TL;DR
Static Application Security Testing (SAST) tools help teams catch vulnerabilities earlier in the software development lifecycle, making it easier to fix issues before they reach production. In this guide, we compare nine leading SAST tools based on language support, scan capabilities, integrations, remediation features, usability, and scalability. The right tool depends on your team’s tech stack, workflows, compliance needs, and how deeply you want security embedded into development.
As teams adopt shift-left security and DevSecOps, Static Application Security Testing (SAST) tools help developers identify and fix vulnerabilities early, reducing the risk of insecure code reaching production. Adding static code analysis early in the development process helps cut down on expensive late-stage fixes, supports compliance efforts, and gives teams more confidence as they ship secure software.
Below, we’ve gathered nine leading SAST tools worth considering. Each includes details on language support, scan capabilities, integrations, remediation features, usability, and scalability. Whether you are securing a small application or a complex enterprise codebase, this guide can help you find the best fit for your technology stack, workflows, and security goals.

GitLab includes built-in SAST as part of its DevSecOps platform, making it especially attractive for teams already standardized on GitLab. Current GitLab docs show full support for languages such as C/C++, C#, Go, Java, JavaScript, PHP, Python, Ruby, TypeScript, and YAML, with additional language coverage through standard analyzers. GitLab Advanced SAST uses cross-function and cross-file taint analysis, and diff-based scanning can limit analysis to merge request changes so developers can focus on new risk sooner.
Good for: Teams already using GitLab CI/CD that want security findings surfaced directly in native pipeline and merge request workflows.

Snyk Code extends the Snyk platform into static analysis, complementing SCA, container, and infrastructure security. Snyk supports a broad range of modern languages, provides real-time in-line results in IDEs and pull requests, and promotes automatic, build-free scanning with a developer-friendly remediation context. Snyk’s AI-assisted fix workflow can generate multiple suggested fixes and retest them using Snyk Code’s engine, which helps developers remediate issues without leaving their workflow.
Good for: Teams already invested in Snyk or teams that want static analysis as part of a wider developer security platform.

A SAST tool analyzes source code, bytecode, or binaries to identify security vulnerabilities without running the application. It helps teams catch issues early in development before code moves further down the pipeline.
SAST supports DevSecOps by helping teams detect and fix vulnerabilities earlier, when remediation is typically faster, less expensive, and less disruptive. It also helps developers build security into their daily workflows instead of treating it as a separate step at the end.
The most important factors usually include language support, scan speed, CI/CD and IDE integrations, remediation guidance, deployment flexibility, reporting, and support for compliance or security standards relevant to your organization.
Some SAST tools do a better job than others at prioritizing findings, reducing noise, and helping teams focus on real risk. Features like contextual analysis, customizable policies, and remediation guidance can make results more actionable.
SAST analyzes code before an application runs, while Dynamic Application Security Testing (DAST) tests a running application from the outside. SAST is useful for catching issues earlier in development, while DAST helps identify vulnerabilities that appear in live or deployed environments.
SAST is an important part of application security, but it works best alongside other approaches such as DAST, software composition analysis (SCA), infrastructure security checks, and secure development practices.
The best choice depends on your environment, but many growing teams look for a tool that balances broad language support, actionable remediation guidance, CI/CD integrations, and deployment flexibility. For teams that want to embed secure coding practices into development without adding unnecessary friction, Kiuwan is a strong option to consider.
