About this list
This page lists 407 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 our own web crawl, not from a paid link index. Site history comes from archived captures: the archived snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and site history into one 0 to 100 grade, computed across the whole directory.
Compare the .io listings on age, referring domain band, named linking sources, site history and Revised Score before revealing any of them. Browse the featured order here, or use the filters to pivot into the full directory. Search, filters and sort are free, signed in or not.

How do I find expired .io domains with backlinks?
Browse this page. Every .io domain listed has expired, is available to register, and has referring domains counted from our web crawl. The names are masked and the metrics are open. Reveal a listing to get its name, then register it at any registrar that offers .io.
How are the .io listings verified?
Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing found to be registered is removed. History comes from archived captures, referring domains from our web crawl, and Revised Score blends both into a 0 to 100 grade computed across the whole directory.
Are expired .io domains safe to use for SEO?
Yes, when the site you build continues what the domain was. Google's expired domain abuse policy targets expired domains repurposed to host unrelated content. Read the site history and the category on the listing before you reveal it, and build something the old links would still make sense pointing at.
