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

1. SonarQube

SonarQube is an open-source code quality inspection tool widely used for ongoing code quality inspection and assessment. It also enables automatic reviews with Static Code Analysis and finds Bugs, Code Smell, and Security in over 20 programming languages.

6. Clang Static Analyzer

It is part of the Clang project. It is a static analysis tool. It checks for vulnerability issues in C, C++, and Objective-C code. Forcing developers to write hard pseudocode rules and checking them with static analysis is not the same as having a tool. The tool can find many types of memory corruption and runtime errors.

7. Cppcheck

Cppcheck is a static analysis tool. It can analyze C/C++ code, which is widely used for developing software. The tool finds many mistakes. Compilers cannot find them, since they are common in C++ programs.

8. PMD

PMD analyzes Java source code. It looks for possible concerns in it. These include security risks, unneeded variables, and object creation. It also supports JavaScript and Salesforce. It handles encryption and compression. It supports Testking and 300-070 online dumps. It supports Twofold/Sendmail, pop-before-smtp, XML, Mac OS X, BSD/OS, Solaris/OS, HP-UX, and AIX. It also supports SSL and TLS. Namely, com Apex, PLSQL, Apache Velocity, XML, and XSL.

9. Flawfinder

Flawfinder is an analyzer tool. It reads C and C++ source code and shows the security weaknesses. It shows them by type, risk, explanation, and ways to fix the problem.

10. Semgrep

Semgrep is one such low-overhead, offline, open-source, static analysis tool. Users can create custom rules. They use them to check code for the right standards, errors, or desired patterns. It works with code in any language. It was made for fast and easy use. It has the potential for taint analysis and security audits.

11. MythX

MythX analyzes Ethereum smart contracts written in Solc and web3py. It detects security issues in Solidity smart contracts using static and dynamic analyses.

12. Infer

Infer is a static code analysis tool created by Facebook. It supports Java, C, C++, and Objective-C. Infer detects bugs in Droid and Apple apps. It also finds bugs in software written in these languages.

13. Kiuwan

Kiuwan is a code analysis solution. It covers over 30 programming languages. This lets the tool be put into DevOps pipelines. It is for live code analysis and real-time scanning of vulnerabilities.

14. Graudit

It is a sharp and compact script checker. It examines source code in owned programming languages. It looks for security breaches.

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.

17. YASCA

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.

26. DeepSource

DeepSource is not fully open source. But, it greatly helps with code review while developing the application. It finds potential security issues and bugs.

27. Joern

You can register a tool using an open-source code analysis tool. It lets you analyze the structure of large code repositories using query formulation. Moreover, it is an excellent tool for searching and removing flaws in C and C++ codes.

28. Sharpen

It’s a framework for analyzing and transforming C# code. It’s a plugin that finds deficiencies in the code. These deficiencies could be potential security weaknesses.

29. CppDepend

CppDepend is a tool to analyze C and C++ code. It monitors project features like the relations between files and design rules. It can find tasks related to code quality analysis.

They add to SAST’s functionality, make apps safe from threats by fitting into the work and development process, cover many programming languages in their basic forms, provide valuable skills in their customized forms, and help make software more secure and resilient.
