I have a ton of unfinished open source projects, but here's a recent small one I believe can take off:

https://github.com/mourner/tinyjam — a bare-bones, zero-configuration static site generator that deliberately has no features, an experiment in radical simplicity.

Essentially a tiny, elegant glue between EJS templates and Markdown with freeform structure (enabling incremental adoption) and convenient defaults, written in under 120 lines of JavaScript.

I also made a modern EJS implementation specifically for this: https://github.com/mourner/yeahjs And planning to implement a strict, minimal subset of YAML to switch over to: https://github.com/mourner/yeahml

Will be happy to hear any feedback :)
