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

Laminar

Agent-first tracing in one line of code, with an evals SDK in the same stack — not a general LLM logger bolted onto agents.

  • Self-hostable, Apache-2.0 licensed
  • OpenTelemetry-native, vendor-portable
  • Built for long-running agents
  • Tracing + evals in one platform
  • Younger than LangSmith/Langfuse
  • Smaller ecosystem and integrations
  • Self-host adds infra overhead
