A company and an application platform
Dify is the business name and AI application platform of LangGenius, Inc. Definition 1.3 of the company's terms identifies LangGenius as the corporation doing business as Dify, connecting the company behind the software with the product developers use. [1]
The platform connects model providers, external tools and workflow logic. In its 1.0 release, models and tools became separately installable plugins, with additional plugin types for agent strategies and external extensions. That gives Dify a place in the ecosystem as a visual application and integration layer around foundation models. [2]
The packaged 1.0 release
Dify 1.0 was published on February 28, 2025. It introduced a marketplace and an Agent node whose reasoning strategy could be supplied by a plugin. Extensions could handle external webhook events. These features broadened who could add capabilities to a Dify application without merging every model or tool into the platform's main codebase. [2]
