Compare the Top Free Static Application Security Testing (SAST) Software as of June 2025

What is Free Static Application Security Testing (SAST) Software?

Static Application Security Testing (SAST) software analyzes the source code, binaries, or bytecode of an application to identify vulnerabilities before the code is run in production. This type of software scans the application at rest to detect issues such as coding errors, security flaws, and weaknesses like SQL injection, cross-site scripting (XSS), and buffer overflows. SAST tools provide developers with early insights into potential security vulnerabilities, allowing them to fix issues before deployment. These tools are typically integrated into the software development lifecycle (SDLC), supporting secure coding practices and helping teams build more secure applications. Compare and read user reviews of the best Free Static Application Security Testing (SAST) software currently available using the table below. This list is updated regularly.

    Contrast Security

    Contrast Security

    Contrast Security

    Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.

    Brakeman

    Brakeman

    Brakeman

    Brakeman is a security scanner for Ruby on Rails applications. Unlike many web security scanners, Brakeman looks at the source code of your application. This means you do not need to set up your whole application stack to use it. Once Brakeman scans the application code, it produces a report of all security issues it has found. Brakeman requires zero setup or configuration once it is installed. Just run it. Because all Brakeman needs is source code, Brakeman can be run at any stage of development: you can generate a new application with rails new and immediately check it with Brakeman. Since Brakeman does not rely on spidering sites to determine all their pages, it can provide more complete coverage of an application. This includes pages which may not be ‘live’ yet. In theory, Brakeman can find security vulnerabilities before they become exploitable. Brakeman is specifically built for Ruby on Rails applications, so it can easily check configuration settings for best practices.
