Awesome static analysis

Static program analysis is the analysis of computer software that is performed without actually executing programs (analysis performed on executing programs is known as dynamic analysis). — Definition by Wikipedia

This is a collection of static analysis tools and code quality checkers for all programming languages. Explanation: [OSS] stands for Open-Source-Software, [PROPRIETARY] stands for proprietary software. Pull requests are very welcome!
