User Scanner: Scan a username across multiple social, developer, gaming and creator platforms to see if it’s available

Scan a username across multiple social, developer, and creator platforms to see if it’s available.
Perfect for finding a unique username across GitHub, Twitter, Reddit, Instagram, and more, all in one command.

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Note*: New modules are constantly getting added so this might have only limited, outdated output: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

See CONTRIBUTING.md for examples.
