giskard-oss
Giskard is an open-source Python library for testing and evaluating AI agents and LLM-based systems. It provides tools for creating evals (tests that validate non-deterministic outputs), red-teaming agents for vulnerabilities, and generating synthetic evaluation datasets—all with minimal dependencies and async-first architecture.

What giskard-oss is
Giskard v3 is a modular, lightweight Python library built on giskard-core that wraps LLMs, black-box agents, and multi-step pipelines. It offers scenario-based testing with built-in checks (Groundedness, Conformity, LLMJudge), an automated vulnerability scanner (Scan), and planned RAG evaluation capabilities. Python 3.12+ required; includes optional telemetry.

Best use cases
Implementation considerations
- Giskard v3 is in Beta (Checks and Scan). RAG evaluation is still in v2 and planned for v3; confirm feature availability before committing to evaluation pipelines that depend on RAGET.
- LLMJudge checks require LLM API access (OpenAI, etc.). Budget for inference costs and latency in evaluation runs; async-first architecture helps parallelize multi-scenario tests.
- Telemetry is optional but enabled by default. Configure opt-out in giskard-core if data residency or air-gapped requirements exist.
- Scenario API is async-first (uses asyncio). Wrap with asyncio.run() in scripts or integrate into async event loops in production frameworks.
- Custom checks and scenario generators require Python knowledge. Simple string/regex checks are straightforward; LLM-as-judge checks need prompt engineering and model selection.
When to avoid it — and what to weigh
- Deterministic Model Testing — Giskard is designed for non-deterministic systems. If you need strict unit testing for classical ML or rule-based systems, use pytest or unittest instead.
- Real-Time Production Monitoring — Giskard is a testing and evaluation library, not a production monitoring framework. Use it in CI/CD pipelines or batch evaluation workflows, not for inline request validation.
- Offline-Only Environments — Giskard includes optional telemetry and may require external API calls (for LLM-as-judge checks). If you need fully air-gapped operation, review telemetry settings and LLMJudge dependencies.
- Low Python Version Support — Requires Python 3.12+. Do not use if your infrastructure is locked to Python 3.10 or earlier.

Giskard itself is a testing tool, not a security product. It helps identify vulnerabilities (e.g., prompt injection, data leakage) in your agents through red-teaming. No security audit details provided in source data. LLMJudge checks depend on external LLM services; ensure your prompts and test data do not leak sensitive information through API calls. Optional telemetry should be reviewed per your compliance requirements.
Alternatives to consider
Promptfoo
Also tests LLM chains and agents with scenario-based checks. Lighter weight, but lacks built-in red-teaming (Scan) and focused on prompt optimization rather than vulnerability detection.
LangSmith (LangChain)
Provides evaluation, tracing, and monitoring for LLM applications. Tighter integration with LangChain; requires vendor lock-in. Better for production observability; weaker at automated red-teaming.
Arize AI (ModelOps)
Enterprise-grade ML monitoring with LLM-specific features. Heavier, requires infrastructure. Better for production monitoring; Giskard is better for pre-deployment testing and red-teaming.
