Instantly check if a username is available across 18 social, creative, and gaming platforms plus popular domains. Type a username below, or pick one from our username generator.
Finding out whether a username is free usually means visiting every platform one by one and searching manually. This username availability checker does it in a single step. Enter the handle you want, and the tool instantly builds the exact profile link for that username on 18 major platforms, plus registration links for popular domains.
Click any platform link and it opens that username's profile page in a new tab. The result tells you everything: if a real profile loads, the name is already taken. If you land on a "user not found" or 404 page, the username is available and ready to claim. Because you check on the platform itself, the answer is always live and accurate — no guessing, no outdated cached data.
Using the same username everywhere makes you easy to find and recognize. Whether someone looks for you on Instagram, GitHub, or YouTube, one consistent handle builds a stronger personal or business brand than a different name on each platform.
Popular handles disappear fast. Even if you only use two or three platforms today, claiming your username everywhere stops others from taking it later — or worse, impersonating you on a platform where your name is still unclaimed.
Checking 18 platforms by hand is slow and easy to get wrong. A single search here gives you every link at once, so you can confirm availability across all of them in a couple of minutes instead of half an hour.
A username that is free on social platforms but whose matching .com is taken can create confusion down the line. Checking handles and domains side by side helps you pick a name you can own consistently across social media and the web.
The checker spans social networks, creative portfolios, developer platforms, and music and video services — the places where an online identity matters most:
Instagram, X (Twitter), TikTok, Facebook, Reddit, Pinterest, Tumblr, and Telegram — the core social platforms where most people search for a handle first.
Behance, Dribbble, DeviantArt, and Etsy — essential for designers, artists, illustrators, and makers who want a consistent creative identity.
GitHub and Medium — where developers, writers, and professionals build a public presence and portfolio.
YouTube, Twitch, SoundCloud, and Spotify — for creators, streamers, musicians, and podcasters who need a memorable channel or artist handle.
Alongside social handles, the checker links to .com, .net, .io, and .co domain searches, so you can secure a matching website and custom email address on your own brand.
Enter a username in the box and click Check. The tool builds direct links to that username's profile URL on 18 platforms. Click a platform to open the link: if it loads a profile, the username is taken; if you see a "not found" or 404 page, it's available to claim.
Yes. One search generates availability links for all 18 supported platforms plus four domain extensions at the same time. You then click through to each platform to confirm, which gives the most accurate, real-time result.
A 404 or "user not found" page means no account exists with that username on that platform, so the handle is available for you to register. If the link loads an actual profile, the username is already taken.
Yes, completely free with no registration or sign-up. You can check as many usernames as you like across all supported platforms and domains.
You can check Instagram, X (Twitter), TikTok, Facebook, YouTube, GitHub, Reddit, Pinterest, Twitch, Medium, Behance, Dribbble, DeviantArt, SoundCloud, Spotify, Tumblr, Etsy, and Telegram, plus .com, .net, .io, and .co domains.
No. The checker runs entirely in your browser. The usernames you check are never sent to our servers and never stored. Once you close the page, nothing is kept.
Checking first saves time and protects your brand. It lets you find one handle that is free across every platform you care about, so your identity stays consistent and no one can impersonate you on a platform where your name is unclaimed.
In almost all cases, yes. However, some platforms reserve certain names, block trademarked terms, or have minimum length rules. Availability shown here reflects whether a profile currently exists; the platform's own signup form is the final confirmation.
If your username is free on the platforms that matter to you, register it on all of them right away — even ones you don't plan to use yet. Consistent handles across platforms build a recognizable identity and stop others from taking the name later.
A matching domain lets you run a website and a custom email address on your own brand. Even if you don't need a site today, owning the domain protects your name and can be set up later.
Popular handles get taken fast. If your username isn't available on a must-have platform, head back to the username generator for more ideas, or try adding your profession, city, or a relevant keyword.
