Build, host, and distribute specialized AI agents without managing the backend.
Build AI agents and retrieval workflows on a visual canvas

Dify builds AI applications with visual workflows, agents, and knowledge pipelines. Teams connect models, retrieval steps, and tools in a shared workspace, then test how the application handles requests. Published apps can be accessed through a web interface or API.
Dify Cloud provides managed hosting, while enterprise setups can run in an organization's environment or VPC. The source-available Community Edition supports self-hosting. Workspaces, logs, and deployment controls help maintain the application after the initial build. A team can inspect the workflow and its recorded activity when adjusting a retrieval step or model connection before publishing another version.
