Quote from the homepage: Electrobun aims to be a complete solution-in-a-box for building, updating, and shipping ultra fast, tiny, and cross-platform desktop applications written in Typescript.

Ok, TBF they write "aims to be" and not "is", but still I think most people will get the impression that it's already cross platform and maybe some other stuff ist missing. So it would be more honest to also mention that it's currently MacOS only...

I think the actual website is pretty clear that the project is in the very early stages; I think the HN submitter (not the project author) made the headline sound more like this project is ready (perhaps inadvertently).

For me that first sentence made it obvious that this project isn't complete, but maybe a prominent "Preview release: Mac-only for now" would help some people.

"aims to be" is pretty ambiguous wording. It'd be clearer with a "aims to one day be..."
