ESPEasy is a long-running open-source firmware that turns an ESP8266 or ESP32 into a web-configurable node: wire up sensors and actuators, pick plugins in a web UI, and publish readings over MQTT/HTTP — without writing any code. Flashing runs over the Web Serial API, so it needs Chrome, Edge or Opera.
ESPEasy does not implement Improv-Serial, so after the install completes the board starts its own Wi-Fi access point (usually named ESP_Easy). Connect to that AP from your phone and enter your Wi-Fi details in ESPEasy's own captive portal.

ESPEasy doesn't support the in-browser Improv setup. After flashing, it opens its own Wi-Fi access point — join it from your phone and use ESPEasy's captive-portal page to enter your network details.
ESPEasy's classic target is the ESP8266 (Wemos D1, NodeMCU); the ESP32 build adds Bluetooth and more GPIO. The installer detects your exact chip and downloads the matching image.
