Flash your ESP32 from the browser. No Python required.
Visit ESP32 Flasher →The Problem
Getting started with ESP32-based devices means installing Python, finding the right esptool version, debugging driver issues, and running a command that differs across operating systems. For firmware like ESPHome and Tasmota, this is the main barrier to adoption.
The Solution
A single browser tab that handles the entire flash process — chip detection, binary upload, progress reporting — using the WebSerial API. No install, no Python, no CLI. Works on Chrome and Edge on any OS that supports WebSerial.
Flash ESP32 firmware directly from a browser tab using the WebSerial API. Supports ESPHome, Tasmota, WLED, MicroPython, and custom binaries.
