Dify vs OpenAI AgentKit
A side-by-side comparison of capabilities, autonomy, integrations, and pricing to help you choose.
Short answer: choose Dify if you want open-source platform for building llm apps and agentic workflows (Supervised agent, freemium); choose OpenAI AgentKit if you want openai's toolkit to build, deploy, and optimize agents from prototype to production (Supervised agent, usage).

Dify
- +Open source and self-hostable (Docker, Kubernetes) with no vendor lock-in
- +Combines workflows, RAG, agents, model management, and observability in one stack
- +Broad model support including any OpenAI-API-compatible endpoint
- -A building platform: you design and operate the apps and their guardrails
- -Self-hosting at scale requires infrastructure expertise
OpenAI AgentKit
- +Lowers the barrier to production agents with a visual builder, embeddable chat UI, connectors, evals, and guardrails in one stack
- +Native to OpenAI's API ecosystem with MCP and prebuilt enterprise connectors, plus code export to the Agents SDK
- +ChatKit and Guardrails are open-source
- -Major lifecycle risk: Agent Builder and Evals are being deprecated (shutdown November 30, 2026) about a year after launch
- -Usage-based pricing makes total cost hard to predict for heavy multi-step agents
Which should you choose?
Dify is open-source platform for building llm apps and agentic workflows, best for developers, smb, mid-market. OpenAI AgentKit is openai's toolkit to build, deploy, and optimize agents from prototype to production, best for developers, mid-market, enterprise. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
