10 Open-Source GitHub Repos That Give Your AI Agent Memory, from Mem0 (67K Stars) to Engram
victor_explore · x · 2026-10-14
A curated GitHub compilation of 10 open-source repos for giving AI agents memory (star counts as of Oct 2026):
- Mem0 (67K stars, Apache 2.0): the memory layer most agents plug into; extracts facts per user and returns only what matters.
- Hindsight (46K, MIT): memory that learns and builds on facts; works with Claude Code, Codex, Cursor.
- Codebase Memory MCP (46K, MIT): a whole-codebase map for coding agents; local, no API key.
- Graphiti (31K, Apache 2.0): tracks when each fact was true, keeping dated history.
- Cognee (31K, Apache 2.0): turns docs and chats into a graph, no API key.
Also covered: GBrain (Garry Tan's local agent brain), agentmemory (29K), Beads (28K, distributed task graph), Memvid (17K, whole memory in one offline file), and Engram (7K, one binary + SQLite).
