njsscan review
A free, CI-ready Node.js SAST scanner with flexible reporting and rule controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
njsscan is an open-source static application security testing tool for Node.js applications. It scans source files or directories from the command line, combining pattern matching with syntax-aware semantic analysis to detect insecure code patterns. It is suited to Node.js teams that want a free scanner they can place in CI/CD workflows, run locally, or execute through Docker without moving source analysis to a hosted platform.
Its strongest area is pipeline fit and output flexibility. njsscan integrates with GitHub Actions, GitHub Code Scanning, GitLab CI/CD, Travis CI, and CircleCI, while its Docker image supports container-based execution. Findings can be exported as JSON, SARIF, HTML, SonarQube, DefectDojo, or GitLab SAST reports, giving teams several ways to feed results into existing security and development workflows. Configurable rules, ignored paths, severity filters, severity overrides, and inline suppression help teams adjust scanning behavior. A Python API is also available for programmatic use.
The pricing model is open source with a free plan, making njsscan a clear fit for teams seeking Node.js coverage without paid tiers. Its focus is also its main boundary: the verified analysis target is Node.js source code, so teams with broader language requirements should look elsewhere. The product does not provide IDE support or fix guidance, which may limit its usefulness for developers who want findings surfaced during editing or accompanied by remediation direction. Choose njsscan for configurable, CI-integrated Node.js scanning and multiple report formats; choose another SAST option when broader language coverage, IDE workflows, or fix guidance are priorities.
