    Arch is open-source, free, and easy to set up with YAML. It provides routing, observability, and safety out of the box, perfect for quick iteration without upfront cost.

  • Restaurant chain seeking to reduce labor costs
    Pick: Presto Voice

    Presto's 95% non-intervention rate can significantly reduce staff needed for order-taking while improving speed and accuracy, with measurable ROI.
