Snyk Container alternatives for Kubernetes vulnerability scanning

Teams look for a Snyk Container alternative when they discover that seeing their Kubernetes clusters needs the Enterprise plan, or when per-developer pricing stops making sense for a platform team whose problem is running workloads rather than repositories.

What Snyk Container does well

Before the list: Snyk Container is a good tool for the right team. Snyk Container is the container-scanning product in Snyk’s developer security platform, scanning images from the CLI, CI and registries and opening automated base-image upgrade pull requests.

  • Best-in-class developer workflow: IDE, CLI and CI integrations, plus automated base-image upgrade PRs.
  • A Risk Score that blends CVSS, EPSS, exploit maturity and reachability signals.
  • One platform for code, open-source dependencies, containers and IaC.
  • Published pricing for the Free and Team plans.

Snyk Container pricing

Snyk publishes its Free plan (100 container tests per month) and Team plan (from $25 per contributing developer per month). Kubernetes integration — importing workloads from a running cluster — requires the Enterprise plan, which is quote-based. A platform team of ten on Team is $250 per month before any cluster visibility.

Snyk Container alternatives

1. StackRadar (that's us)

StackRadar keeps a CycloneDX SBOM for every image running in your Kubernetes clusters and re-checks it against OSV.dev advisories as they land — no rescan. Findings are ranked by the Radar Score, which combines CVSS, EPSS and the CISA KEV catalogue in a published formula, and every finding carries its workload, Helm release and ArgoCD application. One dashboard covers every cluster, with 30 days to two years of history by plan. The scanner installs as one Helm chart, its source is published, releases are signed, and data stays in the EU. Free for one cluster; Pro $59 per month; Business $199 per month.

Where Snyk Container is stronger: your priority is shifting left: fixing images in the pipeline before they ship. See StackRadar vs Snyk Container for the full comparison.

2. Docker Scout

Docker Scout is Docker’s image analysis service: layer-level SBOMs, vulnerability matching against many advisory sources, and base-image recommendations, integrated into Docker Desktop and Docker Hub.

Best for: You want vulnerability feedback at build time, in Docker Desktop and CI. Pricing: Free (1 repo); unlimited with Docker Team $15/user/mo. Compare with StackRadar · Docker Scout website

3. Trivy Operator

Trivy Operator is the free, Apache-2.0 Kubernetes operator from Aqua Security that scans running workloads with Trivy and writes the results into the cluster as custom resources.

Best for: You run one or two clusters and mainly want to know what is vulnerable right now. Pricing: Free (Apache-2.0); you run and operate it. Compare with StackRadar · Trivy Operator website

4. Anchore Enterprise

Anchore Enterprise is an SBOM-centric SCA platform from the maintainers of Syft and Grype, focused on compliance-driven scanning of images in registries and CI, with an Anchore Score built from CVSS, EPSS and CISA KEV.

Best for: You need SBOM management for a compliance programme (FedRAMP, DoD, medical devices) more than cluster visibility. Pricing: Quote-only. Compare with StackRadar · Anchore Enterprise website

Should you switch?

Choose Snyk Container if

  • Your priority is shifting left: fixing images in the pipeline before they ship.
  • You want automated base-image upgrade pull requests in your repositories.
  • You already use Snyk for code and dependency scanning and want one platform.
  • You are on Enterprise and its Kubernetes import already covers your clusters.

Choose StackRadar if

  • You need to know what is running in the cluster, not what was scanned in CI.
  • You do not want Kubernetes visibility gated behind an enterprise contract.
  • You would rather pay per cluster than per developer.
  • You want KEV-listed findings surfaced first and every advisory openly linked.

Frequently asked questions

Does Snyk scan Kubernetes clusters?

Snyk can import workloads from Kubernetes clusters, but that integration is limited to the Enterprise plan. On Free and Team, Snyk Container scans images from the CLI, CI pipelines and registries.

Is Snyk Container free?

The Free plan includes 100 container tests per month. Paid plans start at $25 per contributing developer per month on Team; Kubernetes integration requires Enterprise.

Can I use Snyk and StackRadar together?

Yes, and it is a sensible split: Snyk in the pipeline to fix images before they ship, StackRadar in the cluster to track what is actually running and to re-check stored SBOMs as new advisories land.
