If you want to learn more about Vite, I recommend that you join Vite Land (https://chat.vitejs.dev). There is a very active and helpful community, and there are tons of opportunities to collaborate in the creation of plugins, integrations, and to improve Vite itself.

Thanks for the kind words! So awesome that you are sharing the tools with others, I hope the rest of the team liked it too :)

It is so cool to see the tool in the front page of HN! We got an article published in css-tricks on Thursday about why we think generators are good tools for learning https://css-tricks.com/layoutit-grid-learning-css-grid-visua...

We open-sourced Layoutit Grid just a few weeks ago. There is still a lot of features we would like to add to showcase even more how powerful CSS Grid is. In case someone wants to help us out! https://github.com/Leniolabs/layoutit-grid

I know it goes against the merits of the site, but it would be great if there was a fallback option to output CSS for browsers that do not support grids.

This would be pretty difficult, since at least some of the concepts of Grid (namely, anything involving calculation or auto-placement) are simply not supportable in old browsers.
