## What it is
An Arduino library for ESP8266 and ESP32 that manages WiFi connections with a fallback web-based captive configuration portal. When saved credentials fail, the device starts an access point so users can configure WiFi settings through a browser.

## Use cases
- configure wifi credentials on an esp8266 without hardcoding them
- let users set up wifi on an esp32 device via a captive portal
- fallback access point when saved wifi network is unavailable
- add custom parameters to device provisioning portal
- onboard iot devices to home wifi networks

## When to choose
- building Arduino or PlatformIO firmware for ESP8266/ESP32 that needs user-configurable WiFi
- you want a captive portal provisioning flow out of the box
- you need custom config fields alongside WiFi setup

## When to avoid
- targeting non-Espressif microcontrollers
- you need provisioning over BLE or a cloud service instead of a local portal
- your project is not using the Arduino framework
