Which one is for you
Pick Rasa if

Look elsewhere if
- Tight if you grow: the free edition stops at one bot per company
- Skip it if you want a price list, because Enterprise is sold through sales
- Not for you if you lack engineers, since Kubernetes is the documented scale path
- Watch out: the AudioCodes phone connector is an extra purchase
Pick Voiceflow if

- Makes sense if you want chat and voice agents on one platform
Look elsewhere if
- Not for you if you want a price, as businesses book a demo and request pricing
- Watch out: the free trial is listed for agencies and partners, and its rates are not shown
- Skip it if you want general automation, since the site focuses on support and CX
- Not for you if you want a free plan, because none is shown

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
