24 alternatives to Free .io Availability Checker
Someone is selling a list of available three, four, and five letter .io domains that are available for $20. This - https://gist.github.com/4111298 - generates a list of available .io domains of any length (user specified). And, its free. (I'm away from my computer, so it isn't tested, but I ran it in repl.it). Edit - this is the seller - http://news.ycombinator.com/item?id=4804627

I tend to use AI to brainstorm domain names, but I kept wasting time pasting each idea into Namecheap to see if they were available. So I built DotComBuddy - it generates ideas (using DeepSeek V3 - switched from GPT-4o after realizing quality was just as good) and checks availability in real time via Name.com’s API. Built with Next.js and Vercel’s AI SDK, the app gives you a table of available domains with their price. 10 free searches to try it out, then $9/year (what I’d pay to never do this manually again). Sharing this for anyone else tired of switching tabs to check domains. Happy…

I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game.
