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
