PromptFlow
LLM app development tool (superseded)
Prompt flow is a Microsoft toolkit for the full development lifecycle of LLM applications: building, testing, evaluating and deploying flows. Microsoft no longer recommends Prompt flow for new projects; in Microsoft Foundry and Azure Machine Learning it will be retired on 20 April 2027. Microsoft names Microsoft Agent Framework as the successor and provides migration samples.
