Dify vs Llama Stack: Agent Frameworks Comparison

Dify is a production-ready LLMOps platform for agentic workflow development, offering visual tools to build AI-native applications. The Sandbox tier provides 200 free GPT-4 calls, while Professional and Team plans serve independent developers and medium teams respectively. Team plan includes 10,000 message credits monthly with increased limits (200 apps, 1,000 knowledge documents, 20GB storage). Enterprise tier offers custom pricing with unlimited limits, dedicated support, SSO, and private cloud deployment. Dify is open-source and widely adopted for its easy-to-use interface enabling rapid AI application development without extensive coding.

Llama Stack is Meta open-source framework that defines and standardizes core building blocks for AI application development, providing a unified set of APIs with implementations from leading service providers. Launched to simplify deployment across different providers, Llama Stack collaborates with partners including NVIDIA NeMo microservices, IBM, Red Hat, and Dell Technologies. The framework is completely free and open-source under Meta permissive licensing, with costs only for API usage when using hosted Llama models through cloud providers. Pricing varies by model and provider: Llama 3.1 8B Instruct starts at USD 0.020/USD 0.050 per million tokens (input/output), Llama 4 Scout at USD 0.0800 per million tokens, and Llama 4 Maverick at USD 0.150/USD 0.600 per million tokens. Recent pricing reductions include 50 percent cuts for Llama 3.1 405B and Llama 3.3 70B models. While the project shows robust community activity and regular engagement calls, developers report challenges including setup and configuration complexity, build failures, import errors suggesting documentation gaps, Windows compatibility issues, and lack of security policies.
