Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
One OpenAI-compatible gateway for adaptive LLM routing, guardrails, and spend control
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.
Provides access to a massive catalog of frontier models with flexible routing, but lacks OrcaRouter's dedicated enterprise governance.

Free / Open-sourceOffers an open-source proxy and SDK for unifying 100+ LLMs with failover, requiring self-hosting rather than a managed service.
Routes requests across frontier models with automatic failover and analytics, serving as a straightforward alternative API proxy.

Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
Gives developers a single OpenAI-compatible endpoint for multiple LLMs with failover, but offers fewer advanced routing rules.
Delivers enterprise-grade LLM gateway features with advanced caching and observability, though at a higher operational complexity.
