Pingendo – Free, simple app for Bootstrap prototyping
Slightly OT: Is it just me or is Bootstrap a bit of an overkill nowadays? I know you can import what you need and keep the lib size small but the overall framework feels aged and many feature are no rocket-science anymore. Still some features are handy but again, is it worth it?Without any customization you have this typical thousands times seen Bootstrap look. Only few of the available Bootstrap themes have an original and from Bootstrap outstanding look but then you add even more bloat to your site figuring out what CSS you could leave out. You could also customize yourself but again why not quickly do the stuff without Bootstrap? FE development got quite far these days and today's CSS and JS is not your daddy's HTML anymore, Flexbox is great and there're tons of  specialized and modular libs.Besides, Sass and Less were never my favorites but this would be a minor pick. They are ok to get along.Last but not least they claim to be mobile-first which is IMO far off and the biggest deal breaker. Just open the Bootstrap page on a newer iPhone (eg 6) and open the menu. There's some significant lag until the menu opens and then the menu-open animation sluggishly stutters running at very low framerate. This could have be done with native CSS and hardware-accelerated 3d-transforms in a responsive and butter-smooth manner with a just few lines. Just having a responsive grid-system doesn't make Bootstrap mobile-first.I believe that Bootstrap could be good for non consumer facing sites where the audience is less demanding. Eg you need to build an internal reporting dashboard for some company departments and it doesn't have to slick, smooth or sexy. Just a dashboard which is faster and more flexible than sending Excel sheets back and forth. Then yes, Bootstrap is a good choice.Don't want to be too negative, maybe it's just my cluenessless but could somebody enlighten me: why do I need else Bootstrap in 2016?
