Three stand out:
β€’ marginalia.so β€” $48/yr via Netim. Poetic, unique, registrable today.
β€’ folio.ai β€” $74/yr via Netim (save $25 vs GoDaddy). Short, on-brand for research.
β€’ quorum.io β€” $37/yr via Netim. Clean + memorable, though .io licensing is shifting.
Want me to open the watchlist on marginalia.com ($3,800 premium, listed on Sedo) in case it drops?

Β§ 02Four registrars, one request

One source of truth.
Three price checks.

Vercel tells us whether a domain is actually registrable. GoDaddy, Namecheap and Netim tell us what it would cost you elsewhere. We reconcile the spread so you always know when to switch registrar β€” and when to walk away.
