Overview
LongMemory, formerly listed as OpenMemory, is a local-first, self-hosted memory engine for AI agents and LLM applications. It stores information in SQLite and lets an assistant keep and recall facts across sessions, so the application does not start from nothing each time. It ships as one TypeScript engine with an npm library, CLI, HTTP server, MCP support, dashboard and VS Code integration.
Key features
- Durable local storage on SQLite
- Recall modes including strict, historical and associative
- Explainable evidence selection with token-bounded context
- Available as npm library, CLI, HTTP, MCP and dashboard
- In-memory use needs no service or external database
Best for
Developers who want persistent, self-hosted memory for agents and tools such as Claude Desktop or Copilot without running a separate database service.
