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.","theCatch":"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.","addedAt":"2026-10-18","featured":false,"domain":"AI Agents","subSpecialty":"Agents","subcategory":"Evals & Tracing","tags":["self-host","permissive","coding-agents","evals","security","observability","active"],"capabilities":[],"surfaces":["Self-host"],"ecosystem":["Multi-platform"],"licenseModel":"Apache-2.0","githubStars":2858,"starsPerWeek":20,"access":"free","archived":false,"repo":{"createdAt":"2024-01-23","pushedAt":"2026-10-15","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/openlit","html":"/gems/openlit","markdown":"/gems/openlit.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
