Is Trivy or Weka better?

Neither clearly leads. Trivy starts at Free and Weka at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Trivy or Weka?

Trivy starts at Free and Weka at Free.

Does Trivy or Weka run on more platforms?

Trivy runs on Linux, macOS, Windows, Docker, Kubernetes. Weka runs on Linux, Mac, Windows.

Can I use Trivy for free?

Both have a free tier, so you can try either at no cost before committing.

What is Trivy best used for?

Trivy is most often used for failing a pull request when a container image introduces a known cve, scanning terraform and kubernetes manifests for misconfiguration before apply, catching committed secrets as part of an existing ci step. Of those, failing a pull request when a container image introduces a known cve and scanning terraform and kubernetes manifests for misconfiguration before apply are not what Weka is typically brought in for.

What can Trivy do that Weka cannot?

Trivy covers Multi-target scanning, Vulnerability detection, Misconfiguration checks, Secret detection. Weka covers Classification, Regression, Clustering, Association rules.

The short version

Each has a real cost: Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise; Weka the package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
They diverge on capability: Trivy covers Multi-target scanning, Weka covers Classification.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Trivy

Reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
No built-in triage or exception workflow, so suppressing accepted risk is managed in config files
Findings are point-in-time from CI, with no continuous runtime monitoring unless you add the commercial platform

Weka

The package management system needs an internet connection to download and install packages, so an air-gapped install gets only the core distribution
Weka is split into a stable 3.8 branch that receives only bug fixes and compatibility-safe upgrades and a 3.9 development branch that may receive features that break compatibility
Weka requires a 64-bit Java VM; the bundled installers ship Bellsoft OpenJDK 25 per platform and architecture
