Beautiful, Fast, Easy-to-build Embedded GUIs

An embedded GUI (Graphical User Interface) is a software interface that is designed for use on an embedded system, such as a microcontroller or a single-board computer. Embedded GUIs provides a graphical interface for interacting with the system and enables users to control and monitor the system through visual elements such as icons, buttons, sliders, and text fields.

MicroEJ Embedded GUI solution provides your customers with beautiful Look & Feel and high performance, on markets such as wearables, home appliances, smart home, medical, smart printers, and more generally speaking any kind of small electronic products.


Embedded GUI example

Take advantage of impeccable, ultra-fast in execution embedded GUIs that will guarantee your customers a great user experience.

Adding to the benefits of stunning graphics, rich animations and interactions, MicroEJ’s portability across different electronics allow you to leverage your design investment by re-using the same graphical widgets for your whole line of products and create a distinctive user experience.


Make your GUI Fast and Easy

Unlock your competitive edge thanks to professional tools and libraries that will greatly facilitate your embedded GUI design and development for a product ready to launch in record time.

Thanks to MicroEJ’s simulation technology, quickly prototype your embedded GUI on virtual devices with fast-cycles iterations and get more regular feedback from your project stakeholders (designers, beta customers, marketing, etc.).

Control Your Costs

MicroEJ’s low-power Embedded GUI solution reduces your electronics costs by optimizing memory (RAM/ROM) and hardware resource usage.

Thanks to our technology, you won’t need a high-performance processor to achieve best in class UI: MicroEJ UI Engine requires a very small memory footprint and can be executed by simple and low-cost processors starting from 1$ price point (microcontollers/microprocessors).

Powerful Tools for Fast UI Prototyping

Simulate Your Product on a Virtual Device

Create your future future product without your hardware in hand: test several possible hardware configuration, evaluate the best compromise between features and electronic costs, interact with different teams to define the right specifications and simulate your system inputs/outputs such as sensors or actuators.


… And Execute on a Real Electronic Device

Developing for a real electronic board is as easy as for a virtual device. In fact, 100% of the code you might have created for your virtual prototype is directly portable without modifications, including the testing tools. Or, of course, you may choose to get directly to the subject and get your hands dirty on a real board, your choice!

Embedded GUI Libraries and Tools

Professional Tools and Libraries

Our easy-to-use APIs and comprehensive set of free GUI libraries and widgets (MicroUI and MWT) are our secret sauce for efficient cross-hardware development.

Fonts from all major font formats (including Latin, Arabic and Asian) can be imported, edited or designed from scratch thanks to our Font Designer & Generator.

Java/Android developers will love our intuitive tools for coding, testing (manual or automatic), debugging/profiling and internationalizing full-featured embedded GUIs.
