CodeScene identifies patterns in the evolution of your code. This gives you the power to predict its future and to find the code that is hard to evolve and prone to defects. The investigation takes only minutes but saves you from future limitations, bottlenecks or maintenance issues.

CodeScene gives you a better understanding of your software systems. Here are just a few of all the questions that CodeScene will help you find answers to:

Which part of the code might become productivity bottlenecks?
Which parts of the code will be hard to maintain?
What is the technical risk when a key developer leaves the project?
Which parts of the code should we improve to get a real productivity and quality gain?
How is the knowledge distribution between teams in your codebase?
