I really like it. API-first git repos without the limitations of a git service like github that are built primarily for humans. Looks like a competitor to code.storage by pierre.

Zig is a great choice. I spent the last three years working on my own git implementation in Zig (see my profile) and it's really the perfect language for this. It gives precise low level control and heavily emphasizes eliminating dependencies (like libc) which makes it perfect for web assembly.
