    • Agent Simulation & Evaluation — Run single and comparison agent simulations, evaluate voice agents, and schedule automated runs to catch regressions.
    • Evaluator Store — Access Maxim's built-in evaluators or create custom ones; supports human evaluation workflows and managed human evaluation on Enterprise.
    • Production Observability — Capture logs and traces from production, apply advanced filtering, and run online evaluations on live data.
    • Dataset Management — Create datasets from production logs, manage entries, and use them to drive evaluation pipelines.
    • CI/CD Integrations — Plug evaluations into existing CI/CD pipelines to enforce quality gates before deployment.
    • Custom Dashboards & Reports — Build live dashboards and comparison reports to track model and agent performance over time.
    • PII Management & RBAC — Protect sensitive data in logs and control access with role-based permissions.
    • Broad Framework Integrations — Connect via SDK to LangChain, LangGraph, OpenAI, CrewAI, LiteLLM, Anthropic, Bedrock, Mistral, LiveKit, and more.
