What is Flowise?
Flowise is an open-source visual builder that helps you create AI workflows using LangChain components without writing code. It provides a drag-and-drop interface where you connect language models, data sources, and processing tools to build custom AI applications. The tool is designed for developers, data analysts, and technical teams who want to experiment with AI chains quickly and deploy them with minimal setup. Since it's open-source, you can self-host it, inspect the code, and adapt it to your specific needs.
