What is ZizkaDB?

ZizkaDB by Zizka AI is an operational database and intelligence layer built for teams running AI agents in production. The platform helps teams understand why an agent did what it did by capturing agent decisions, causal lineage, replayable sessions, behavioral baselines, and drift alerts. ZizkaDB is designed for situations where production agents change behavior after prompt tweaks, skip tool policies, answer the same question differently, or produce failures that ordinary logs cannot explain. With ZizkaDB, teams can replay a full session, inspect the decision trail, identify the exact source of behavior change, and confirm when a baseline has been restored. The platform supports event logging from Python, TypeScript, MCP, and REST, with one API key per agent and no heavy infrastructure project required. Teams can run ZizkaDB as an open source AGPL stack with Docker Compose or use the managed cloud version. The self-hosted version includes Activity, Behavior, Reports, and Suggestions, while managed cloud adds Fleet ranking across agents and projects. ZizkaDB also supports semantic search on history, time travel, cross-agent fleet queries, and checksum-backed events for tamper-evident decision history. Enterprise options include single-tenant VPC deployment, up to 50 agents, a Fleet dashboard, integration workshops, and dedicated support. The platform positions itself between traces, memory systems, and vector databases by focusing specifically on agent decisions, lineage, behavioral drift, and operational debugging. By combining production replay, causal lineage, drift alerts, behavioral reporting, self-hosting, managed cloud, SDKs, MCP support, and enterprise deployment, ZizkaDB helps AI teams stop debugging agents in the dark.

What is 21st?

21st is a developer-focused platform designed to simplify the creation and deployment of AI agents within modern software applications. The platform provides an SDK that allows developers to define agents using simple code while integrating tools, prompts, and AI models. It supports multiple development environments and frameworks including Next.js, React, TypeScript, Python, Node.js, and other common programming stacks. Developers can configure agents to run on advanced runtimes such as Claude Code or Codex, enabling tool usage, file access, and intelligent task execution. Once the agent configuration is defined, deployment can be completed using a single command that automatically sets up infrastructure. The platform manages backend systems such as sandboxed execution environments, authentication, rate limits, and streaming responses. It also includes a drop-in chat interface component that developers can embed directly into their applications to enable user interaction with agents. Real-time token streaming allows users to see responses generated progressively, creating a more interactive experience. The platform provides built-in observability tools that allow developers to monitor conversations, replay sessions, and trace agent actions. These features make debugging and optimization much easier during development and production. 21st also includes usage controls such as per-user spending limits, quotas, and metering to help manage AI costs. By combining powerful developer tools with managed infrastructure and deployment capabilities, 21st makes it easier for teams to build and scale AI-powered agents within their products.
