Username Checker: Availability on 50 Sites

Check a username, brand name or handle on 50 sites at once. For every site you get taken, available or unknown, and the profile link where it is taken.

Sites covered:

• Developer: GitHub, GitLab, Bitbucket, Docker Hub, dev.to, Hacker News, Keybase, Codewars, Hugging Face, LeetCode, Lobsters, Launchpad, Scratch
• Social: Bluesky, Mastodon (mastodon.social), Telegram, Pinterest, Snapchat, TikTok, VK, Tumblr, Gravatar, Wikipedia, Disqus
• Video and music: Twitch, Dailymotion, SoundCloud, Bandcamp, Mixcloud
• Gaming: Steam, Chess.com, Lichess, Roblox, Minecraft, Speedrun.com, itch.io
• Writing and creative: Medium, Substack, WordPress.com, Wattpad, Dribbble, Flickr, DeviantArt
• Other: Duolingo, Trello, Patreon, Gumroad, About.me, OpenStreetMap, Pastebin

Every site uses a check that was tested from Apify's servers against a known account and a random name before shipping. When a site does not give a clear answer, the row says unknown and you are not charged for it.

No accounts, no API keys, no proxy. $0.0005 per answered check, no start fee.

What you get per username and site

• username, site, category
• status: taken, available or unknown
• profileUrl (when taken), checkedUrl, httpStatus, checkedAt

The run summary lists, for each username, how many sites it is taken and available on, and where it is taken.

Example input

Is a brand name free before you launch?

{
  "usernames": ["acmeboards"]
}

Where does a creator have accounts? Only list the sites where the name is taken:

{
  "usernames": ["mkbhd"],
  "onlyTaken": true
}

Developer platforms only, for three candidate project names:

{
  "usernames": ["fastqueue", "quickq", "qflow"],
  "categories": ["developer"]
}

Example output

[
  { "username": "nike", "site": "GitHub", "category": "developer", "status": "taken", "profileUrl": "https://github.com/nike", "httpStatus": 200 },
  { "username": "nike", "site": "Twitch", "category": "video", "status": "taken", "profileUrl": "https://www.twitch.tv/nike", "httpStatus": 200 },
  { "username": "nike", "site": "Bluesky", "category": "social", "status": "available", "profileUrl": null, "httpStatus": 400 }
]

Uses

• Naming and launches: check a product, company or project name across platforms before you commit
• Brand protection: see where your brand's handle is held, and by whom (follow the profile links)
• Creator and company research: find someone's other public profiles from one handle
• Handle hunting: test a list of candidate handles in one run

Pricing

• $0.0005 per site check with a taken or available answer (50 sites = $0.025 per username)
• Unknown answers are free. No start fee.

Notes

• "Taken" means an account or page with exactly that name exists. Some sites match names without case (GitHub, Twitch); a few are case-sensitive.
• Bluesky is checked as name.bsky.social; custom-domain handles are not covered. Mastodon is checked on mastodon.social only.
• Instagram, X/Twitter, Facebook, LinkedIn, Reddit and YouTube are not included: they do not answer reliably without a login or proxy.
• Only use this on public profile existence. It does not read private data.
