Dify

Dify is the world's leading open-source LLM application development platform with over 139,000 GitHub stars, designed to make building production-grade AI applications accessible to everyone. Created by LangGenius, Dify provides a comprehensive visual platform that combines AI workflow orchestration, RAG pipeline management, agent capabilities, model management, and observability features into a single intuitive interface. The platform has been adopted by thousands of organizations worldwide, from startups building their first AI product to enterprises deploying complex multi-model workflows at scale.

Common Use Cases

Product teams use Dify to build customer-facing AI chatbots that answer questions from company documentation, product manuals, and knowledge bases using RAG pipelines with custom embedding and retrieval strategies. Development teams create AI-powered internal tools with visual workflows that chain multiple LLM calls, API integrations, and conditional logic without writing complex orchestration code. Content teams build AI writing assistants, translation tools, and summarization pipelines using the workflow editor with custom prompts and model configurations. Enterprises deploy Dify as a centralized AI platform where different teams can experiment with models, share workflows, and deploy AI applications while maintaining governance over API keys, costs, and data access.

Why deploy Dify on Hostinger VPS

Deploying Dify on a Hostinger VPS gives you a private AI development platform where all documents, embeddings, conversations, and API keys remain under your complete control. Self-hosting eliminates per-user pricing and usage limits of managed AI platforms while providing the flexibility to connect any LLM provider, including local models via Ollama running on the same VPS. With PostgreSQL for reliable application data, Weaviate for vector search, and Redis for caching and task queuing, Dify on Hostinger VPS provides enterprise-grade infrastructure for building and deploying AI applications. The sandboxed code execution and SSRF protection ensure security when running user-provided code and making external API calls.
