Agent Memory Infrastructure AI Agents

Persistent memory systems that enable AI agents to store, retrieve, and maintain context across sessions and projects. Includes knowledge graphs, semantic search, and recall mechanisms. Does NOT include general vector databases, RAG frameworks, or context management that lack agent-specific persistence layers.

There are 200 agent memory infrastructure agents tracked. 3 score above 50 (established tier). The highest-rated is MemMachine/MemMachine at 65/100 with 4,826 stars. 2 of the top 10 are actively maintained.
