROEJ SDK is compatible with IntellIJ IDEA, Android Studio, Eclipse, or Visual Studio
• Extensive quality insurance tools: test and enhance your GUI thanks to MicroEJ’s extensive QA tools, including automated testing tools (see overview)
