What is this?

An extremely fast static file server. It offers a wide variety of customization options - from error pages to logging format packed into a single statically-linked binary.

All options can be set either from the CLI or from a sabo.tabby.yaml config file. Personally, I use it to mirror sites and content to TOR and other networks. All it takes is sabo-tabby -f ./my_folder --port $PORT.
