Username Availability Checker
Check if your desired username is available across Instagram, TikTok, X, GitHub, Steam, Twitch, Reddit, and 100+ more platforms — all in one search. Free and instant.
Spokeo reveals the real name, phone, address, and background behind any username.
Search on Spokeo →How the username checker works
- Enter your desired username in the box above.
- Lullar generates the public profile URL on every supported platform — Instagram, TikTok, GitHub, Steam, Twitch, Reddit, Discord, and many more.
- Click any card to open that platform — if a profile loads, the username is taken; if you see a 404, it's available.
- Repeat with different variations (numbers, underscores) until you find a name available everywhere.
Frequently Asked Questions
Is this username availability checker free?
Yes — 100% free, no signup or credit card required. The check happens in your browser using direct profile URLs.
Which platforms can I check?
Instagram, TikTok, X (Twitter), Facebook, Snapchat, Reddit, LinkedIn, Threads, Bluesky, GitHub, Steam, Twitch, Kick, Roblox, Discord, Spotify, SoundCloud, Bandcamp, Pinterest, and 80+ more — all checked in one search.
How is this different from Namechk or Knowem?
Lullar is free with no signup, covers more global platforms (VK, Weibo, Xiaohongshu, Eksi Sozluk, Pikabu) and links you straight to the profile so you can verify yourself rather than trusting an opaque API.
Will my username search be private?
Yes — the page generates URLs locally in your browser. No data is sent to Lullar's servers other than normal pageview analytics.
