Claude Mem alternatives

Claude Mem is an open-source (Apache 2.0) memory plugin that records what your coding agent does, compresses it with an AI model and feeds relevant context into later sessions, in Claude Code, Cursor and Codex. The local engine is free, though its model calls bill to your provider; CMEM Pro adds hosted capture and cloud sync for $30/month after a 30-day trial.

• ByteRover

  $15/mo (Pro, billed yearly) · Free: Yes: 100 context files synced to the cloud

• Letta Code

  $20/mo (Pro, plus pay as you go overage) · Free: Yes: limited agents, 5 MiB per memory repo, bring your own keys

  Choose it when: you would switch agents rather than bolt memory onto Claude Code; Letta Code keeps memory as part of the agent, and with your own API keys usage goes to your provider instead of Letta credits.
