Now UI Kit is a free Bootstrap 4 kit made through a collaboration between InVision (design) and Creative Tim (code): 50+ UI elements and three example pages, available in HTML, PSD, and Sketch.
Being co-designed with a code vendor means the free kit ships with real matching HTML/Bootstrap markup already built, not merely static design files you'd still need to code from scratch.
Good for a fast Bootstrap-based project or refresh where you want a real, coded starting point rather than a design-only reference.
It's genuinely free with no signup required, but Creative Tim's paid Now UI Kit PRO adds substantially more components and pages if the free version proves too limited.
