Mem0 alternatives in detail

  1. Letta

    freemiumApache-2.0Web, macOS, Windows, LinuxPlatform

    Letta (formerly MemGPT, Apache-2.0, ~25k stars) builds agents that manage their own memory — self-editing memory blocks, conversation search, persistence beyond any context window — exposed as an agents server/API with Python/TS SDKs and a visual Agent Development Environment. Its March 2026 pivot made Letta Code the flagship: a memory-first, model-agnostic coding harness.

  2. Zep

    freemiumApache-2.0WebPlatform

    Zep builds agent memory as temporal knowledge graphs: facts carry validity intervals, so the system tracks when things changed, not just what's true. Zep Cloud claims sub-200ms retrieval at 100M-node scale; Graphiti (~27k stars, Apache-2.0) is the open-source graph engine underneath — hybrid semantic+BM25+traversal retrieval with real-time incremental updates.
