DeepEval vs Giskard
DeepEval and Giskard both help you test LLM and RAG systems, but they come from different directions. DeepEval is LLM-first and developer-centric — it works like pytest for LLM pipelines. Giskard is a broader ML-testing platform (originally for tabular and classical ML) that expanded into LLM scanning and vulnerability detection. Both ship open-source cores with optional managed tiers.
Side-by-side
| Criterion | DeepEval | Giskard |
|---|---|---|
| Primary scope | LLM and RAG evaluation | Broader ML testing + LLM scanning |
| Developer ergonomics | pytest-style assertions | pandas / notebook-first |
| Built-in metrics (RAG) | Faithfulness, answer relevancy, context recall/precision, G-Eval | Similar set via LLM-as-judge |
| Vulnerability scanning | Red-teaming add-on (DeepTeam) | First-class — bias, hallucination, prompt injection |
| License (core) | Apache 2.0 | Apache 2.0 |
| Hosted platform | Confident AI | Giskard Hub |
| CI integration | Strong (GitHub Actions examples, pytest plugin) | Good |
| Best fit | LLM/GenAI teams doing unit-test-style evals | Teams coming from classical ML who added GenAI |
| Community size | Very large in GenAI dev | Large in broader ML |
Verdict
DeepEval is the smoother choice for a pure-LLM team that writes unit tests in pytest — the ergonomics match developer muscle memory, metrics are comprehensive, and the CI integration is strong. Giskard is better when your testing footprint is broader: you also run classical ML, you want a single platform to scan all model types, or your team leans more data-scientist than software-engineer. For red-teaming specifically, Giskard's built-in scanner is more mature out of the box; DeepEval's DeepTeam addon is catching up fast.
When to choose each
Choose DeepEval if…
- Your team writes pytest and wants LLM evals to fit the same mental model.
- You're primarily GenAI / LLM focused — no classical ML.
- You want tight integration with Confident AI for tracking eval history.
- Developer experience is the main driver.
Choose Giskard if…
- Your org runs classical ML alongside GenAI and wants one platform.
- First-class bias / PII / prompt-injection scanning is a must.
- Your team is data-science-first and lives in notebooks.
- You want a single vendor for all ML testing.
Frequently asked questions
Can I use DeepEval with open-source LLMs?
Yes. DeepEval is model-agnostic for the system under test; you configure the judge model separately. You can use local models (via Ollama or an OpenAI-compatible endpoint) for both the target system and the judge.
Does Giskard handle RAG evaluation?
Yes — Giskard has RAGET (RAG Evaluation Toolkit) for RAG-specific metrics and automated red-teaming of RAG pipelines. It's a newer offering than the core tabular / classical features but capable.
Which is better for regression testing in CI?
DeepEval's pytest-style workflow fits naturally in existing CI. Giskard integrates via its Python API in notebook-to-CI pipelines. For pure CI-first LLM testing, DeepEval has less friction.
