What it is

Promptflow is a tool for building and deploying large language model applications. It supports the entire lifecycle from initial prototyping through testing, deployment, and monitoring.

Promptflow offers a complete, open-source solution for building and deploying large language model applications, integrating seamlessly with Microsoft Azure.

When it fits — and when it doesn’t

A good fit for

  • Teams needing a comprehensive solution from prototyping to deployment of LLM apps

  • Projects that require integration with Microsoft Azure services

Look elsewhere if

  • Developers preferring cloud-based managed solutions without self-hosting

  • Small projects where full lifecycle management is not required

Known weaknesses

    Vendor lock-in with Microsoft Azure

    Optimized integrations and deployment options are heavily tied to Azure services

What it does well
