Checking on every keystroke feels fast, but it fires a lookup for every half-typed name, and the platforms that matter most (Instagram, TikTok and X) push back hard against that kind of automated traffic. When a platform blocks a lookup, the page a checker gets back can look exactly like a missing account.
handle.tools checks once, when you press Enter, then streams each platform's answer as it lands. Each check is built for its platform and tested with real and made-up names. When we can't be sure, the row says Likely taken or Could not verify, with a link to check by hand, instead of a green tick you might trust.
When we opened Instant Username Search it showed a consent screen for personalised advertising partners before the search. That's a normal way to fund a free tool, but it means your visit is shared with ad networks.
handle.tools has no display ads, and we don't send the names you search to analytics. The site is funded by domain-registrar links when you choose to buy a domain, plus an optional Pro plan that's launching soon.
Every search also checks 15 domain extensions and shows when a taken domain expires. You get a 0–100 identity score for how consistently you can claim the name, variations to try when it's taken, and one-click links to each platform.
When you have a few candidates, the bulk username checker puts them side by side and ranks them. When you have none, the username generator suggests 20 at a time in 60 styles, and the short username generator finds rare 3 to 6 letter handles.
Write a bio that fits each platform with the bio generator, make profile QR codes with the social QR code generator (28 platforms, PNG and SVG), or see how rare your handle is with the username rarity checker.
Every tool on handle.tools is free, with no account.
Type a name in the box above and press Enter. Rows fill in as each platform answers, so you still see results within a second or two, just without the guesswork.
