From Complex Code to Effortless Visual Creation

No-Code Development Tool for Embedded GUI Creation | Flint

Developing GUIs for embedded systems has long been a battle fought with lines of code. The process is slow, disconnected from the design vision, and requires highly specialized engineers, leading to frustrating iteration cycles and compromised user experiences.

Flint is the paradigm shift you've been waiting for. Our powerful no-code development tool replaces the need for manual coding with an intuitive, visual, drag-and-drop environment. Built from the ground up by embedded experts, Flint understands the unique constraints of your hardware—from memory-sensitive MCUs to powerful MPUs. Trusted by global OEMs and Tier 1s in Automotive, Industrial, and Medical domains, Flint is the definitive tool for realizing your GUI vision, faster and more efficiently than ever before.

Design Faster. Deploy Smarter.

Figma-to-Flint Plugin


Streamlined Design-to-UI Workflow for Embedded Interfaces

The Figma-to-Flint Plugin brings a faster, smarter, and more accurate way to move from UI design to embedded development. With a single click, your Figma layouts, layers, and assets can be exported directly into Flint—fully structured and ready for project integration. No more redrawing screens, slicing images, or manually rebuilding layouts.

This plugin helps teams reduce repetitive work, avoid mismatches between design and implementation, and accelerate UI delivery for embedded products.

Breathe New Life into Legacy Systems: Embedded GUI Modernization

Is Your Embedded GUI Stuck in the Past?

Many powerful embedded products are held back by dated, inefficient, and hard-to-maintain graphical interfaces. The cost and risk of complete software rewriting often seem prohibitive.

This is where Sparklet's rich experience shines. Flint is not just for new products; it’s a powerful tool for GUI modernization. Our unique architecture allows you to decouple the UI layer from the core application logic. This means you can design and deploy a modern, feature-rich frontend using Flint while preserving your existing, stable backend code.

Benefits of Modernization with Flint:

Drastically reduces the risk and cost compared to a full rewrite.

Introduce touch, gestures, and animations to legacy products.

Improve usability and customer satisfaction with a modern UX.

Extend the life and value of your proven hardware and software.
