Alternatives
The right alternative depends on what you are replacing: price, AI quality, integrations, enterprise controls, or workflow focus. Start with the closest competitors, then use the related guides to narrow the decision.

Memory infrastructure that helps AI agents retain and retrieve user context across sessions
Mem0 gives developers managed and open-source memory layers for AI agents, but retrieval quality, deletion, sensitive-data handling, training terms, and add-versus-retrieve economics need production testing.
Give stateful agents memory that reasons about people
Honcho stores conversations and derives evolving representations and conclusions that agents can retrieve as personalized context.
Turn documents, code, tables, and conversations into graph-based AI memory
Cognee is an open-source AI memory engine that combines ingestion, knowledge graphs, embeddings, relational storage, session context, retrieval, and improvement operations.
Look for an alternative if Letta is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Shortlist two options, run the same real workflow through both, and keep the one that reduces rework rather than the one with the longest feature list.
