Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Amazon Lex.
- Pay-as-you-go model with no standard free tier, only AWS free credits for new customers (6 months, $200 limit)

- Variable costs can accumulate quickly for high-volume applications

Softwr does not host reviews and shows no star rating for Amazon Lex, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
