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
