It's the perfect use-case for it tbh. If you read the comments here, the pricey part of Serverless is API Gateway. With Alexa Skill development the Alexa service triggers your lambda directly, bypassing API Gateway. So it's really super cheap. I have built numerous skills and my bill is literally $0.00. Alexa also gives you $100 credits per month if you build & publish a skill..which is also free.
