Games whose interface came out of v0: menus, HUDs and shells generated fast so the maker could spend time on the actual mechanic.
Nobody has shipped a game here that credits v0. If you have one, adding the credit takes one checkbox at submission.
What people ask before they pick a tool, or before they trust a listing that credits one.
For the shell around a game (menus, HUDs, settings, leaderboards), it is fast. It will not write your game loop, and none of the makers here claim it did.
Makers pick their tools from a list when they submit, and that is what this page filters on. It is self-reported and nobody audits it, so treat it as a credit rather than a certificate. Where a game links its source, you can go and look.
No. v0 was used to build them, not to run them. Every game here is a link that opens in a normal browser tab, with nothing to install and no account to make.
The split varies enormously and the tag does not tell you which end of it a game sits at. Some people here architect everything themselves and hand over the tedious parts; others describe a mechanic and iterate in conversation until it plays well. It is a fact about the process, not a verdict on the result.
Every tool with a page here, with a live count of what has shipped on it. Most games credit two or three, so these lists overlap by design.
