Sounds like any static site generator supporting Markdown will do.
- Jekyll: the OG, but requires a ruby toolchain.
- Hugo: compiles to a single static binary, but you may have to get used to its (Go text/html) templating.
- Zola: also compiles to a single static binary, but uses Jinja-like templating.
- Gozer [^1]: my own, like Hugo, but 1000x simpler. I rolled my own because I wanted something that didn't move under me in the next 10 years and just because it was fun and easy enough to build.
