About
What this is
runs-at.dev gives away subdomains under one domain, runs-at.dev. Sign in with GitHub, claim a name like you.runs-at.dev, and it's live within seconds. No DNS panel, no yearly renewal on your end.
It is not a top-level domain
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.
Note
runs-at.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-at.dev, which its operator registered and answers for.
Why it exists
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-at.dev exists because that pattern is worth having more than once.
Who runs it
runs-at.dev is registered and operated by @preetmendpara, the party responsible for what runs under it. It is operated in the open, with the source and the rules on GitHub. See the policy for what that responsibility actually covers.

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