Pros
  • Zero external infrastructure: single Node process, JSON on disk
  • Triple-stream retrieval (BM25 + vectors + graph) with sub-20ms recall
  • Native plugins for Claude Code, Cursor, Cline, Windsurf, and 15+ agents
  • Apache 2.0, runs on your existing LLM subscription
  • Strong benchmark numbers (95.2% R@5 on LongMemEval-S)
  • Official, well-tested abstractions
  • Same primitives as Claude Code
  • Strong tool-use ergonomics
  • TypeScript + Python SDKs
Cons
  • Pre-1.0 (v0.9.27), expect breaking changes
  • Single-process JSON storage may not scale to team-wide deployments
  • Self-hosted only; you operate the runtime
  • Effectiveness depends on the LLM provider you wire in
  • Claude-only
  • Newer than LangGraph/CrewAI
