325 expired .io domains with backlinks, free to browse. Referring domains, Wayback-verified age, availability re-checked. Masked until reveal.
This page lists 325 expired .io domains with backlinks. Each has expired, is available to register, and has referring domains that survived the original site going offline. Names are masked until you reveal them. Every metric is open. The .io extension is used almost entirely by software companies and developer projects, so expired .io domains tend to carry links from GitHub, Hacker News and technical documentation rather than from general press.
Every .io listing is verified the same way as the rest of the directory. Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing that turns out to be registered is removed. Referring domains are counted from the Common Crawl web graph, a public crawl of the web, not from a paid link index. History comes from the Internet Archive: the Wayback Machine snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and archive history into one 0 to 100 grade, computed across the whole directory.
Compare the .io listings on age, referring domain band, named linking sources, archive history and Revised Score before revealing any of them. Sort and filter within the extension with a Pro plan, or browse the featured order for free.

Yes, when the site you build continues what the domain was. Google's site reputation abuse policy targets expired domains repurposed to host unrelated content. Read the archive history and the category on the listing before you reveal it, and build something the old links would still make sense pointing at.
