Flat design I'd say is the closest, although there's a ton of ways you could describe this. I'd also describe it as minimalist + a strong focus on readable typography with space to "breathe". Other sites like Digital Ocean have a great focus on simple iconography that enhances their message. All-in-all I love that design trends have gone this direction as I think it's a friendlier and more efficient means to convey information =) Years ago skeuomorphism was a popular trend which is to try to make things 3D representing real-world objects (buttons, dials, etc). Although it's still highly prevalent in UI design, we've really backed off of the trend. A great example of this is early vs. current iOS. I mention this because there's a ton of great "skeuomorphism vs flat design" stuff out there discussing the ethos of sites like this.
