VelvenBot
If this user agent showed up in your logs, someone listed a page of yours on Velven, or tried to. Velven is a leaderboard for spaces built with AI; it links to your page and never copies it.
What it fetches
One GET of the listed URL, following redirects, reading at most the first 512 KB of HTML for the title, description and preview image. When a creator proves they built the page it also reads the page head for a velven meta tag, or /.well-known/velven.
After that, a liveness probe every day or so: one GET, the body discarded. A page that stops answering leaves the board until it answers again.
Nothing is fetched that a visitor to Velven would not load themselves, and no page is crawled for links.
How to recognise it
Mozilla/5.0 (compatible; VelvenBot/1.0; +https://velven.ai/docs/bot)
Requests come from Vercel's network, so the address changes; the user agent does not.
Keeping it away
Answer the user agent with 403 and the page is never listed and drops off the board on the next probe. If a page of yours is already listed and you want it gone, use the report button on its Velven page or email privacy@velven.ai.
