Zep Community Edition (legacy)
Deprecated Zep Community Edition provides self-hosted, time-aware agent memory using Docker and separate LLM and embedding services.
Zep Community Edition v1.0.2 is a deprecated, unsupported self-hosted memory service for developers building AI agents and conversational assistants. This legacy edition uses the Apache 2.0 license. It turns chat history into a knowledge graph that records how facts change over time, so an assistant can distinguish a user's current preferences from earlier ones.
Its graph engine, Graphiti, keeps historical context and tracks when facts become valid or stop being valid. Memory can belong to a chat session, a user, or a group, which lets applications retain personal context across conversations or share organizational knowledge. Retrieval combines keyword, semantic, and graph search to find facts relevant to the current conversation. Zep prepares facts and entity summaries in the background rather than using another agent during retrieval.
The server runs through Docker on your own infrastructure, but model processing depends on separate LLM and embedding services. It supports local servers and hosted providers with OpenAI-compatible APIs; Anthropic can connect through LiteLLM. Where conversation data goes therefore depends on the services you connect. Community Edition doesn't include a local embedding service. Zep Cloud is a separate managed offering with additional dialog classification and structured data extraction.
Python and TypeScript SDKs connect the memory service to applications, with integrations including LangChain, LangGraph, and Microsoft Autogen. This edition uses APIs rather than a web UI. It supports deleting user memory, and its optional usage telemetry can be disabled.
