Key Features		• Automated hallucination detection using proprietary ChainPoll methodology • Real-time production monitoring for LLM applications with custom alerting • RAG pipeline evaluation covering both retrieval and generation quality

✓Detectors are 10–100x faster and cheaper than LLM-as-judge for the same task
✓Hallucination detector is purpose-built for RAG and flags unsupported spans, not just a binary score
✓Suitable as an inline guardrail rather than offline-only evaluation

✗Pricing is not public — production buyers must talk to sales before they can budget
✗Narrower scope than full-stack platforms; you still need a tracing or gateway layer alongside
✗Smaller community and fewer integrations than mainstream observability tools — verify SDK coverage for your stack

✓Luna evaluators are dramatically cheaper than LLM-as-judge — eval coverage can stay on in production
✓End-to-end coverage: evals + traces + guardrails + agent root-cause from one vendor
✓Strong enterprise compliance posture (VPC, audit, SSO) suitable for regulated industries

✗No public pricing — every conversation starts with sales, which slows POC adoption
✗Heavier and more opinionated than open-source [/tools/langfuse](/tools/langfuse) or [/tools/arize-phoenix](/tools/arize-phoenix) — early-stage teams may find it overkill
✗Luna evaluators are proprietary — verify quality on your domain before assuming they replace LLM-judge in your stack
