Zep

Zep is a context engineering and agent memory platform that assembles relevant context from chat history, business data, and user interactions for AI agents. It builds a temporal knowledge graph per user that evolves as new facts arrive, automatically extracts entities, and invalidates facts that are superseded. Zep exposes a Graph RAG layer with customizable context blocks for fast personalization. The platform offers Cloud and self-hosted community editions with Python, TypeScript, and Go SDKs and integrations with LangChain, LangGraph, LlamaIndex, CrewAI, and AutoGen. Zep targets sub-200ms p95 retrieval latency and is SOC 2 Type II and HIPAA aligned for enterprise deployments.

Zep publishes 1 API on the APIs.io network. Tagged areas include Memory, AI Agents, Knowledge Graph, Temporal Graph, and Graph RAG.

Zep’s developer surface includes documentation, engineering blog, pricing, and 10 more developer resources.
