## When to reach for it

- You are choosing a memory component — what it knows.
- You are happy to depend on a hosted service and would rather not operate this yourself.

## Worth knowing

Closest thing here to memory and RAG in one product: the graph tracks contradictions and recency, and the connectors mean you are not writing an ingestion pipeline first.

## Alternatives in the memory layer

| Option | What it does | Licence | Self-host |
| --- | --- | --- | --- |
| Mem0 | Extracts durable facts from conversations and recalls them on the next turn. | open source | yes |
| Zep | Temporal knowledge graph memory — facts with validity windows, not just embeddings. | open source | yes |
| Honcho | Treats memory as a reasoning problem, not a retrieval one — you ask its Dialectic API a question about the user and get a synthesised answer. | open source | yes |
| LangMem | Memory primitives that plug straight into LangGraph checkpoints. | open source | yes |
| Cognee | Builds a graph + vector memory layer over your agent's history and documents. | open source | yes |
| Postgres (rolled by hand) | A messages table and a summaries table. Boring, auditable, yours. | open source | yes |
