What Is Dify?
Dify sits at the perfect intersection of visual development and code-first flexibility. With over 75,000 GitHub stars, it is one of the most popular open-source LLM application platforms in 2026. Think of Dify as a self-hosted alternative to no-code agent builders, but with the flexibility to drop into code whenever you need it. You design agent workflows visually, add RAG pipelines, connect tools, and deploy — all through a clean web interface, while retaining full control over your data and infrastructure.
Dify Architecture Overview
Dify’s architecture combines a visual workflow builder with a powerful backend runtime. The built-in RAG engine handles document ingestion, chunking, embedding, retrieval, and reranking. A plugin ecosystem extends functionality through community-built tools. The platform is self-hosted, giving you full control over your data and infrastructure. Workflows can mix visual drag-and-drop design with custom code blocks, offering flexibility for both non-technical builders and developers.
