# airflow vs langflow

airflow and langflow share 4 technologies: React, Vite, FastAPI, and Google. Both are written in Python.

- [apache/airflow](https://seerepo.com/r/apache/airflow): Apache Airflow - A platform to programmatically author, schedule, and monitor workflows
- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.

## What they share and what sets them apart

- In common: React, Vite, FastAPI, Google
- Only in airflow: Flask
- Only in langflow: Redis, OpenAI

## Side by side

| | airflow | langflow |
|---|---|---|
| Size | 2,170,290 lines written, 4,573 code files | 1,438,179 lines written, 4,003 code files |
| Who writes it | 0.7% of its commits signed by AI. With Claude Code, GitHub Copilot, Cursor, and Devin | 1.5% of its commits signed by AI. With Claude Code, CodeRabbit, GitHub Copilot, Cursor, Codex, and Warp |
| Activity | Last push October 30, 2026, 41,577 commits, 47,329 stars | Last push October 29, 2026, 17,563 commits, 156,138 stars |
| Tests | 4,898 test files. 52.9% of its code files have a test that imports them | 3,061 test files. 34.4% 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.
