Comparisons
Head-to-head guides for the most common “which one?” questions.
| Comparison | When to read it |
|---|---|
| RAGAS vs DeepEval | You’re evaluating a RAG product and can’t decide between the two most-mentioned frameworks |
| promptfoo vs inspect_ai | You need red teaming or adversarial testing and aren’t sure whether you need developer-speed or audit-grade output |
| Full matrix | You want all 6 frameworks side-by-side on 10 criteria — setup, cost, CI/CD, EU AI Act, and more |
The short version:
- RAGAS vs DeepEval — not really competitors; most RAG teams use both. RAGAS for retrieval metrics, DeepEval as the CI/CD test runner.
- promptfoo vs inspect_ai — same job, different audiences. promptfoo for developers; inspect_ai for regulators.
- Full matrix — the place to go when you need to explain the framework choice to a stakeholder.
