  • Get started: install (PyPI, release binaries, charts) and run your first evaluation in a minute.
  • Changelog: what changed in each release.
  • Examples: runnable configs for runs, agents, guardrails, fine-tuning and more.
  • Agent frameworks: score LangGraph, CrewAI, OpenAI Agents SDK, LlamaIndex and Claude Agent SDK traces.
  • Trace sources: score the traces you already keep in MLflow, Phoenix or Langfuse.
  • Operations: upgrade policy, backup and restore, runbooks and reference cluster values.
