About
A home for games and worlds built with AI.
Velven is the community marketplace for spaces built with AI. Publish a space and Velven hosts it, or link one where it already runs. Velven is where they get found, entered, ranked, understood.
What counts as a space
Anything interactive in a browser you can enter or explore. Games, worlds, tools, wonders. If it needs a download or an install, it is not a space.
How ranking works
A play is counted when someone enters a space on its Velven page, or when the Velven badge on the creator's own site is viewed. One play per visitor per space per day. The creator's own plays on Velven never count.
Each signed-in person can like a space once and take the like back at any time.
- Plays today
- Plays in the last 24 hours. The default, so a new visitor sees what is being played now.
- Newest
- The most recently launched first.
- Creators you follow
- Only spaces by creators you follow, when you are signed in.
Publishing and linking
Publish a space's files and Velven hosts them at an address of the space's own. Each version is checked for safety before it goes live, then plays on the space's Velven page with sign-in, leaderboards and saves ready to use. One command does it: the quickstart shows how.
Or link a space where it already runs. Velven lists spaces on 7 hosts for now, chosen because each one lets a creator prove the site is theirs. More hosts come as that proof exists for them. Every space plays inside the Velven page, so the site has to allow velven.ai to frame it. A site that blocks framing is listed once it allows it.
If you build a space, size it to the window rather than to a fixed ratio, so it works on every screen.
