Fantastic project, love it! You have an amazing selection of supported protocols on the "wire side".
I'm the co-author and project lead of SSH-Stamp:
https://github.com/brainstorm/ssh-stamp
Our focus has been on the "network side" by running a SSH server instead of a Web Server and multiplexing protocols via SSH sessions.
Our project is admittedly not as mature as the ESP32 Bit Pirate but OTOH we run with Rust Embedded and support other targets than Espressif (currently experimental on RPI Pico2 and Sipeed BL616).
We need testers :D
