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LLM app development tool (superseded)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.

Probably not if

  • nobody on your team writes code (1/5 for use without developers)
  • your team is just getting started with agents (skill level: Advanced)
