How does this work?

ESP Web Tools uses the WebSerial API to talk to your stick over USB and upload the firmware binary. Nothing leaves your browser — there is no server in the loop. The binaries served from this page are the artefacts published in the GitHub Releases.

Browser support

Chrome 89+, Edge 89+, Opera. Not supported on Firefox or Safari yet. iOS / iPadOS cannot flash because WebSerial is not available there.

Trouble?

Make sure the USB cable is a data cable, not charge-only.
If no port appears, install the ESP32-S3 USB-JTAG/CDC driver (Windows).
If the flash fails mid-way, hold the BOOT button while clicking Install.
