Langflow

Langflow is an open-source visual workflow and agent builder designed to help developers construct AI applications. The platform features a drag-and-drop canvas where users can connect models, prompt templates, vector databases, and APIs. It serves as a visual orchestration environment that simplifies prototyping by eliminating boilerplate code. The product is useful for software engineers, product managers, and developers who want to experiment with different LLM paths. By using Langflow, teams can visually build chatbots, implement document retrieval pipelines, and design multi-agent systems. It bridges visual design and code execution by allowing users to export workflows into Python. A main difference is Langflow's developer-focused control and Model Context Protocol (MCP) support. While it provides a no-code canvas, developers can edit the underlying python code of individual components, run an interactive playground, and export flows as API endpoints. It is free to self-host, and cloud platforms offer starter sandboxes. For FutureStack, Langflow belongs in AI Agents because its core purpose is visually organizing and running complex AI agent structures. It is best for technical teams looking for a visual canvas to prototype, test, and deploy RAG applications. It is not for non-technical users seeking pre-built, customer-ready chat widgets.
