Shards UI Kit is a free, modern and lightweight UI toolkit based on Bootstrap 4 that comes packed with 2 extra pre-built landing pages and 11 custom components that you can use to kick-off your next project.
There are many UI kits, including free ones. Designrevision's Shards still sticks out of the masses, as it is not only free but also very considerable and modern. Shards is the first product by Designrevision. Behind that name, there's the "design-focused software developer" (self-description) Catalin Vasile.
Since its launch, there was a lot of confusion and debate around Shards' license and the restrictions it imposed that disappointed many people willing to adopt and use it in their projects. We heard you! Licenses that create uncertainty and prevent people from using libraries like Shards are not following or promoting any of the open source principles.
