A Source Code Plagiarism checker is a software tool or program that examines the source code of computer programs to identify existing errors or issues, without the actual execution of the code. In other words, these tools are designed to analyze code at a static level, meaning they examine the code as it is written, without running or executing the program.

Source code checkers are commonly used in software development and quality assurance processes to improve code quality, maintainability, and security. In all a Source Code Checker is an automated tool that scans source code files to identify a wide range of issues, including:

It helps in detecting code that may lead to runtime errors, crashes, or unexpected behavior.

Assists in identifying vulnerabilities such as SQL injection, cross-site scripting (XSS), and buffer overflows.

By analyzing code complexity metrics one can improve code readability and maintainability.

Identifying duplicated code can be a source of maintenance issues.

Source code detector helps in detecting code that may lead to suboptimal performance or resource leaks.
