Does .git exist?
No. No — .git is not a TLD. It's the folder Git stores its data in, not a domain extension.
The full story
Every Git repository holds a hidden .git directory, so developers reach for .git as if it were a TLD. It has never been delegated to the root and ICANN holds no application for it. Building developer tooling? The endings below are real, resolvable, and carry the same engineer-friendly signal.
What to use instead
.dev — Best value in domains for anything developer-facing.io — The default startup TLD of the 2010s.sh — The shell-script TLD
Wondering about another extension? Every real TLD is in the directory.
