But if what you need is a hosted, managed memory API, which you can plug into your own app, both Mem0 and Zep have great offerings and are more developed along those lines:

- Not local but hosted, meaning the memory will be stored remotely on their servers via an API. - Not directly integrated with your codebase but with the agent itself, which means that memory is automatically injected and captured within Claude Code, Cursor or Codex without any custom code of your own. Their offerings are SDKs which you have to integrate yourself. - Tool agnostic, since it uses MCP, meaning that memory is not tied to one specific app.

Summary: if privacy and "works in my existing agent with no code" is what you care about, go for PMB. If you need a hosted service for your own product, go for theirs.
