## What it is
GUIslice is a lightweight C GUI framework for embedded touchscreen TFT displays, supporting a drag & drop builder to generate layouts. It runs across Arduino, Raspberry Pi, ESP8266/ESP32, Teensy, STM32 and Linux via display drivers like Adafruit-GFX, TFT_eSPI, UTFT and SDL.

## Use cases
- build a touchscreen gui for an arduino tft display
- create embedded ui for esp32 with touchscreen
- design gui layouts with drag and drop for raspberry pi pitft
- add buttons and sliders to a tft lcd on m5stack
- run a touchscreen gui on linux with sdl
- make a control panel interface for teensy tft display

## When to choose
- you need a lightweight, no-dynamic-allocation GUI in C for microcontrollers
- you want one codebase across many displays, touch controllers and boards
- you prefer designing layouts visually with a drag & drop builder

## When to avoid
- you need a modern GPU-accelerated or vector-graphics UI (e.g. LVGL-style animations)
- your target is a desktop or web application rather than embedded hardware
- you require a rich widget toolkit beyond basic embedded controls
