Opsin is a commercial ai spm tool by Opsin. Promptfoo Code Scanning / GitHub Action is a free ai spm tool by Promptfoo. Compare features, ratings, integrations, and community reviews side by side to find the best ai spm fit for your security stack.
CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
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.
