# langflow vs marimo

langflow and marimo share 18 technologies: FastAPI, uvicorn, Vite, React, jsonschema, msgspec, psutil, Tailwind CSS, class-variance-authority, tailwind-merge, Radix UI, cmdk, react-error-boundary, reactflow, Lucide, @radix-ui/react-icons, dompurify, and rehype-sanitize. 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.
- [marimo-team/marimo](https://seerepo.com/r/marimo-team/marimo): A reactive notebook for Python — run reproducible experiments, query with SQL, execute as a script, deploy as an app, and version with git. Stored as pure Python. All in a modern, AI-native editor.
