Dify AI
Open-source LLM app development platform for building, deploying, and operating AI applications and agents visually.
What is Dify AI?
Visual LLM App Development Platform
Dify AI is an open-source platform for building, deploying, and operating AI applications and agents visually. It provides a full-stack development environment where developers and non-technical users can create sophisticated LLM applications — including chatbots, text generators, agents, and workflows — through a visual interface without writing code, while still offering developer-friendly APIs and extensibility.
Full-Stack AI Development
Dify covers the complete lifecycle of LLM application development. The visual prompt editor enables iterative prompt engineering with version control. The workflow builder orchestrates multi-step AI pipelines with branching logic. The knowledge base feature enables RAG by indexing documents for retrieval. Built-in observability tracks every LLM call, token usage, and performance metric.
- Visual workflow builder for multi-step AI pipelines
- Prompt engineering studio with version control

- Multi-model support: OpenAI, Anthropic, open-source LLMs
- Built-in observability and token cost monitoring
Self-Hosted and Cloud
Dify's open-source nature means organizations can self-host the entire platform for complete data privacy and control. The cloud version provides immediate access without infrastructure setup. This flexibility makes Dify equally suitable for privacy-sensitive enterprise deployments and rapid prototyping by startups and individual developers.
