Cerebro vs Zep
Zep is a memory and context engine for AI assistants. Cerebro goes beyond memory — it's a cognitive organism with reasoning, prediction, and learning, running entirely on your hardware.
Zep: Zep provides long-term memory and context enrichment for LLM-powered assistants and agents. It offers session management, entity extraction, and temporal context with both cloud and self-hosted options.

Key Differentiators
Cognitive, Not Just Contextual
Zep enriches context. Cerebro thinks — it reasons about cause and effect, predicts problems, and learns from mistakes. Context is just one of 49 capabilities.
Truly Private
Cerebro never phones home. Zep's cloud offering processes your data on their infrastructure. Even Zep's self-hosted version requires their managed services for key features.
Causal Chains & Prediction
Cerebro builds causal models of your workflow and predicts failures before they happen. Zep stores temporal context but doesn't reason about causality.
Free & Open Source
All 49 tools, free forever. Zep's most valuable features — fact extraction, structured data output — require their paid cloud tier.
Why Choose Cerebro
- Goes beyond context enrichment — full reasoning, prediction, and self-improvement
- 49 tools across 10 categories vs Zep's focused memory and context features
- Completely local. No cloud dependency for any feature
- Free and open-source — no paid tier required for advanced capabilities
- MCP-native: works with Claude Code, Cursor, Windsurf out of the box
- Active learning system that improves from corrections and reinforcement
Frequently Asked Questions
Both handle session continuity, but Cerebro's approach is broader. Cerebro offers session handoff, working memory management, continuation detection, and active work tracking — plus it preserves reasoning context, not just conversation history.
Both install in minutes. Cerebro installs via pip (pip install cerebro-ai) and requires only a Python 3.10+ environment. Zep's cloud tier is instant but requires account creation and API keys. Zep's self-hosted option needs Docker and additional configuration.
Yes. Cerebro covers all of Zep's memory and context features through its MCP tools, and adds causal reasoning, predictive intelligence, learning, personality modeling, and more. It integrates via the Model Context Protocol, compatible with any MCP-enabled client.
