Pros

Dify

• Dify provides a visual builder for defining app logic, data retrieval, decisions, tool use, and human input.
• Dify supports a marketplace for installing model providers, tools, data sources, and MCP integrations.
• Dify allows publishing apps as hosted experiences, API endpoints, embeds, or MCP-compatible tools.
• Dify offers a source-available Community Edition that can be self-hosted with Docker.
• The Enterprise edition includes SSO, SAML, RBAC, and audit logs.

Open WebUI

• Genuinely self-hostable in minutes with Docker or pip; no account or callback required
• Backend-agnostic: talks to Ollama, llama.cpp, vLLM, OpenAI, Anthropic, Groq, OpenRouter and any OpenAI-compatible API through one UI
• Built-in RAG over uploaded docs, web search, image generation, voice, and function calling
• Python pipelines and tools framework lets you extend the app without forking it
• Multi-user with roles, workspaces, model access controls, and audit-friendly logs
• Very active community with a marketplace of shared prompts, models, tools, and functions
• Enterprise tier adds SSO, RBAC, and air-gapped deployment for regulated environments

Cons

Dify

• New documents cannot be uploaded when the Knowledge Data Storage limit is reached.
• Manual editing and annotation of responses is applicable only in Chat apps.

Open WebUI

• You are responsible for hosting, updates, GPU/model provisioning, and backups
• Feature velocity is high, so breaking changes and rough edges appear between releases
• RAG and evaluation features are competent but not as deep as purpose-built tools like LangChain, LlamaIndex, or Ragas
• Enterprise pricing is not published and requires a sales conversation
• Multi-tenant performance depends entirely on the model backend you wire in; the UI cannot fix a slow local model
