Use case
Install a pinned release in an isolated environment, obtain authorization for every target, select appropriate probes and generators, control cost and rate limits, protect test data, review results manually, and disclose findings through approved security processes rather than treating scores as complete assurance.
Trace model calls, compare prompt versions, run evaluations, monitor costs, and investigate production behavior.
Pros
  • Free under Apache-2.0
  • Broad model-provider support
  • Maintained with NVIDIA contribution
  • Open-source self-hosting option
  • Covers prompts, traces, and evaluations
  • Useful development and production workflow
Limitations
  • garak does not prove that a model or application is secure. Coverage depends on selected probes, model settings, target permissions, and detector quality. Users must obtain authorization, prevent harmful output exposure, control costs, and combine scanning with broader threat modeling and review.
  • Lunary organizes observability and evaluation, but teams still need representative datasets, valid metrics, privacy controls, model access, and application-level testing. Important outputs should receive qualified human review before operational use.

Garak vs Lunary Comparison

This page compares Garak and Lunary using verified profile fields from AstronovAI, including use case, pricing model, trial status, strengths, limitations, ratings, and score signals.

Both tools share a similar category context, so the comparison focuses on practical differences in positioning, feature fit, and adoption criteria.

Comparison Methodology

AstronovAI compares tools using verified profile fields such as category, primary use case, pricing model, trial status, ratings, pros, limitations, and editorial review status.

Pricing

We show the listed pricing model and avoid treating unknown fields as confirmed offers.

Use Case Fit

We compare the main use case and target context of each tool before assigning any recommendation.

Profile Quality

Tools must pass content verification checks before they appear in public comparisons.

Score Signal

Scores are treated as one signal, not as a replacement for feature and use-case review.

Ranking independence

Paid or Featured placement does not improve organic comparison ranking, and verification is shown as a trust fact rather than an approval or ranking bonus.

Editorial takeaway

Which tool is the better fit?

No universal winner — choose by use case

The score signals are close or the tools serve different workflows, so this comparison is designed to match each product to the right job instead of forcing a single winner.

Garak Security and, AI teams testing language-model failure modes in controlled environme…, and AI security engineers
Lunary AI engineers and developers building production model applications, AI engineers, and ML engineers

Review pricing, trial status, use cases, strengths, limitations, and profile details before choosing, especially when the tools serve different workflows.
