<CardGroup cols={2}> <Card title="Trace my LLM calls" href="/tracing/getting-started" icon="fa-solid fa-eye" iconPosition="left"> See every LLM call, tool invocation, and span in real time. Debug failures, track token costs, and understand exactly what your agent is doing at every step. </Card> <Card title="Evaluate my agent's quality" href="/evaluation/getting-started" icon="fa-solid fa-chart-line" iconPosition="left"> Run automated evaluations with LLM-as-a-judge and 30+ pre-built metrics. Build test suites from real production failures and catch regressions before they ship. </Card> <Card title="Optimize my prompts automatically" href="/optimization-runs/quickstart" icon="fa-solid fa-brain" iconPosition="left"> Use six optimization algorithms to auto-generate and score better prompts for every step of your agentic system — no manual tuning required. </Card> <Card title="Run Opik on my own infrastructure" href="/self-host/overview" icon="fa-solid fa-server" iconPosition="left"> Deploy with Docker locally or Kubernetes at scale. Full control over your data with no cloud dependency. </Card> </CardGroup>
