API and SDK Ecosystem Dify: Positions itself as a "Backend as a Service (BaaS)", which means that all its features can be accessed through the corresponding API.
Its API documentation is comprehensive and interactive, making it easy for developers to test.
The official Node.js client SDK is provided, and there is also a Go language client SDK in the community.
Coze: Also provides a comprehensive set of OpenAPI endpoints for the management of resources such as chat, workflow, session management, and knowledge bases.
Its coze-dev organization on GitHub hosts official SDKs for Python, JavaScript, Java, and Go, as well as a standalone SDK for Cozeloop.
Comparison: Coze seems to have wider language coverage than the official SDK.
It provides separate SDKs for Studio and Loop, which exactly reflects the separation of its architecture.
Both platforms adopt an API-first design approach, which is critical for integration into larger systems.
