LunaTrace is a free software composition analysis tool. Safety CLI is a free software composition analysis tool by Safety. Compare features, ratings, integrations, and community reviews side by side to find the best software composition analysis fit for your security stack.
Based on our analysis of core features, here is our conclusion:
Teams managing open source dependencies in GitHub repositories should pick LunaTrace because it catches vulnerable libraries before code reaches production and costs nothing to deploy. The tool integrates directly into GitHub workflows, removing the friction of bolting security onto an existing pipeline; 1,468 GitHub stars reflects genuine adoption among developers who actually use it. Skip this if you need scanning across multiple VCS platforms or dependency management for languages outside the JavaScript and Python ecosystems where LunaTrace has the strongest coverage.
Python-focused development teams running CI/CD pipelines need Safety CLI for its expert-verified fix recommendations that actually specify version upgrade paths, not just vulnerability listings. The tool scans across local, CI/CD, and production environments with policy-based configuration, and its proprietary database catches vulnerabilities that public feeds miss. Skip this if your codebase is polyglot and you need to scan Java, JavaScript, and Go dependencies equally; Safety CLI's strength is Python specificity, which becomes a weakness the moment you need language coverage.
