Dont Observe – Audit Your AI Agent

ZizkaDB launched a monitoring platform that stores causal lineage and time-travel state for AI agents, positioning itself against Laminar, LangSmith, Langfuse, and Arize Phoenix. The company claims its product is the only one of the five to offer causal lineage, time travel over logged state, native drift baselines, free self-hosting under AGPL, and first-party EU AI Act mapping, scoring itself 5/5 versus 2 for Laminar, 2 for LangSmith, 1–2 for Langfuse, and 2 for Arize Phoenix. ZizkaDB logs from Python, TypeScript, LangChain, CrewAI, LiveKit voice agents, MCP, and REST, and is available via Docker Compose self-hosting or a managed cloud with single-tenant VPC deployment.

Two ways to run ZizkaDB Explore the dashboard your team gets — self-host the OSS stack or use managed cloud with Fleet. Docker Compose on your infra. Activity, Behavior, Reports, and Suggestions out of the box. Why ZizkaDB Production agents need operational data — not just logs. ZizkaDB monitors behavior so your team can correct it. Same incident. Without ZizkaDB you guess. With it you see the exact decision trail. For teams building with agents Log from Python, TypeScript, LiveKit voice agents, MCP, or REST. One API key per agent — no heavy infra project. Python SDK, TypeScript SDK, LangChain, CrewAI, LiveKit voice, MCP, or REST. Self-host with Docker or use managed cloud. Prompt change broke behavior? Replay the full session, trace the decision chain, find root cause. Single-tenant VPC deployment with Fleet dashboard, workshops, and dedicated support. Trust and security Pricing Full monitoring and session replay on every plan. Compare Laminar, LangSmith, Langfuse, and Phoenix trace spans.
