# ai-agent-book vs langflow

ai-agent-book and langflow share 5 technologies: React, Vite, FastAPI, OpenAI, and Google. Both are written in Python.

- [bojieli/ai-agent-book](https://seerepo.com/r/bojieli/ai-agent-book): 《深入理解 AI Agent：设计原理与工程实践》（李博杰 著）开源主仓库：全书正文、编译版 PDF 与按章配套代码
- [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, OpenAI, Google
- Only in ai-agent-book: Next.js, Astro, Express, Postgres, Anthropic, PostHog
- Only in langflow: Redis

- 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.
