# langflow vs openui

langflow and openui share 14 technologies: FastAPI, OpenAI, uvicorn, Vite, React, react-router-dom, boto3, Tailwind CSS, class-variance-authority, tailwind-merge, Radix UI, react-syntax-highlighter, Lucide, and @radix-ui/react-icons. langflow is written in Python and openui in TypeScript.

- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.
- [wandb/openui](https://seerepo.com/r/wandb/openui): OpenUI let's you describe UI using your imagination, then see it rendered live.

- 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.
