## What it is
Lopaka is a browser-based graphics editor for designing pixel-perfect UIs for embedded displays, with code generation for libraries like U8g2, TFT_eSPI, AdafruitGFX, LVGL, and Flipper Zero. It converts imported images, GIFs, and videos into formats such as 1-bit XBMP bitmaps or RGB565 arrays and exports ready-to-compile C/C++ source.

## Use cases
- design graphics for an Arduino TFT display and export C++ drawing code
- convert a PNG to an XBMP bitmap for a monochrome OLED
- create a Flipper Zero screen with live preview
- generate RGB565 image arrays for an ESP32 color TFT
- design an ESPHome display UI and wire it into YAML
- draw pixel-perfect icons and fonts for a Watchy e-ink watch
- import a GIF and generate frame animation playback code for a microcontroller

## When to choose
- you need to design graphics for embedded display libraries like U8g2, TFT_eSPI, or AdafruitGFX
- you want automatic conversion of images to bitmap formats your MCU display supports
- you prefer a visual editor over hand-coding draw calls for Arduino/ESP32/STM32 projects
- you want ready-to-compile source code generated from a canvas design

## When to avoid
- you need a full embedded GUI framework with runtime widgets and touch events rather than static graphics code
- you target platforms not among the supported display libraries
- you need native desktop tooling rather than a browser-based editor
- you require unlimited projects and assets without a paid plan
