if you're worried about this going away, why not use something like hugo. It's markdown, and there are dozens of places that will host for free. I host on Netlify (free). If they go away or start charging, I have many more options, and as it's hugo/markdown, there's no lock-in. You can do that on the command line (ultimately it's just a text editor and git).
