Origin

This project was originally written by Melissa LeBlanc-Williams. Nabu Casa ported the code over to TypeScript and in March 2022 took over maintenance from Adafruit. In July 2022, the Nabucasa stopped maintaining the project in favor of an official, but very early release of Espressif's esptool-js. Due to the instability of the tool, Adafruit updated their fork with Nabucasa's changes in November 2022 and took over maintenance once again.

A live copy of the tool is hosted here: https://adafruit.github.io/Adafruit_WebSerial_ESPTool/
