Best Qt for MCUs Alternatives ranked by AI · updated Aug 2026
Qt for MCUs is a lightweight embedded GUI framework for creating on-device interfaces on microcontrollers. It targets product teams that want Qt tooling and declarative UI development with low memory and graphics requirements.
Top 6 Qt for MCUs alternatives
Electric UI is a development framework for building desktop interfaces that communicate with embedded hardware. It is aimed at embedded developers who...
Pros
- Separates the user interface from constrained embedded hardware
- Supports live telemetry and control workflows for development and testing
- Can reduce firmware-side graphics and rendering requirements
Cons
- Less suitable than on-device GUI frameworks for standalone consumer products
- Smaller ecosystem than Qt, LVGL, or Slint
- May require a connected host computer during operation

LVGL
LVGL
LVGL is an open-source graphics library for embedded systems, especially microcontrollers and small displays. It provides widgets, layouts, input handling, and rendering...
Pros
- Free and permissively licensed for commercial embedded products
- Runs on a broad range of microcontrollers and display hardware
- Has a large community and extensive widget set
Cons
- More firmware and hardware integration work than Electric UI
- Visual design workflows are less integrated than Qt or TouchGFX
- Requires careful performance tuning on constrained targets
Free, open source under the MIT license
4
Slint
Slint
Slint is a declarative UI toolkit for embedded devices and desktop applications, with Rust, C++, and JavaScript integration. It is designed for...
Pros
- Declarative UI syntax is more modern than many traditional embedded toolkits
- Supports both embedded targets and desktop development
- Rust, C++, and JavaScript support broadens implementation choices
Cons
- Smaller ecosystem and hardware track record than Qt or LVGL
- Commercial licensing may be required for closed-source products
- Embedded rendering still requires target-specific integration
Free for open-source projects; commercial licensing available
5
TouchGFX
STMicroelectronics
TouchGFX is an embedded GUI framework and visual development environment for STM32 microcontrollers. It is intended for teams creating touch-enabled displays with...
Pros
- Strong integration with STM32 hardware and development tools
- Includes visual screen design and code-generation workflows
- Optimized for responsive graphics on supported STM32 devices
Cons
- Limited to the STM32 ecosystem compared with Electric UI
- Less useful for host-based engineering dashboards
- Visual workflow can tie projects closely to generated code
Free for STM32 microcontrollers
6
Embedded Wizard
TARA Systems
Embedded Wizard is a commercial GUI technology for creating high-performance interfaces on embedded devices. It targets product teams that need visual design...
Pros
- Supports production-grade on-device interfaces across multiple hardware classes
- Provides visual design tools and code generation
- Offers professional support and embedded platform integrations
Cons
- Commercial pricing is less accessible for hobbyists and small prototypes
- More tooling and licensing overhead than LVGL
- Requires an embedded rendering architecture rather than a host-only UI
