Find available .io domains for startups
.io is familiar in software and startup communities, but a good domain still depends on the name before the dot. Generate distinctive labels instead of forcing awkward modifiers onto a taken word.
NameFinder checks .io registration status through a verified RDAP endpoint and displays estimated standard Porkbun pricing until you confirm at checkout.
Real RDAP Verification
Every name is verified live against official WHOIS/RDAP registries across .com, .io, .ai, .dev, and .app — no stale, cached guesses.
Multi-Namespace Handles
Check matching social handle availability across GitHub, npm, YouTube, X, and Instagram in one pass alongside your domain search.
Honest Registrar Prices
Transparent wholesale prices directly from Porkbun, Namecheap, and Cloudflare — zero affiliate price markups or registration traps.
