I found BashWrite which is just a very simple static site generator written completely in bash as a single file script.

The only dependency is having an up-to-date sed command which most systems should have. I use Alpine Linux which comes with a minimal sed command so I had to download the full command through my package manager.

It’s simple, basic and had support for the majority of markdown formatting. There’s some limitations due to it being written in Bash only but I am personally okay with that.

I found it on this list of static site generators if you’re curious to see more options.
