WhatsMyName App: Find Any Username Across 732 Platforms
WhatsMyName App is a free, open-source tool that searches over 732 websites simultaneously to find where a specific username exists. Type in any handle and it returns a list of platforms — from Reddit to TikTok to developer forums — where that username has a registered account. Results stream in real time, no account needed, no install required.

WhatsMyName App is an OSINT (open-source intelligence) tool built for username enumeration. It was created by Micah Hoffman, known in the security community as WebBreacher, and the full source code is publicly available on GitHub. Anyone can audit exactly what it does, contribute new platforms to its database, or run their own local version.
The tool works by sending a read-only request to each platform in its database using the username you enter. It checks whether the response matches a known pattern that confirms an account exists. If it does, the platform is marked as found. If it does not, it is marked as not found or returns an error if the site behaved unexpectedly.
The database currently covers 732 platforms across social media, gaming, coding communities, forums, dating sites, finance platforms, music and video services, tech communities, shopping, image hosting, news sites, and business networks. The list is maintained by the open-source community and updated regularly.
How to Use WhatsMyName App
The fastest way to use WhatsMyName App is through the web version on this site. No download, no account, no API key.
Go to the homepage
The tool is live on the homepage of this site. Navigate to the homepage and you will see the search bar immediately above the fold.
Enter a username
Type the username you want to search into the input field. Use the exact handle as it appears on social platforms — spelling and capitalisation matter. Most platforms are case-insensitive but some are not.
Click Search
Hit the Search button. WhatsMyName App begins checking all 732 platforms in parallel, running 20 simultaneous checks at a time.
Read the results as they stream
Results appear in real time as each check completes. You do not need to wait for the full scan to finish. Green or confirmed results mean an account was found. Red results mean no account exists. Error results mean the platform returned an unexpected response.
Click through to any found profile
Every confirmed result is a clickable link that opens the live profile on that platform in a new tab. You can verify the account directly.
Export your results
Once the scan is complete, export all found accounts to a CSV file with one click. The export includes the platform name, the direct profile URL, and the platform category.
The full scan typically completes in 30 to 90 seconds depending on your connection speed and how many platforms respond quickly.
Is WhatsMyName App Safe and Legal
Does it store what I search?
No. WhatsMyName App runs searches entirely within your browser session. The usernames you enter are not logged, not stored on any server, and not retained after you close the tab. The tool is stateless by design. Once your session ends, the search is gone.
This is verifiable. The source code is fully open on GitHub. Anyone can read exactly what happens when you submit a search. That level of transparency is one of the reasons WhatsMyName App is widely trusted in the OSINT and cybersecurity community.
Is it legal to use?
Yes, in most jurisdictions. WhatsMyName App only checks publicly accessible profile URLs — the same pages anyone could open manually in a browser. It does not bypass any authentication, access any private data, or scrape any content from the platforms it checks.
Looking up whether a username exists on a public platform is equivalent to typing that username into Google. It is not hacking, it is not data theft, and it does not violate any platform terms of service in a way that creates legal exposure for the person running the search.
That said, what you do with the results matters. Using WhatsMyName App to locate someone and then stalk, harass, threaten, or harm them is illegal regardless of the tool used. The tool itself is neutral. The intent and action are what the law evaluates.
In Indonesia specifically, using this tool to gather publicly available information for legitimate research, journalism, or personal auditing falls within lawful use under UU ITE as long as no private systems are accessed.
WhatsMyName App vs Other Username Search Tools
WhatsMyName App is not the only tool that does this. Here is how it compares to the most commonly used alternatives in the OSINT community.
| Tool | Sites checked | Install needed | Open source | Best for |
|---|---|---|---|---|
| WhatsMyName App | 732+ | No (web version) | Yes | Quick lookups, no setup |
| Sherlock | 400+ | Yes (Python CLI) | Yes | Terminal power users |
| Maigret | 3,000+ | Yes (Python CLI) | Yes | Deep investigations |
| Namechk | ~100 | No (web) | No | Brand availability |
WhatsMyName App vs Sherlock
Sherlock is a Python command-line tool that checks around 400 platforms. It is powerful for users comfortable with a terminal but requires Python installed on your machine and some technical setup. WhatsMyName App requires nothing. If you want results in 60 seconds from any device without touching a terminal, WhatsMyName App wins every time.
WhatsMyName App vs Maigret
Maigret is a fork of Sherlock that checks over 3,000 platforms and extracts additional profile data where available. It is the most thorough tool available but it is also the slowest and most technically demanding. It requires Python and produces large output files. WhatsMyName App is the right choice for fast, accessible lookups. Maigret is the right choice for deep professional investigations.
WhatsMyName App vs Namechk
Namechk checks around 100 platforms and is primarily designed for checking username or brand name availability before registration. It is not an OSINT tool. It does not confirm existing accounts in the same way and covers far fewer platforms. WhatsMyName App covers 7 times as many platforms and is built for finding existing accounts, not checking availability.
Who Uses WhatsMyName App
Security researchers
OSINT investigators use WhatsMyName App to enumerate a target's online presence as part of a digital footprint analysis. Finding every platform where a username appears is often the first step in building a comprehensive profile during a legitimate investigation. The tool lets researchers quickly identify pivot points — platforms where the subject is active — without running dozens of manual searches.
HR teams and recruiters
Hiring teams use WhatsMyName App to verify that a candidate's stated online profiles are consistent and to check whether additional accounts exist under the same handle. This is useful for senior hires or roles with public-facing responsibilities where online conduct is relevant to the position.
Journalists and investigators
Journalists use WhatsMyName App to quickly locate all public accounts associated with a person or alias during research. When covering a story involving an online identity, finding every platform where that identity is active provides corroborating sources and additional angles for investigation.
Individuals auditing their own footprint
Many people use WhatsMyName App simply to see where their own username appears online. It is a fast way to find accounts you signed up for years ago and forgot about, understand what information is publicly associated with your handle, and decide whether you want to close or update old profiles.
Frequently Asked Questions
How does WhatsMyName App username search work?
WhatsMyName App sends a read-only request to each platform in its database using the username you enter and checks whether the response matches a known account-found pattern. It runs 20 checks in parallel so 732 platforms are covered in seconds rather than minutes. No private systems are accessed and no content is scraped.
Is WhatsMyName App free?
Yes, completely free. There is no paid tier, no account required, and no limit on the number of searches you can run. The underlying dataset is open source and maintained by the community on GitHub.
Who created WhatsMyName App?
The tool was created by Micah Hoffman, known online as WebBreacher, an OSINT researcher and security professional. The source code is maintained on GitHub and accepts community contributions for adding new platforms to the database.
How many platforms does WhatsMyName App check?
WhatsMyName App currently checks 732 platforms. The database covers social media, gaming, coding and developer communities, forums, dating sites, finance platforms, music and video streaming, tech communities, shopping, image hosting, blogs, news, and business networks.
Why do some results show as errors?
An error means the platform returned an unexpected response during the check. This happens when a site is temporarily down, rate-limiting automated requests, or has changed its URL structure since the database was last updated. An error does not confirm or deny whether an account exists on that platform.
Can I export my results?
Yes. Once a search completes you can export all found accounts to a CSV file with one click. The export includes the platform name, the direct profile URL, and the platform category.
Does WhatsMyName App work on mobile?
Yes. The web version works in any mobile browser. Open the homepage on your phone, enter a username, and run the search exactly as you would on desktop. No app download is required.
Can I use WhatsMyName App to check username availability?
Yes. A not-found result generally means that username is not registered on that platform, which means it is available. This makes WhatsMyName App useful for checking username availability across hundreds of platforms at once before signing up for a new service or registering a brand handle.
How is WhatsMyName App different from just Googling a username?
A Google search returns whatever pages Google has indexed, which may be incomplete, outdated, or include irrelevant results. WhatsMyName App checks 732 platforms directly and in real time, returning only confirmed profile matches with direct links. It is faster, more thorough, and more accurate for this specific task than a general search engine.
What is OSINT and is WhatsMyName App an OSINT tool?
OSINT stands for open-source intelligence. It refers to the practice of collecting and analysing information from publicly available sources. WhatsMyName App is an OSINT tool because it gathers publicly accessible data — specifically whether a username exists at a public profile URL — without accessing any private or restricted information.
