## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 2, release rhythm 35, longevity 100
- inputs: {"age_days": 3910, "days_push": 590, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
An asynchronous web server library for ESP8266 and ESP32 microcontrollers, supporting WebSocket, Server-Sent Events, and event-driven request handling. The project has moved to the ESP32Async organization and this repository is kept only as a pointer to the new location.

## Use cases
- serve a web dashboard from an esp32
- async http server on esp8266
- websocket server on esp32
- host a config page on a microcontroller
- rest api on esp32 firmware

## When to choose
- building Arduino/PlatformIO firmware for ESP32 or ESP8266 that needs a non-blocking web server
- you need WebSockets or SSE on constrained hardware

## When to avoid
- starting a new project - use the ESP32Async/ESPAsyncWebServer fork instead
- you need a web server on non-ESP hardware

## Facets
- artifact type: library
- maturity: maintenance
- function: http-server, websocket, web-framework
- domain: iot, embedded-systems, web-development
- platform: cpp, embedded, iot
- tags: esp32, esp8266, async, arduino, rp2040, moved-to-esp32async
