Long-term memory for AI agents.

Visit official site →

About

Zep (getzep/zep, Apache-2.0, ~5k stars) is the long-term memory layer for agents: temporal knowledge graphs that let agents remember facts, entities, and conversations across sessions.

Clean record, actively maintained. The memory upgrade when 'the agent forgot what we discussed' becomes a real problem.

What it can do

  • Temporal knowledge graph
  • Long-term agent memory
  • SDKs
  • Self-host or cloud
  • Apache-2.0

Setup

  1. Self-host via Docker or use Zep Cloud.
  2. Connect via the SDK.
  3. Add facts/episodes as the agent works.
  4. Query memory in context.

Prerequisites

Docker (self-host) or Zep Cloud account.

Use cases

Works with
