🚀 User Scanner: Find Your Perfect Username Across All Platforms in Seconds ⚡

Tired of opening tabs and hunting site-by-site to see if your favorite username is taken?

user-scanner fixes that , fast, from your terminal, with clear color-coded output. Perfect for developers, creators, and anyone who wants a consistent online identity without the busywork.

Github: https://github.com/kaifcodec/user-scanner

Features

✅ Check usernames across social networks, developer platforms, and creator communities.
✅ Clear Available / Taken / Error output for each platform.
✅ Robust error handling: It prints the exact reason (e.g. Cannot use underscores, hyphens at the start/end)
✅ Fully modular: add new platform modules easily.
✅ Wildcard-based username permutations for automatic variation generation using provided suffix
✅ Command-line interface ready: works directly after pip install
✅ Can be used as username OSINT tool.
✅ Very low and lightweight dependencies, can be run on any machine.

Installation

pip install user-scanner

Usage

Scan a username across all platforms:

user-scanner -u <username>

Optionally, scan a specific category or single module:

user-scanner -u <username> -c dev
user-scanner -l # Lists all available modules
user-scanner -u <username> -m github
user-scanner -u <username> -p <suffix>

Generate multiple username variations by appending a suffix:

user-scanner -u <username> -p <suffix>

Optionally, scan a specific category or single module with limit:

user-scanner -u <username> -p <suffix> -c dev
user-scanner -u <username> -p <suffix> -m github
user-scanner -u <username> -p <suffix> -s <number> # limit generation of usernames
user-scanner -u <username> -p <suffix> -d <seconds> #delay to avoid rate-limits

Note*: New modules are constantly getting added so this might have only limited, outdated output:

Module guidelines:
This project contains small "validator" modules that check whether a username exists on a given platform. Each validator is a single function that returns a Result object (see core/orchestrator.py).

Result semantics:

Result.available() → available
Result.taken() → taken
Result.error(message: Optional[str]) → error, blocked, unknown, or request failure (include short diagnostic message when helpful)

Follow this document when adding or updating validators.

├── community/  # Community platforms (forums, niche sites)
├── gaming/     # Gaming sites (chess.com, and many more(upcoming))

Module guidelines:

Each module must define a validate_<site>() function that takes a username and returns:
- 1 → Available
- 0 → Taken
- 2 → Error / Could not check
Use httpx for requests, colorama for colored output.
Optional: modules can define a CLI parser if they support custom arguments.

Created InstaScrape an Async Instagram Comment Scraper, looking for feedbacks and contributions.

kaifcodec — Wed, 29 Oct 2025 11:51:40 +0000

🚀 InstaScrape → Async Instagram Comment Scraper

Visit: Github

Scrape all parent comments from any Instagram Reel with automated login, async speed, real-time progress, and clean exports — no manual cookie copying required.

✨ Features

✅ Automated Login: cookie.json persistence with iat + expiry, no manual cookies needed.
🔄 Self-healing Auth: detects expired cookies mid-run, prompts relogin, resumes automatically.
⚡ Async Engine: powered by httpx.AsyncClient with requests-per-second throttling.
📊 Progress Tracking: accurate percent and ETA from Instagram’s comment count.
📁 Dual Exports: TXT and JSON files saved in timestamped folders.

📦 Requirements

Python 3.9+
Dependencies:

pip install -r requirements.txt

🛠️ Installation

git clone https://github.com/kaifcodec/InstaScrape
cd InstaScrape
pip install -r requirements.txt

▶️ Usage

python3 main.py

Enter the Instagram Reel URL (e.g., https://www.instagram.com/reel/SHORTCODE/).
Set Max requests per second (5-7 recommended). Adjust for stability.
On first run, provide username/password; cookie.json is created and reused until expiry.

📁 Output

TXT: download_comments/txt/reel_comments_YYYYMMDD_HHMMSS.txt
JSON: download_comments/json/reel_comments_YYYYMMDD_HHMMSS.json Example JSON structure:

{
  "generated_at": 1700000000,
  "count": 123,
  "comments": [
    { "username": "user1", "text": "Nice!", "created_at": 1699999000 }
  ]
}

🔧 How it Works

Cookie Lifecycle: cookie.json stores iat and expiry; validated on startup & during requests.
Error Resilience: retries transient errors and refreshes cookies on 401/redirect-to-login.
Progress Accuracy: uses Instagram’s comment count to calculate percent & ETA.
Async Efficiency: httpx.AsyncClient with HTTP/2, keep-alive, and RPS limiter.

💡 Tips

Start with 5-7 RPS to minimize throttling; increase gradually.
Filenames use local time; switch to UTC by replacing datetime.now() with datetime.utcnow() in main.py.

⚠️ Disclaimer

Use responsibly. Comply with Instagram’s Terms of Service. Intended for personal or permitted use only.

# install
pip install user-scanner

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 john_doe@gmail.com   # single email scanning 
user-scanner -u john_doe             # single username scanning

Verbose mode

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

user-scanner -v -e johndoe@gmail.com -c dev

Output:

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

Selective scanning

Scan only specific categories or single modules:

user-scanner -u john_doe -c dev                # developer platforms only
user-scanner -e john_doe@gmail.com -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.dev import github

async def main():
    # Engine detects 'email_scan' path -> returns "Registered" status
    result = await engine.check(github, "test@gmail.com")
    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": "test@gmail.com",
        "category": "Dev",
        "site_name": "Github",
        "status": "Registered",
        "url": "https://github.com",
        "reason": ""
}

Using Proxies

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

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

This will:

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

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.

CLI based Youtube video downloader written in python with advanced features — Need contributors and feedback

kaifcodec — Tue, 16 Sep 2025 17:51:41 +0000

Hey devs,

I recently built a command-line YouTube downloader in Python called ytconverter. It’s designed to fetch videos directly from YouTube and convert them into formats like MP3 and MP4. The goal was to make a simple, functional tool without external GUIs or bloated software — just clean CLI efficiency.

Key features:

Download YouTube videos
Convert to various formats (MP3, MP4, etc.)
Handles basic metadata
Easy to set up and use
If you're someone who likes working with Termux, CLI tools, or Python automation, this might be useful for you.

The project is open-source, so feel free to try it out, suggest improvements, or even contribute if you're interested.

Here’s the repo:

https://github.com/kaifcodec/ytconverter

For any error, contact: kaifcodec@gmail.com
Let me know what you think! Suggestions, critiques, or PRs are all welcome.

Thanks!
