Vendors publish one server each. Stripe, Notion, Figma, Slack, Linear — one entry apiece, no competing copies.
What does produce dozens of entries under one name is hosting: 75 servers sit on
clauxel.com, 66 on alpic.live, most of them someone's staging
environment that ended up in the registry. They are listed here like everything else,
with whatever status they actually have.
