An LLM-agnostic memory layer that turns agent conversations and execution into persistent, queryable state stored in standard SQL databases (Postgres, MySQL, SQLite). It adds long-term memory to any LLM app with roughly one line of code, using a dual-mode system for working and long-term recall. MemoriLabs also offers a hosted enterprise memory fabric on top of the open core.

Pros & cons

  • Persistent memory in standard SQL databases
  • One-line integration, LLM-agnostic
  • No vendor lock-in; data stays in your DB
  • Apache-2.0 open source
  • Younger than Mem0/Zep, smaller ecosystem
  • SQL-first design may not suit graph use cases
  • Self-hosting means you run the database

    Mem0

    Long-term memory layer for AI agents. Self-hostable.

    Persistent memory store + retrieval pipeline for agent applications. Handles per-user/per-session/per-agent scope cleanly; pairs with OpenAI, Anthropic, and local models.

    Quick to adopt, broad framework integrations
    Weaker on temporal/state-change queries

    Zep

    Zep

    Temporal knowledge-graph memory for AI agents.

    Memory layer that gives agents long-term context by building a temporal knowledge graph from chat history and business data, tracking how facts evolve over time. It's powered by Graphiti, Zep's Apache-2.0 open-source temporal graph engine, with Zep Cloud offering a managed, credit-based service on top. Used to keep agent context relevant as conversations and data grow.

    Letta

    Stateful agents with structured memory. Successor to MemGPT.

    Open-source framework for building stateful agents — memory blocks, context-window management, tool-use primitives baked in. Useful as a reference architecture for long-running agents.

    Cognee

    Open-source memory for AI agents.

    An open-source semantic memory layer for AI agents. Cognee ingests documents, relational data, and system context, then runs an Extract-Cognify-Load pipeline that uses an LLM to build a knowledge graph with embeddings and relationships. Agents query it for durable, cross-session context that captures how concepts connect. Self-host the Python SDK for free, or use the managed cloud tiers.
