I used to host my site on Neocities, and I still host SimpleCodeEditor and SimpleMarkdown on Neocities. I have always wanted to be able to manage my Neocities site from the command line. Because of this, I have decided to make some tools for Neocities.
So far, I have a tool to upload to Neocities, and a tool to delete a file from Neocities. Soon, I will have tools to allow you to use Jekyll on Neocities, and a tool to upload a whole folder to Neocities all at once. The tools are open source.
