Preline UI

Choose Preline when the build needs the awkward widgets — a searchable advanced select, a datatable, a chart, a map, a rich text editor — because it documents the third-party wiring instead of leaving you to integrate Choices.js or ApexCharts yourself; daisyUI and Flowbite both stop short of that. Read the licence before copying: it is dual MIT + 'Preline UI Fair Use License', and redistribution is explicitly forbidden on both free and paid tiers, so never emit Preline markup into a component library or template you intend to publish. The '640+ components' figure is marketing for example variants — the real surface is about 73 component families, so verify a component exists in the docs before you assume it.

Why it is here. The free Tailwind library with the widest integration surface, and the one whose licence has a redistribution trap that an agent copy-pasting blocks will otherwise walk straight into.
