For a bit more simple alternative I might suggest Fractal - https://fractal.build . While it doesn't have so much knobs and whistles as StorybookJS, it's easier to set up and get running for smaller projects.
Looks very interesting. The docs for it appear to be using VuePress.
So I checked it out and it’s not clear to me how if it all it supports different frameworks. All the examples seem to be for handlebars based components not actual components in the JS framework sense of the word.
