Does .html exist?
No. No — .html is a file extension only. page.html is a file on a server, never a whole domain.
The full story
Nobody has applied for .html as a TLD. The confusion is understandable since URLs historically ended in .html, but that's a path suffix, not a domain ending.
What to use instead
.page — Underrated Google Registry gem — cheap, HTTPS-enforced, and reads as a natural word for single-purpose sites.site — The most generic word in domains.dev — Best value in domains for anything developer-facing
Wondering about another extension? Every real TLD is in the directory.
