Name Checker
One pass, ten platforms - check whether a username or social handle is still free without visiting each site by hand.
Best-effort check - some platforms block automated queries (shown as “unknown”).
About Name Checker
Name Checker takes a single username and queries ten popular platforms in one sweep: GitHub, GitLab, Reddit, X/Twitter, Instagram, YouTube, Twitch, Pinterest, Medium and npm. Each is reported as taken, available or unknown. The lookups run server-side from our EU infrastructure, so your browser never has to reach out to ten different domains itself.
It works by requesting each platform's public profile URL and reading the HTTP status code. A 404 (page not found) means the handle is likely free, a 200 (page exists) means a profile is already there, and any other response - a redirect, rate limit or bot wall - is reported honestly as unknown rather than guessed. Every request has a six-second timeout and runs concurrently, so a full sweep finishes in seconds.
Because large platforms increasingly block automated traffic, treat the result as a strong first signal rather than a reservation. An available result is a good candidate to claim, but the only way to secure a handle is to register it on the platform itself. Usernames may contain letters, digits, dots, hyphens and underscores, up to 40 characters.
Consistent handles make a brand or personal identity easier to find and harder to impersonate. The tool sends only the username you type - no account, no third-party analytics, no trackers - and the checks originate entirely from European servers.
How to use it
- 1Type the username or handle you want to check into the input field.
- 2Use only letters, numbers, dots, hyphens or underscores, up to 40 characters.
- 3Run the check - all ten platforms are queried at the same time.
- 4Read each result: available (likely free), taken (profile exists) or unknown (couldn't be determined).
- 5Confirm any available handle by registering it directly on that platform.
Common use cases
- -Picking a consistent brand or project name across GitHub, npm and social platforms before a launch.
- -Reserving a personal handle that matches across your main networks.
- -Checking whether a desired GitHub org or npm author name is free for a new open-source project.
- -Quickly vetting alternative spellings when your first-choice handle is already taken.
- -Spotting where someone may be squatting on or impersonating your brand on platforms you don't actively use.
Frequently asked questions
- How does Name Checker know if a username is available?
- It requests each platform's public profile URL and reads the HTTP status code. A 404 (not found) indicates the handle is likely free, a 200 (page exists) indicates it is already taken, and any other response is reported as unknown.
- Which platforms does it check?
- Ten in a single pass: GitHub, GitLab, Reddit, X/Twitter, Instagram, YouTube, Twitch, Pinterest, Medium and npm.
- Why do some results say unknown?
- Large platforms often block or throttle automated requests with bot walls, redirects or rate limits. When the response isn't a clear 404 or 200, the tool reports unknown instead of guessing, so you are never shown a false result.
- Does an available result reserve the username for me?
- No. It is a best-effort signal that the handle appears unclaimed. To actually secure it, register the username on that platform yourself.
- What characters can a username contain?
- Letters, numbers, dots, hyphens and underscores, up to 40 characters, which matches the character sets most platforms allow.
- Is my search private?
- Yes. Only the username you type is used, the lookups run from EU-based servers, and there are no trackers, accounts or third-party analytics involved.
