# Awesome Agent Memory [](https://awesome.re) A curated list of memory systems, frameworks, benchmarks, and research for AI agents. Agents forget between sessions and between tools. "Agent memory" is the growing category of systems that decide what to keep, connect related facts, and improve recall over time. This list tracks the tools and research in that space. Contributions welcome. Please keep entries factual and free of marketing language. One tool per pull request, alphabetical within each section. See [Contributing](#contributing). ## Contents - [Managed memory APIs and services](#managed-memory-apis-and-services) - [Open-source frameworks and engines](#open-source-frameworks-and-engines) - [MCP memory servers](#mcp-memory-servers) - [Benchmarks and evaluation](#benchmarks-and-evaluation) - [Papers](#papers) - [Contributing](#contributing) ## Managed memory APIs and services - [GoodMem](https://goodmem.ai) - Memory layer for agentic AI with owners, roles, scoped API keys and retrieval logging, multi-modal hybrid search with reranking, available as a managed cloud or self-hosted, with SDKs in Python, TypeScript, Java, .NET and Go. - [Mem0](https://github.com/mem0ai/mem0) - Open-source (Apache-2.0) memory layer that extracts facts from conversations, plus a managed cloud, with many framework integrations. - [Mnemoverse](https://mnemoverse.com) - Persistent memory API for AI agents over MCP.
