Easy-to-use tool that makes it simple to view all available domain names at once. It covers most if not all TLD's with no additional fees or charges involved. Not many features but easy to use (buttons). I've been using this service since 2014 however they did introduce an upgrade around 3 years ago called "Domains Index Premium" which is more expensive than their standard version but has some extra options like bulk deletion of old expired domains. Also there have been changes and updates as well so even though you're paying more now, there may be times when the pricing will go down again in future. The main benefit here is getting access to all the information about every single domain name within seconds instead of doing them manually. I like that it has a lot of different subdomains including top level domain names. It's easy to use and very user friendly. It is also quite inexpensive compared to other companies. There really isn't anything that i dislike about domains index. If you want to keep up with all the latest domain changes this is the best option. It allows me to quickly access the most recent updates and purchase them at a low price.
