Description
21st is a development platform designed to help engineers quickly build and deploy AI agents inside their applications. The platform provides a specialized SDK that simplifies the process of defining agent behavior, integrating tools, and connecting AI models. Developers can create agents using familiar technologies such as Next.js, React, TypeScript, Python, and Node.js, making integration straightforward for modern applications. Once an agent is defined, the platform allows it to be deployed with a single command while automatically handling infrastructure requirements. 21st provides sandboxed execution environments through E2B sessions, ensuring that agent operations run securely and independently. The platform includes a ready-to-use chat interface component that can be embedded directly into an app for user interaction. Additional features include token streaming, conversation history, tool execution, and built-in observability for debugging and monitoring. Developers can replay sessions and trace tool calls to better understand how agents behave during execution. The system also supports spend limits, authentication controls, and rate limiting to manage AI usage across users. By combining development tools with managed infrastructure, 21st helps teams launch scalable AI agents without building complex backend systems.
Description
ZizkaDB is an operational intelligence platform for AI agents that helps teams debug, monitor, and understand production behavior. The system is designed to go beyond basic logs by storing agent decisions, causal lineage, time-travel state, session replay, semantic history, and drift signals. ZizkaDB helps teams see why an agent made a decision, what changed after a prompt or deployment update, and where behavior diverged from an expected baseline. Developers can replay any session end to end, trace the decision chain, identify root causes, and roll back or fix regressions more quickly. The platform supports Python, TypeScript, MCP, REST API, Docker-based self-hosting, and managed cloud deployment. Its dashboards include Activity, Behavior, Reports, Suggestions, and Fleet features for managed cloud and enterprise users. Security and trust features include open source AGPL licensing, self-hosting, checksum-backed events, and single-tenant VPC deployment options. Pricing includes a free self-hosted plan, Pro and Team cloud plans, and enterprise licensing for private deployments. By combining replay, lineage, drift detection, behavioral baselines, cross-agent visibility, and flexible deployment, ZizkaDB helps teams fix agent behavior before production breaks.
