Top Open Source Static Application Security Testing (SAST) Tools
Rate this post

Static code analyzers or SAST tools help find vulnerabilities in source code early. The code will later become the software. Here is a list of top open source SAST tools. Developers and security pros can use them. They can use them to make their applications more secure.

List of Open Source SAST Tools

15. Sobelow

Sobelow is meant for the targets in Phoenix Framework applications. It analyzes Elixir for common security issues.

16. VisualCodeGrepper

The specific languages this tool uses are given below: C++, C#, VB, PHP, Java, and PL/SQL.


YASCA is a type of software. It integrates one or more scanning tools and their features. It assesses the security of source code in many languages.

18. Checkmarx

It is not truly open-source. But, Checkmarx’s strength is that it offers a secure platform for static code analysis. It is highly reputed for its versatile functionality. It supports many programming languages and frameworks.

19. NodeJSScan

A static security code scanner (SAST) for Node or a SAST tool specifically designed for Node. Many JS applications, like NodeJSScan, scan source code for security issues. These issues are unique to the Node ecosystem. js environment.

20. Coverity

Coverity also has open-source and usage-based editions. These are free for projects like Gentoo. It is a robust static checker for many languages.

21. HCL AppScan

It was formerly known as IBM AppScan. This tool has a range of solutions for doing both static and dynamic tests for application security. It provides a detailed report of security issues.

22. RIPS

RIPS is an excellent static analysis solution. It is made specifically to find issues in PHP applications. It has both a high detection rate and detailed reports.

23. Horusec

It’s an OSS application. It analyzes code to show how insecure it is. It also finds bugs, vulnerabilities, and license issues in projects.

24. Phan

A PHP Code Check tool, which tends to minimize reporting of false alarms. It verifies certain features and it can also find some kinds of security flaws existing in the PHP code.

25. Security Code Scan

It is a tool. It can analyze the source code of the software. It tells the level of security and suggests improvements if needed. SANS has a NET application. It points out security flaws in the timeline. Developers use Visual Studio to write code or within CI/CD cycles.
