# langflow vs localGPT

langflow and localGPT share 10 technologies: React, pillow, psutil, Tailwind CSS, class-variance-authority, tailwind-merge, Radix UI, Lucide, react-markdown, and remark-gfm. 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.
- [PromtEngineer/localGPT](https://seerepo.com/r/PromtEngineer/localGPT): Chat with your documents on your local device using GPT models. No data leaves your device and 100% private.

- 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.
