I found Harp.js pretty good for a general purpose static site gen. It's basically just a nice pre-configured jade/ejs/sass/less/coffeescript/browserify package.

I found Harp.js pretty good for a general purpose static site gen. It's basically just a nice pre-configured jade/ejs/sass/less/coffeescript/browserify package. As long as you follow the 'rules' in terms of project structure, it just works as both a server and a static renderer for the above. It can be as complex or simple as you like - you could use it for a blog even, you'd just need to write some of the logic yourself in your templates. I have used it personally for simple 2-3 page sites, where all I want to do is use some simple templates, compile some sass and bundle my scripts, without having to faff with config and build pipelines.
