**The user-scanner repository by kaifcodec is distributed under the MIT License, permitting unrestricted use, modification, and distribution provided the copyright notice and license terms are preserved.**

The open-source OSINT tool user-scanner provides username and email scanning capabilities across multiple platforms. Understanding the user-scanner license is essential for developers integrating this tool into their security research workflows or commercial applications. The project’s permissive licensing model ensures broad compatibility while maintaining attribution requirements.

## MIT License Terms for User-Scanner

The user-scanner project adheres to the **MIT License**, one of the most permissive open-source licenses available. This license grants you the rights to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software without restriction.

According to the `LICENSE` file located at the repository root, the license requires only that you include the copyright notice and permission notice in all copies or substantial portions of the software. The full license text resides in the [`LICENSE`](https://github.com/kaifcodec/user-scanner/blob/main/LICENSE) file, with the header line clearly stating:

```

MIT License

```

This permissive approach allows security researchers and developers to incorporate user-scanner into both open-source and proprietary projects without the copyleft restrictions found in GPL-style licenses.

## Core Architecture and Licensed Components

The MIT License covers all source files within the `user_scanner/` directory, including the modular scanning engine and asynchronous orchestrators that power the tool’s OSINT capabilities.

### Engine and Orchestrator Modules

The central coordination logic resides in [`user_scanner/core/engine.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/engine.py), which implements the `Engine` class for synchronizing username scans across multiple platforms. This module works in conjunction with [`user_scanner/core/orchestrator.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/orchestrator.py), which handles dynamic loading of scan modules, applies global CLI flags, and manages concurrency through asynchronous execution pools.

For email-based investigations, [`user_scanner/core/email_orchestrator.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/email_orchestrator.py) provides the `EmailOrchestrator` class that aggregates results from various email-scanning modules while maintaining the same MIT-licensed codebase.

### Result Handling Classes

The [`user_scanner/core/result.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/result.py) file defines the `Result` class, a standardized data structure used across all scanning modules to represent platform states—**available**, **taken**, or **error**. This consistent interface ensures that both username and email scanning operations return uniform results that support dictionary-like access and JSON serialization via the `to_json()` method.

## Implementation Examples Under MIT Terms

The following code examples demonstrate practical usage of user-scanner components, illustrating how you can leverage the MIT-licensed codebase in your own applications while maintaining compliance with the license terms.

Scan a username across multiple platforms using the core engine:

```python
from user_scanner.core.engine import Engine

engine = Engine()
result = engine.scan_user("example_user")

for platform, status in result.items():
    print(f"{platform}: {status}")

```

Perform asynchronous email OSINT investigations:

```python
from user_scanner.core.email_orchestrator import EmailOrchestrator

orchestrator = EmailOrchestrator()
email_result = orchestrator.scan_email("john.doe@example.com")

print(email_result.to_json())

```

These implementations import directly from the core modules located in the `user_scanner/core/` directory, utilizing the `Engine` class for username enumeration and `EmailOrchestrator` for email intelligence gathering. The returned objects provide both iterative access through `items()` and serialization via `to_json()`, reflecting the architectural patterns defined in [`user_scanner/core/result.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/result.py).

## Summary

- The user-scanner project operates under the **MIT License**, allowing commercial and non-commercial use with minimal restrictions.
- The full license text is contained in the repository’s `LICENSE` file at the root level.
- Core functionality is implemented across [`user_scanner/core/engine.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/engine.py), [`user_scanner/core/orchestrator.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/orchestrator.py), and [`user_scanner/core/email_orchestrator.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/email_orchestrator.py).
- The `Result` class in [`user_scanner/core/result.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/result.py) provides standardized output handling for all scanning operations.

## Frequently Asked Questions

### What license covers the user-scanner project?

The user-scanner project is released under the MIT License. This permissive license allows you to freely use, modify, and distribute the code, provided you include the original copyright notice and license text in any substantial copies of the software.

### Can I use user-scanner in commercial applications?

Yes. The MIT License explicitly permits commercial use, including incorporation into proprietary software products. You may sell copies of the software or use it as a component in commercial security tools without violating the license terms, as long as you maintain the required attribution notices found in the `LICENSE` file.

### Where is the full license text located?

The complete MIT License text resides in the [`LICENSE`](https://github.com/kaifcodec/user-scanner/blob/main/LICENSE) file at the root of the repository. The file begins with the line "MIT License" and contains the full legal text governing the use of all source files within the project, including those in `user_scanner/core/` and its subdirectories.

### Do I need to attribute the authors when modifying the code?

Yes. The MIT License requires that you include the original copyright notice and permission notice in all copies or substantial portions of the software. When modifying files such as [`user_scanner/core/engine.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/engine.py) or [`user_scanner/core/result.py`](https://github.com/kaifcodec/user-scanner/blob/main/user_scanner/core/result.py), you must preserve the original license header or include the attribution in your accompanying documentation to remain compliant with the user-scanner license terms.
