Tool Information
Dify combines prompt configuration, workflows, agents, knowledge retrieval, and deployment in an application-building interface. It can be self-hosted under its published license or used through Dify Cloud. Cloud plans include workspace and message-credit limits, while connected model providers may add their own costs. That separation is easy to miss when estimating a production assistant. Build a small app with a real knowledge source and one external action, then test how it handles wrong retrieval, tool failure, and a user without permission. Exportability and deployment controls matter more than a polished demo.
Musthave review
Dify review
Dify is useful for a team that wants a visual path from prototype to callable app. Review its open-source license, cloud quotas, and model-provider billing before treating a free test as a production cost estimate.
