The simplest and cheapest option, built for one-page sites: a personal profile, a link hub, an event page, a landing page for a new product. Carrd does that one job beautifully, you can build a site in minutes, and the paid tier costs a few dollars a year rather than a month.
It deliberately does not scale to a multi-page business site or a store, so it is the wrong tool the moment you need more than a page. For a fast, cheap, single page, nothing is easier.
