user-scanner 1.4.1.2

Check username availability across multiple popular platforms

User Scanner

---

A powerful 2-in-1 OSINT suite engineered for deep Email and Username Intelligence.

With 295+ total scan vectors—including 110+ email-integrated sites and 185+ username platforms—you can map digital footprints, analyze target behavior, uncover interests, and verify account registrations in seconds.

The ultimate reconnaissance tool for hunting down targets using just an email or username—now fully integrated with Hudson Rock for instant data breach intelligence.

Features

• ✅ Deep Email & Username OSINT: Look up email registrations and perform advanced username profiling across 295+ platforms.
• ✅ Profile Data Extraction: Goes beyond basic availability checks to scrape and extract rich metadata, account details, and digital footprints from target profiles.
• ✅ Dual-Mode Engine: Run targeted email campaigns, massive username sweeps, or simultaneous dual-identifier scans.
• ✅ Granular Status Reporting: Get crystal-clear results (Registered/Available for emails; Found/Not Found/Error for usernames) backed by precise exception handling.
• ✅ Modular & Extensible: Built on a highly decoupled, modular architecture, adding new platform modules takes just a few lines of code.
• ✅ Mass Bulk Scanning: High-throughput processing for bulk lists of usernames and emails via structured input files.
• ✅ Permutation Generator: Wildcard-based username variation generation to catch typosquatting or alternative aliases.
• ✅ Multi-Format Export: Clean console output paired with structured, automated exports to JSON and CSV for easy pipeline integration.
• ✅ Advanced Proxy Rotation: Built-in proxy pivoting with automated rotation and pre-scan health checks to bypass strict rate-limiting.
• ✅ Smart Auto-Update System: Keeps your signatures and modules fresh with interactive, seamless PyPI update prompts.

Important Flags

See Important flags here and use the tool powerfully

Usage

Basic username/email scan

Scan a single email or username across all available modules/platforms:

user-scanner -e [e-mail]   # single email scanning 
user-scanner -u johndoe             # single username scanning 

Verbose mode

Use -v flag to show the url of the sites being checked

user-scanner -v -e [e-mail] -c dev

Output:

  ...
  [✔] Huggingface [https://huggingface.co] ([e-mail]): Registered
  [✔] Envato [https://account.envato.com] ([e-mail]): Registered
  [✔] Replit [https://replit.com] ([e-mail]): Registered
  [✔] Xda [https://xda-developers.com] ([e-mail]): Registered
  ...

Selective scanning

Scan only specific categories or single modules:

user-scanner -u johndoe -c dev                # developer platforms only
user-scanner -e [e-mail] -m github   # only GitHub

Bulk email/username scanning

Scan multiple emails/usernames from a file (one email/username per line):

• Can also be combined with categories or modules using -c , -m and other flags

user-scanner -ef emails.txt     # bulk email scan
user-scanner -uf usernames.txt  # bulk username scan

Library mode for email_scan

Only available for user-scanner>=1.2.0

See full usage (eg. category checks, full scan) guide library usage

• Email scan example (single module):

import asyncio
from user_scanner.core import engine
from user_scanner.email_scan.shopping import etsy

async def main():
    # Engine detects 'email_scan' path -> returns "Registered" status
    result = await engine.check(etsy, "[e-mail]")
    json_data = result.to_json() # returns JSON output
    csv_data = result.to_csv()   # returns CSV output
    print(json_data)             # prints the json data

asyncio.run(main())

Output:

{
  "email": "[e-mail]",
  "category": "Shopping",
  "site_name": "Etsy",
  "status": "Registered",
  "url": "https://www.etsy.com",
  "extra": {
    "id": 98832,
    "name": "test123",
    "username": "test123",
    "gender": "private",
    "is_seller": "No",
    "has_public_page": "No",
    "stats": "0 followers | 0 following | 0 favorites",
    "privacy": "Items are Public | Shops are Public",
    "joined": "2010-09-19 05:04:06",
    "last_profile_update": "2020-07-31 01:40:24",
    "avatar": "https://i.etsystatic.com/site-assets/images/avatars/default_avatar.png?width=400"
  },
  "reason": ""
}

Using Proxies

Validate proxies before scanning (tests each proxy against google.com):

user-scanner -u johndoe -P proxies.txt --validate-proxies # recommended

This will:

1. Filter out non-working proxies
2. Save working proxies to validated_proxies.txt
3. Use only validated proxies for scanning

• Use the --hudson flag to check if a username or email has been exposed in infostealer malware logs.

user-scanner -e [e-mail] --hudson   # for email check
user-scanner -u johndoe --hudson             # for username check

🛠️ Troubleshooting

Some sites may return 403 Forbidden or connection timeout errors, especially if they are blocked in your region (this is common with some adult sites).

• If a site is blocked in your region, use a VPN and select a region where you know the site is accessible.
• Then run the tool again.

These issues are caused by regional or network restrictions, not by the tool itself. If it still fails, report the error by opening an issue.
