dify vs langchain

Dify is an open‑source platform that lets developers and teams design, test, and deploy LLM‑powered applications using a visual canvas, Prompt IDE, and built‑in RAG pipelines. It supports hundreds of models from many providers and offers agent capabilities with function calling and ReAct tools. Available as a hosted SaaS or self‑hosted via Docker Compose, Dify provides full backend‑as‑a‑service APIs, model management, and observability, enabling quick scaling from prototype to production for engineering teams.

LangChain is an open‑source agent engineering platform that lets developers compose, customize, and deploy AI agents using large language models, tools, and prompts. It provides modular components for memory, routing, tool integration, and evaluation, enabling rapid prototyping and production‑grade deployments. The library supports multiple LLM providers, offers extensive tooling for retrieval‑augmented generation, and includes utilities for managing conversational state, making it a go‑to framework for building sophisticated AI‑driven workflows.
