Reverse Username Search — Find All Accounts by Username (2026)

Updated: August 2026 · 175+ platforms searched

What is a Reverse Username Search?

A reverse username search finds all online accounts that share the same username across different platforms. Most people reuse usernames — if someone is "cooluser99" on Instagram, they're likely "cooluser99" on Twitter, Reddit, TikTok, and more.

This makes username searching one of the most effective ways to map someone's complete online presence.

How Lullar's Username Search Works

Lullar checks a username against 170+ platforms simultaneously, including:

• Social Media: Instagram, TikTok, X/Twitter, Facebook, Snapchat, Reddit
• Gaming: Steam, Twitch, Kick, Roblox
• Professional: GitHub, LinkedIn, Behance, Dribbble
• Dating: Tinder, Badoo, OnlyFans
• Messaging: Telegram, Discord, Skype
• Forums: Quora, Medium, WordPress, Tumblr

Results appear instantly and clicking any result takes you directly to that profile.

Lullar vs Sherlock, Maigret and WhatsMyName

These are the tools people actually compare, so here is the honest version. Site counts are from each project's own public data, checked August 2026.

Tool	Sites checked	Accepts an email?	How you run it
Maigret	3,000+	No — username only	Python, command line
WhatsMyName	716	No — username only	Web app or command line
Sherlock	481	No — username only	Python, command line
Blackbird	Several hundred	Yes	Python, command line
Lullar	175	Yes	Browser, nothing to install

If raw coverage is what you need, use Maigret. It checks roughly seventeen times as many sites as we do and it can pull profile metadata rather than just answering yes or no. We are not going to pretend otherwise, and for a serious investigation it is the right tool.

Two things Lullar does that the three most-recommended tools do not. First, it takes an email address, not just a username — Sherlock, Maigret and WhatsMyName are username-only, so if all you have is an address you cannot start with them at all. Second, there is nothing to install: no Python, no terminal, no dependency errors, which matters if you are checking one person once rather than running an investigation.

A reasonable order: start with Lullar because it takes seconds and accepts either an email or a username, then run Maigret if you need depth. They are not really substitutes.

Why People Reuse Usernames

Studies show that over 60% of internet users reuse the same username across multiple sites. This happens because:

• Memorable usernames are hard to create, so people stick with what works
• Many people want a consistent online brand or identity
• Username availability is limited on popular platforms

This behavior makes reverse username search extremely effective for OSINT (Open Source Intelligence) and personal investigations.

Tips for Username Searches

1. Try common variations: If "username" doesn't work, try "username_", "_username", "theusername", or "usernameofficial"
2. Check number patterns: People often add birth years — try "username98", "username99", "username2000"
3. Look for platform-specific patterns: Some people use different names on professional vs. personal platforms
4. Cross-reference results: Finding one profile can lead to discovering their other usernames

Common Use Cases

Online Safety: Verify someone you met online by checking if their username appears on other platforms with consistent information.

Hiring & Recruitment: See a candidate's public online presence beyond their LinkedIn profile.

Personal Branding: Check if your desired username is available across platforms before committing to it.

Finding Lost Friends: If you remember their old username from a game or forum, search it to find their current social media.

Frequently Asked Questions

How many platforms does Lullar search?

Lullar searches 170+ platforms across 13 categories including social media, gaming, professional networks, dating sites, forums, and more.

Is username searching legal?

Yes. Searching for publicly available usernames and profiles is legal. Lullar only provides links to public profiles. Always use results responsibly.

Can I find deleted accounts by username?

Lullar searches current profiles only. However, if a username was reregistered by someone else, that new profile will appear. For cached/deleted content, try archive.org.

What if someone uses different usernames?

Try searching their known username on Lullar, then check the profiles found for links to other accounts. People often link their various social media profiles together.

Is Lullar better than Sherlock or Maigret?

Not on coverage — Maigret checks 3,000+ sites and Sherlock 481, against 175 for Lullar, so for maximum reach Maigret wins. Lullar is faster for a one-off check because it runs in the browser with nothing to install, and it accepts an email address as well as a username, which Sherlock, Maigret and WhatsMyName cannot do. Most people use Lullar first and reach for Maigret only if they need depth.

Can I search by email instead of a username?

Yes. Paste an email address and Lullar checks the same 175 platforms. This is the main practical difference from the popular command-line tools, which are username-only — if all you have is an email, they give you nowhere to start.
