giskard-oss vs ragas
Python toolkits for evaluating LLM applications compared
giskard-oss and ragas are Apache-2.0 Python toolkits for evaluating LLM-powered systems. giskard-oss focuses on agent behavior, multi-turn testing, and adversarial security checks, while ragas emphasizes evaluation metrics, generated test data, and feedback from production data.
giskard-oss: Test and Red-Team LLM Agents
Giskard is a Python toolkit for evaluating agent behavior and probing AI systems for vulnerabilities. It suits teams building LLM agents or RAG applications that need repeatable checks, safety testing, and adversarial evaluation.
ragas: Evaluate and Improve LLM Applications
Ragas is a Python toolkit for evaluating and improving LLM applications with metrics, generated test data, and feedback from production data. It suits teams building evaluation workflows for retrieval-augmented generation and other LLM-powered systems.

Key differences
- giskard-oss supports scenario-based checks for synchronous or asynchronous targets and multi-turn agent interactions; ragas provides metrics and custom evaluations for application outputs.
- giskard-oss generates adversarial tests for issues such as prompt injection and harmful content; ragas generates test datasets and supports feedback loops using production data.
- giskard-oss includes checks for RAG answer grounding and agent security; ragas focuses on scoring application quality with LLM-based and traditional metrics.
- The current giskard-oss v3 release requires Python 3.12 or later; ragas is described as a Python toolkit without a version requirement in the supplied data.
- Both projects use the Apache-2.0 license; giskard-oss has 5.9k stars and 547 forks, while ragas has 15.9k stars and 1.7k forks.
Choose giskard-oss if you…
- need to evaluate multi-turn agents or complete conversations.
