For many years, the AVRDUDE source resided in public repositories on
savannah.nongnu.org,
where it continued to be enhanced and ported to other systems. In
addition to FreeBSD, AVRDUDE now runs on Linux and Windows. The
developers behind the porting effort primarily were Ted Roth, Eric
Weddington, and Joerg Wunsch.
In 2022, the project moved to Github (@url{https://github.com/avrdudes/avrdude/}).
