As part of Stripe’s “Speaker Series”, the founders behind the popular prototyping tool Framer talk about their product. There is a standard introduction here you can find elsewhere online, but I especially appreciated Bok’s and van Dijk’s breakdown of how Framer fits into the increasingly crowded prototyping market.
I find many designers tend to place a tool like Framer as an either or proposition for prototyping (e.g. “I use Framer instead of Invision”). Yet it depends heavily on both the product and what kind of interaction you’re looking to test. And in the case of Framer, there’s also the importance of basic JavaScript code familiarity. That learning curve can scare some away, while attracting others like me with a more formalized development background.
