Open Source LLM Platform RAG Agents Workflow Builder Self-Hosted Developer Tools Observability

Overview

Dify is an open-source development platform designed to simplify how teams build, deploy, and manage applications powered by large language models. It combines a visual workflow builder, prompt engineering tools, and a retrieval-augmented generation (RAG) pipeline so developers can move from prototype to production without stitching together multiple services. The platform supports a wide range of model providers, includes an agent framework for tool use and multi-step reasoning, and offers observability features to monitor usage, costs, and quality. Because it can be self-hosted, Dify appeals to organizations that need control over data, infrastructure, and compliance while still benefiting from a modern LLMOps toolchain. Typical use cases include internal knowledge assistants, customer support bots, content generation pipelines, and custom AI products that need to combine private data with commercial or open-source models.

Use cases

Build RAG-powered knowledge assistants

Use the built-in retrieval-augmented generation pipeline and knowledge base tools to create chatbots that answer questions grounded in internal documents.

Prototype and deploy LLM apps visually

Design prompts and multi-step LLM workflows in the visual builder, then move from prototype to production without integrating multiple separate services.

Orchestrate multi-step AI agents

Leverage the agent framework with tool integrations to build assistants that reason across steps and call external tools for complex tasks.

Self-host LLM apps for compliance

Deploy Dify on your own infrastructure to retain control over data and meet compliance needs while still using a wide range of LLM providers.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on agent framework with tool integrations, and visual workflow and prompt orchestration caught me off guard. Self-hosting requires technical setup and maintenance is why this isn't a perfect score, still, I'd recommend giving it a real trial.

Solid for our team

We rolled this out across the team last quarter and open-source with self-hosting options. Usage analytics and observability fits neatly into how we already work, and usage analytics and observability removed a step we used to do by hand. Self-hosting requires technical setup and maintenance, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. Multi-model provider support just works and active community and frequent updates. Self-hosting requires technical setup and maintenance can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Q&A

Which LLM providers and models does Dify support?

Dify offers multi-model provider support, allowing you to connect a wide range of LLM providers and switch between models within the same workflows. This flexibility is useful for comparing outputs, optimizing costs, or meeting provider-specific compliance requirements.

Can I self-host Dify, and what trade-offs come with that?

Yes, Dify is open-source and supports self-hosting, which gives you control over data, infrastructure, and compliance. The trade-off is that self-hosting requires technical setup and ongoing maintenance, so teams without DevOps capacity may prefer a managed deployment.

What are common use cases for Dify, and how steep is the learning curve?

Typical use cases include internal knowledge assistants and customer-facing applications built on RAG and agent workflows. Basic prototyping is approachable via the visual builder, but advanced features like agent tool use, prompt versioning, and observability have a learning curve.
