Langflow
Langflow is a free, open-source visual tool for building AI applications without writing much code. You drag pre-made blocks — an LLM, a document store, a chat input, an agent, a web-fetch tool — onto a canvas and wire them to design how information flows. It's a friendly front end over Python and LangChain: every block is real Python you can open and edit, but beginners never have to. A built-in Playground lets you chat with your flow and watch the agent reason and pick tools in real time. Typical builds are RAG chatbots that answer questions from your own PDFs or a website, and multi-step agents. Finished flows export as an API or MCP server, so a scientist could turn a literature-Q&A bot or a data-lookup assistant into something a whole lab can use.
