Theres experimental support for HTML export:

I tried this out about 6 or so months ago; it was pretty bad unfortunately. I was willing to put my money where my mouth is and pay a bit to dedicate resources for it like a bounty, but typst organisation doesn't seem to have something like that. I have actually donated to the project AND paid for a subscription to their web service though.
