I was skeptical but this actually seems pretty cool. I like the use of lambda to have staging and production.
I'll stick to my old-school Jekyll publishing to S3, though. You can even have a webhook hit Amazon API gateway to Lambda to build and publish. Costs me $0.03 a month per site. But I absolutely recognize that setting up a pipeline like that takes time and know-how and for some people it's worth it to pay a SaaS and that's perfectly OK too.
