# mem0 vs memU

mem0 and memU share 3 technologies: OpenAI, alembic, and Pydantic. Both are written in Python.

- [mem0ai/mem0](https://seerepo.com/r/mem0ai/mem0): The Memory Layer for AI Agents - Drop-in memory infrastructure for AI agents and apps. Context that persists. Built for production.
- [NevaMind-AI/memU](https://seerepo.com/r/NevaMind-AI/memU): Personal memory across agents

## What they share and what sets them apart

- In common: OpenAI, alembic, Pydantic
- Only in mem0: FastAPI, psycopg, Qdrant, Postgres, PostHog, Anthropic, uvicorn, SQLite, Redis, Supabase, @azure/search-documents, @pinecone-database/pinecone, @zilliz/milvus2-sdk-node, cassandra-driver, chromadb, Elastic, MongoDB, MySQL, oracledb, weaviate-client, AWS S3, Mistral AI, Rich, SQLAlchemy, bcrypt, cryptography, passlib, python-jose, mem0ai, strands-agents, jsonschema, boxen, ora, @opencode-ai/plugin, earendil-works, typebox, ai, ai-sdk, Zod, LangChain, @azure/identity, @aws-sdk/client-bedrock-runtime, ollama, @turbopuffer/turbopuffer, cohere-ai, groq-sdk, Hugging Face, Cloudflare

## Side by side

| | mem0 | memU |
|---|---|---|
| Size | 236,036 lines written, 624 code files | 34,590 lines written, 154 code files |
| Who writes it | 3.6% of its commits signed by AI. With Claude Code and Cursor | 27.9% of its commits signed by AI. With Claude Code, Codex, Cursor, and GitHub Copilot |
| Activity | Last push November 4, 2026, 2,653 commits, 68,421 stars | Last push November 5, 2026, 462 commits, 14,607 stars |
| Tests | 324 test files. 47.1% of its code files have a test that imports them | 63 test files. 61.7% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
