Promptfoo Code Scanning / GitHub Action vs SOOS SAST: Side-by-Side Comparison (2026)

Short answer

Development teams shipping LLM applications into production need Promptfoo Code Scanning because it catches prompt injection and indirect prompt injection attacks that static SAST tools simply don't know how to look for. The GitHub Action integrates directly into CI/CD without requiring separate infrastructure, making it free to run on every pull request across your entire codebase. Skip this if your LLM usage is limited to off-the-shelf chatbots with no custom prompts or agentic logic; the signal-to-noise ratio drops sharply when you're not actually building LLM features. Teams running multiple SAST tools or SonarQube instances will value SOOS SAST for consolidating findings into a single dashboard without ripping out existing scanners. The platform ingests SARIF results from any external SAST tool and adds its own Semgrep and Gitleaks scans, letting you see everything in one place while preserving your current toolchain. Skip this if you need deep language-specific vulnerability analysis; SOOS is an aggregation layer, not a replacement for specialized scanners like Checkmarx or Fortify.
