# langflow vs mem0

langflow and mem0 share 3 technologies: FastAPI, Redis, and OpenAI. Both are written in Python.

- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.
- [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.

## What they share and what sets them apart

- In common: FastAPI, Redis, OpenAI
- Only in langflow: React, Vite
- Only in mem0: Postgres, Supabase, MongoDB, Anthropic, PostHog, AWS S3

## Side by side

| | langflow | mem0 |
|---|---|---|
| Size | 1,438,179 lines written, 4,003 code files | 234,363 lines written, 636 code files |
| Who writes it | 1.5% of its commits signed by AI. With Claude Code, CodeRabbit, GitHub Copilot, Cursor, Codex, and Warp | 3.6% of its commits signed by AI. With Claude Code and Cursor |
| Activity | Last push October 27, 2026, 17,563 commits, 156,046 stars | Last push October 26, 2026, 2,650 commits, 67,923 stars |
| Tests | 3,061 test files. 34.4% of its code files have a test that imports them | 324 test files. 46.2% 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.
