Three free tools for sizing up a domain name before you buy it, sell it or build on it. Each one answers a different question: how old the name is, what it was used for, and how many people want it. They’re free, there’s no sign-up, and every check runs on live public data.
The tools
- Domain Age Checker
Shows when a domain was registered, how old it is, when it expires and which registrar holds it. The data comes straight from the registry’s own record. - Domain History Checker
Shows a domain’s past in the Wayback Machine, year by year. You can see when it first went online, which years it was a live site, and when it was parked or switched off. Every year links to a saved copy of the site. - Domain Extension Checker
Takes a name and checks it across 24 popular extensions, from .com and .net to .ai, .io and the main country codes. You see how many are already taken and which ones still look available.
Using them together
Each tool covers a gap the others leave. The registration date only tells you how long the current owner has held the name. If the domain dropped and was registered again, the clock starts over, and the history checker is where the earlier years show up. The extension count adds the market’s view. A name taken in 20 extensions is a name a lot of people have paid for.
Run all three on a domain you’re thinking about buying and you’ll know more about it in a minute than most listings tell you.
