Zep

Zep is an open-source memory platform for AI agents and LLM applications that provides long-term memory, conversation storage, semantic search, and contextual knowledge retrieval. It helps AI systems remember user interactions, store embeddings, manage conversation histories, and retrieve relevant information across sessions. This pre-configured Ubuntu 26.04 LTS environment includes Zep, PostgreSQL, Neo4j, and Graphiti for building intelligent, memory-enabled AI applications and agent workflows.

Features of Zep:

• Provides long-term memory capabilities for AI agents and LLM-powered applications.
• Stores and manages conversation histories, user context, and knowledge data.
• Supports semantic search and retrieval of relevant memories using vector embeddings.
• Integrates with PostgreSQL for data storage and management.
• Uses Neo4j and Graphiti for knowledge graph and relationship-based memory retrieval.
• Enables persistent memory beyond the context window limitations of large language models.
• Offers REST APIs for integrating memory services into AI applications and workflows.
• Supports self-hosted deployments for enhanced security, privacy, and control.
• Designed for use with AI agents, chatbots, virtual assistants, and autonomous systems.
• Includes Zep, PostgreSQL, Neo4j, and Graphiti on Ubuntu 26.04 LTS.

Zep usage:

$ sudo su
$ cd /opt/zep/legacy

# Start Docker services
$ docker compose -f docker-compose.ce.yaml up -d

# Check service status
$ docker compose -f docker-compose.ce.yaml ps

# Check Zep health endpoint
$ curl -i http://localhost:8000/healthz

# Check Graphiti health endpoint
$ curl -i http://localhost:8003/healthcheck

# Check logs if any service fails
$ docker compose -f docker-compose.ce.yaml logs --tail=100
