I like the idea of Super Simple Server, but I cannot have any proprietary software in my tech stack. If I am unable to maintain it myself if something goes wrong, then I cannot use it without introducing a potential liability. I am fine with any open source license whether it is apache-2.0 or GPLv3, I just cannot use proprietary software, especially for hidden services. I will just stick with lighttpd in the meantime.

All the best,

That point is correct. We need to be able to see thru every layer of the stack to fully service it. Especially in a high-security setting.
