Dify

Overview Dify is an open source LLM app development platform that lets you build AI agents, RAG applications, and multi step workflows visually — no framework code required for most use cases, and a code escape hatch when you need it. It launched in 2023 as a bet that the fastest way to a working AI agent should not involve reading LangChain documentation for a week. That bet paid off. In 2026, Dify is one of the three or four platforms serious teams evaluate when they need to ship an AI application in weeks, not quarters. Dify is what happens when a founder team asks: what if the workflow builder for LLMs was as good as n8n's is for automation? You open the canvas, drag an LLM node, drag a knowledge base node, wire in a conditional branch, add a code node for the edge case the UI doesn't cover, hit publish. You have an API endpoint your app can call in about the time it takes to install Python and clone a starter template. The distinctive positioning versus LangChain and CrewAI is that Dify is a platform, not a library. LangChain gives you a Python SDK and expects you to build the runtime yourself. CrewAI gives you an orchestrator for multi agent conversations. Dify gives you a hosted (or self hostable) runtime with a UI, an API, an admin console, RAG built in, model routing, prompt versioning, and a cost dashboard. The tradeoff is that you're committing to Dify's…
