Coze vs Dify: Which Is Better for Building AI Agents?
Pick Coze if non-technical staff need a bot published to Feishu or WeChat by the end of the afternoon. Pick Dify if data must stay on your own servers, or you need your own models and more complex workflows.

Key differences
Coze and Dify both let you build AI apps visually: write prompts, attach a knowledge base, drag nodes into a workflow, call tools, and serve the result via API or a web page. They look alike on the surface, but the philosophies underneath are very different.
Coze is ByteDance’s hosted platform — AI building blocks for non-specialists. Its plugin store and templates cover common needs like web search and image generation, and finished bots publish straight to Feishu, WeChat Official Accounts and the web. Operations and product people can often get a support bot working in an afternoon. The trade-offs: apps and data are hosted on the platform, available models and channels follow platform policy, and the visual editor gets awkward as business logic grows.
Dify is an open-source platform for building LLM apps that you can run on your own servers, so data stays inside your network. It connects to commercial model APIs or to locally hosted open-source models. It has more engineering depth — logs, annotation and tunable retrieval suit development teams. The barrier is higher: many concepts and settings, self-hosting needs servers and ops skills, and its licence carries some commercial restrictions worth reading before building a multi-tenant service.
On price, Coze’s core features are free. Dify is free to self-host, though servers and staff time are hidden costs; a hosted cloud version also exists.
Choose Coze if
- Your team has no engineers and non-technical staff must build and maintain the bot.
- You want to publish to Feishu, WeChat Official Accounts or similar channels without integration work.
- You are building well-defined small apps: support Q&A, community assistants, daily report bots.
- You want to validate an idea before committing engineering time.
Choose Dify if
- You handle sensitive data such as contracts or customer records and need a private deployment.
- You want to use your own or local models, or compare models on quality and cost.
- Your flows need conditional branches, loops, code execution and HTTP requests.
- You have engineers to run it and plan to plug AI features into your own product.
If you are in mainland China
The mainland edition, 扣子 (Kouzi), is directly accessible, signs in with a phone number or Douyin account, offers domestic models such as Doubao and connects to the main Chinese channels — the most convenient option for non-technical teams there. Note that its features differ from the international Coze. Dify’s cloud version can be signed up for directly, but for Chinese companies the real value is self-hosting: run it on your own servers and connect compliant model APIs or local models. A common path is to validate the need quickly on Coze, then move to a self-hosted Dify once the logic gets complex and compliance requirements tighten.
