victor_explore · x · 2026-10-14
A curated list of 10 open-source GitHub projects that add memory to AI agents (excerpted).
- Mem0 (67K stars, Apache 2.0): the default memory layer, extracting facts from chats, storing them per user, returning only what matters next time.
- Hindsight (46K stars, MIT): memory that learns and builds on saved facts over time; works with Claude Code, Codex and Cursor.
- Codebase Memory MCP (46K stars, MIT): gives coding agents a map of the whole codebase instead of reading files one by one; runs locally, no API key.
- Graphiti (31K stars, Apache 2.0): remembers when a fact was true, keeping dated old facts so agents distinguish current from past truth.
- Cognee (31K+ stars) and more in the original thread.
