Zep

Zep is an end-to-end context engineering platform for AI agents. It addresses the agent context problem by assembling relationship-aware context from chat history, business data, documents, and app events, then delivering the right information at the right time with sub-200ms latency.

Zep ingests messages, business data, and events as they occur. Its Graph RAG layer extracts relationships and maintains a temporal knowledge graph, so context can reflect facts, relationships, and how they have changed over time. It returns pre-formatted context blocks optimized for an LLM.

Zep is offered through Zep Cloud. The legacy Community Edition is deprecated and no longer supported, with its code moved to a legacy folder. Zep is powered by Graphiti, an open-source temporal knowledge graph framework for relationship-aware context retrieval.
