Dify is an open-source platform for building LLM applications \u2014 a visual workflow editor, RAG pipeline, and agent builder in one interface. It self-hosts via Docker Compose on a standard VPS: clone the repo, copy the env file, run docker compose up, and you have a working instance. Budget at least 2 vCPUs and 4 GB RAM, more if you plan to index large document sets for retrieval.<\/p>\n\n\n\n
Dify is an open-source LLM application development platform that combines a visual workflow canvas, a built-in retrieval-augmented generation (RAG) pipeline, agent orchestration<\/a>, and prompt management in a single tool. Instead of writing separate scripts to chain a document lookup, an LLM call, and a formatted response together, you build the pipeline visually and Dify handles the plumbing \u2014 vector indexing, model routing, and API exposure for whatever you build.<\/p>\n\n\n\nWhy Self-Host Dify Instead of Dify Cloud?<\/h2>\n\n\n\n
