GEA vs LVGL

LVGL is a C graphics library for embedded displays, where the UI is built through its C API. LVGL Pro is a commercial toolkit on top of it, where you author the UI in XML through a visual editor. GEA compiles TypeScript and real CSS to native code. The table below lays all three out side by side.
