## What it is
ESPUI is an Arduino-style C++ library that serves a web-based user interface from ESP8266 and ESP32 microcontrollers using websockets. It lets you create and update UI controls like buttons, sliders, switches, and inputs from any browser without external servers or internet connectivity.

## Use cases
- build a web control panel for an ESP32 project
- control IoT devices from a phone or tablet browser
- add sliders and buttons to an ESP8266 without writing HTML
- create a captive portal interface for a microcontroller
- remotely monitor and adjust sensor values over WiFi
- make a simple dashboard for an Arduino ESP32 sketch

## When to choose
- you need a quick web UI on ESP8266/ESP32 with minimal boilerplate
- you want browser-based control without hosting a separate server
- you prefer simple Arduino-style syntax over writing frontend code

## When to avoid
- you need a complex, polished production web dashboard
- your project is not on ESP8266 or ESP32 hardware
- you need advanced charting or graphing features (still experimental)

## Facets
- artifact type: library
- maturity: active
- function: ui-components, websocket, http-server, gui
- domain: iot, web-development, embedded-systems, frontend
- platform: embedded, iot, cpp, browser
- tags: esp32, esp8266, arduino-library, websockets, captive-portal, spiffs, no-server-ui
