# langflow vs OpenBB

langflow and OpenBB share 3 technologies: React, Vite, and FastAPI. 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.
- [openbq-org/OpenBB](https://seerepo.com/r/openbq-org/OpenBB): Open Data Platform for analysts, quants and AI agents.

## What they share and what sets them apart

- In common: React, Vite, FastAPI
- Only in langflow: Redis, OpenAI
- Only in OpenBB: None

## Side by side

| | langflow | OpenBB |
|---|---|---|
| Size | 1,438,179 lines written, 4,003 code files | 923,594 lines written, 2,029 code files |
| Who writes it | 1.5% of its commits signed by AI. With Claude Code, CodeRabbit, GitHub Copilot, Cursor, Codex, and Warp | 0.1% of its commits signed by AI. With Claude Code, Cursor, and GitHub Copilot |
| Activity | Last push October 27, 2026, 17,563 commits, 156,046 stars | Last push October 24, 2026, 6,062 commits, 74,783 stars |
| Tests | 3,061 test files. 34.4% of its code files have a test that imports them | 1,089 test files. 3.5% 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.
