Levels show who gets value from it — many tools work for both beginners and experts.
🚀 Getting started: Install with `uv pip install langflow` and run `langflow run` (or the desktop app), then start from a template flow and connect your model key.
✅ Good fit if you want a visual way to build agents and RAG pipelines and still export code.
⛔ Not for you if you want a finished app with no setup.
