One is software from the roaster manufacturer which prompted me to contact them about certain design decisions that can cause safety problems but that also was so slow that I pulled open the electrical box to write down part numbers and look up spec sheets to find that they could be driving their whole UI a lot faster for better user experience.
The third is a competing free option that was just never really designed for larger scale use and is missing a ton of features that home roasters don't need but anybody trying to operate with batch to batch consistency should have.
