Best for Teams that want ready-made, scored evaluators for safety and accuracy risks rather than building custom scoring from scratch. Engineering teams that want LLM evaluation as unit-test-style code in CI/CD, with an optional hosted layer for production evals. Teams evaluating RAG pipelines specifically, who want reference-free metrics without hand-labeled ground truth. Teams that want real-time guardrails intervening on production traffic, not just after-the-fact dashboards. Teams that want evaluation and experimentation as the primary workflow, with production monitoring layered on top.
