Galileo - Pros & Cons

Pros

  • ✓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

Cons

  • ✗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

Helicone - Pros & Cons

Pros

  • ✓5-minute proxy integration captures full traces, cost, and latency across 20+ providers
  • ✓Real AI gateway features (caching, retries, fallback, key vault) replace a custom proxy
  • ✓MIT-licensed and self-hostable on Postgres + ClickHouse — passes regulated procurement

Cons

  • ✗Proxy mode adds a network hop unless self-hosted in your own region
  • ✗Prompt experiment UX is less mature than dedicated eval platforms like Braintrust
  • ✗Self-hosting requires running ClickHouse, which is an extra ops surface
