Secure code scanning tools

In terms of source code scanning, there is no-one-size-fits-all solution. There are also no scanning tools that can find zero false positives with a 100% accurate detection rate. Therefore, for the same programming language, it's common that we may apply at least two scanning tools for a cross-reference check.

Here are some commonly used open-source secure coding analysis tools, as in 2018. Note that we only list open source tools here:

Tools	Background and key characteristics of the scanning tool
Retire.JS	Detection of vulnerable JavaScript libraries, such as jQuery, AngularJS, Node, and so on. It provides the command line, grunt plugin, and also OWASP ZAP plugin for integration scanning.
Clang Static Analyzer	This provides standalone command line analysis for C, C++, and Objective C.
Flawfinder	A simple C/C++ code scanning...
