Everything you need for embedded UI

Visual editor purpose-built for LVGL on microcontrollers.

Visual Editor

Drag-and-drop canvas with rulers, grid snapping, layers panel, and real-time property editing.

Clean C Code

Generate readable, modern LVGL C code. No runtime, no abstraction layer — just clean C you can inspect and modify.

Multi-platform

Export for ESP32, STM32, Arduino, Linux, or any platform with LVGL support. One design, many targets.

30+ Widgets

Button, label, slider, switch, chart, table, keyboard, dropdown, arc, spinner, and more — all configurable.

Style & Themes

Full style editor: colors, borders, shadows, opacity, gradients. Shared styles for consistent theming.

Flexible Export

Export as C files, ZIP archive, or PlatformIO project. Integrate with your existing build system.

Design visually

Drag widgets from the palette onto the canvas. Resize, position, and style each element with real-time preview. Layers panel for complex hierarchies.
