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graph per user that evolves as new facts arrive, automatically extracts entities, and invalidates facts that are superseded.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 9 more developer resources.
