{"slug":"best-sbom-generators-for-container-images","title":"Best SBOM generators for container images","question":"What are the best SBOM generators for container images in 2026?","verdict":"As of 2026-08-10, ChatGPT, Claude, Gemini and Grok collectively rank Syft #1 for sbom generators for container images on ModelsAgree — a unanimous pick. The models' case: Best all-around container specialist: fast local/offline scans, broad OS and language-package detection, Docker/Podman/containerd/registry support, layer controls, and. The models' main caveat: It generates inventory only; vulnerability, policy, and VEX workflows require Grype or another tool. The strongest alternative is Trivy — Near-tie with Syft for practitioners wanting one tool for SBOMs, vulnerabilities, licenses, secrets, and misconfigurations.
