Open-source, OpenTelemetry-native observability and harness engineering for AI agents
Capture OpenTelemetry traces and metrics for every LLM call, tool invocation, retrieval, and agent step, and filter them by user, session, cost, latency, or custom metadata.
Score production traffic or experiments with LLM-as-a-judge, heuristic checks, or human review so you can measure accuracy, relevance, and safety over time.
Manage and version prompts in Prompt Hub, then deploy, roll back, and update prompts without shipping new application code.
Store and rotate OpenAI, Anthropic, and other LLM API keys outside your codebase with an encrypted, rotating secrets vault.
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.

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.
