Open-source memory layer for AI agents combining graph, vector, and relational storage with flexible deployment from self-hosted to managed cloud.

Pros

• Hybrid storage architecture (graph + vector + relational) for richer context
• flexible deployment options
• free tier with 1M tokens included monthly

Cons

• Per-token usage fees escalate quickly for high-volume agents
• early-stage product with potential breaking changes
• workspace isolation adds cost

Cost

Free tier (1M tokens/month); Standard $2.50 per 1M tokens; Enterprise custom pricing with dedicated support

Verdict

Best for AI agent developers needing persistent memory across sessions with multi-backend flexibility and preference for pay-as-you-go models.
