Coverity Scan vs StyleCI: What are the differences?

Coverity Scan: Find and fix defects in your Java, C/C++ or C# open source project for free. Coverity's implementation of static analysis can follow all the possible paths of execution through source code (including interprocedurally) and find defects and vulnerabilities caused by the conjunction of statements that are not errors independent of each other; StyleCI: The PHP Coding Style Continuous Integration Service. StyleCI automatically analyses all of your pull requests and will display a build status within GitHub before you merge.

Coverity Scan and StyleCI can be primarily classified as "Code Review" tools.

Some of the features offered by Coverity Scan are:

• Test every line of code and potential execution path.
• The root cause of each defect is clearly explained, making it easy to fix bugs
• Integrates with GitHub and Travis CI

On the other hand, StyleCI provides the following key features:

• Fix PSR-1, PSR-2, PSR-5, Symfony and more.
• We watch all of your pull requests and automatically analyse them.
• Open Source
