Regarding the design part: I usually find a couple of landing pages that I like and create something similar with the colors I prefer. Or buy one from ThemeForest.<p>Back-end: Whatever I prefer at the time. If you&#x27;re building a project with RoR, it does not mean that the landing page has to be done with that. A simple PHP&#x2F;NodeJS app works great since it can be much faster to build.<p>All in all, I try not to spend too much time on the landing page. Usually, more time is spent figuring out what&#x27;s best to show on the page itself than building it.
