> ESPConnect is a free, open-source data recovery and backup tool for Windows, macOS and Linux. Zero-installation web application that lets you explore, back up, and manage your ESP32… right from your browser. It has 2,169 GitHub stars and is released under the MIT license.

ESPConnect is a browser-based control center for ESP32- and ESP8266-class boards. It runs entirely inside a modern Chromium browser so you can inspect hardware details, manage SPIFFS, Fat, LittleFS files, back up flash, and deploy firmware without installing desktop software.
