The honest brief

Helicone

Fastest setup in the category: change one base URL, no SDK, and the open-source proxy can be self-hosted.

  • No SDK or code changes to integrate
  • Open source, self-hostable
  • Built-in caching and rate-limit handling
  • Multi-provider gateway
  • Request/response focused, not span-based
  • Weaker multi-step agent tracing
  • Proxy adds a network hop
  • Lighter eval tooling than Langfuse

Opik

Fully self-hostable, pairing call tracing with built-in LLM-as-judge evals — own the stack or use Comet cloud.

  • Self-host via Docker/Kubernetes
  • Tracing plus evals in one tool
  • Prompt management and dashboards
  • Framework-agnostic integrations
  • Younger than some rivals
  • Hosted tier tied to Comet
  • Self-host needs ops effort
  • Smaller ecosystem than LangSmith
