Apache-2.0 OTel tracing, evals and guardrails for agents

What's Good

Apache-2.0 (openlit/openlit), free to self-host. Integrations cover Claude Code, Codex, Cursor, the OpenAI Agents SDK, LangGraph, CrewAI and 70+ more, with OpenTelemetry-native output you can send to your own backend. Includes an OTel GPU collector for model-serving hardware. ★~2.9k.

The Catch

The README is heavy on the new agent-harness-engineering framing; underneath it is an OTel tracing and eval platform in a crowded field. Self-hosting means running its UI and ClickHouse. Many repos and releases (SDKs, collectors) to keep in sync.

Verdict

A solid self-hosted LLM observability option, especially if you also watch GPU cost.
