Which Is The Best Tool For Code Originality Check?

For the Code Originality Check, the best I can suggest is Codequiry, one of the best code plagiarism detection tools to give accurate results and an efficient algorithm. It has superseded MOSS for its much advanced and reliable features. The system is created around the source code detection system, and the results you can get are accurate and trustworthy. 

It is also effective in finding similarities in logic patterns and unique styles of code, ascertaining that the code submissions are original. First, the code does peer-to-peer checking and then detects the similarities from billions of code sources that are available online. You can see the checking progress in real-time and receive results in minutes and that too in detail with highlight snippets of matches.
