The honest brief

Basic Memory

Unlike cloud memory stores, your graph stays in editable local Markdown you can open in Obsidian — portable and inspectable, not locked in a DB.

  • Plain-Markdown, local-first storage
  • Obsidian-compatible knowledge graph
  • Works across Claude, Cursor, VS Code via MCP
  • Open-source, no vendor lock-in
  • AGPL-3.0 may not suit every team
  • Cross-device sync is a paid cloud add-on
  • Setup needs a local CLI install

mem0

Fastest path to agent memory — extracts distilled facts with a tiny token footprint and the biggest community.

  • Quick to adopt, broad framework integrations
  • Stores distilled facts, small footprint
  • Vector + graph + key-value storage
  • Open-source with usable free tier
  • Weaker on temporal/state-change queries
  • LLM call on every write adds latency
  • Test deletion/conflict handling for regulated use
  • More library than full memory server
