ESPEasy (development branch)
Introduction https://espeasy.readthedocs.io/en/latest/ (and, mostly outdated, wiki: https://www.letscontrolit.com/wiki/index.php/ESPEasy#Introduction)
MEGA This is the development branch of ESPEasy. All new features go into this branch, and it has become the current stable branch. If you want to do a bugfix, do it on this branch.
Check here to learn how to use this branch and help us improving ESPEasy: Starter guide for (local) development on ESPEasy
Web based flasher (experimental)
To make it easier to get started, one may flash a build directly to the ESP from your browser. Currently only Chrome and Edge are supported.
See this flash page to try the new web flash feature.
The web flasher is using ESP Web Tools made by the people behind ESPHome and Home Assistant.
Binary releases
On demand, controlled by the repo owner, our build-bot will build a new binary release: https://github.com/letscontrolit/ESPEasy/releases
The releases are named something like 'mega-20220626' (last number is the build date)
Depending on your needs, we release different types of files:
The name is built up from a few key parts:
ESPEasymega_[releasedate]_[build-type]_[opt-arduino-library]_[hardware-type]_[flash-size][filesystem-size]\[opt-build-features].bin

N.B. Starting with release 2023/12/25, All ESP32 LittleFS builds use IDF 5.1, to support newer ESP32 chips like ESP32-C2 and ESP32-C6 and SPI Ethernet. Other SPIFFS based ESP32 builds will be migrated to LittleFS as SPIFFS is no longer available in IDF 5 and later. A migration plan will be made available in 2024.
