About

runs-on.dev gives away subdomains under one domain that Advance Labs registered. Sign in with GitHub, claim a name like you.runs-on.dev, and it's live within seconds. No DNS panel, no yearly renewal on your end.

Say it plainly: this is a subdomain registry, not a TLD. A real top-level domain means an ICANN application. The 2026 round's evaluation fee alone is $227,000, before you've built or run a registry to back it. That's not a plausible route to a distinctive-looking address for a side project.

runs-on.dev gets the same feeling, a name that isn't vercel.app or github.io, for the price of one domain: about $10 a year. Every name you claim lives under runs-on.dev, which Advance Labs registered and answers for.

Free subdomains under a memorable root are a genuinely useful thing to give away. They make side projects, personal sites, and one-off tools look like they belong to someone, without asking anyone to run their own DNS. The idea isn't new, and it shouldn't have to be: is-a.dev, js.org, and eu.org all did it first, and runs-on.dev exists because that pattern is worth having more than once.

Advance Labs is the registrant of runs-on.dev and the party responsible for what runs under it. Advance Labs builds and ships its own software products; this registry is one of them, operated the same way it operates everything else: in the open, with the source and the rules on GitHub. See the policy for what that responsibility actually covers, and Advance Labs's own guide on picking a custom domain ending without going through ICANN.

Every claim, every hosting record, and every rule CI enforces lives in the public repo: github.com/zordhalo/runs-on.dev. Nothing about how a name gets claimed or reclaimed happens outside git history.
