Code Climate is an automated code analysis tool that grades your app on test coverage, complexity, duplication, security, style and more. It comes with a free two-week trial. Even if you’re not prepared to take the plunge to pay, Code Climate can give you lots of valuable insight into the code quality of your latest personal project, or—if your team is open to the idea—of the product or service you’re building. As a software developer, you probably have a sense for code smells: things that could be better. Yet, it can be difficult to know where to start when you feel like lots of things are wrong with your code. Code Climate is a simple tool to give you an actionable starting point when trying to make things better.
