MEMORY
Mem0
Drop-in memory API that adds persistent recall of user preferences, prior decisions, and context to agents and apps without replacing the runtime.

MEMORY
Zep
Memory built on a temporal knowledge graph that tracks when facts became true and when they changed, so agents separate current information from superseded facts.
MEMORY
Letta
Agent runtime (formerly MemGPT) that lets long-running agents manage their own memory — what stays in context, what moves to storage, and what to recall later.
MEMORY
Supermemory
Hosted memory that ingests from Gmail, Drive, GitHub, and Notion, with a free open-source local server for privacy-sensitive or solo projects.
MEMORY
Cognee
Self-hosted, graph-based memory that treats memory as a data pipeline, for teams that want to own the full stack.
