Post Carousel by StellaCodex lets you select WordPress posts, arrange them visually, and display them with a shortcode.
Free features include unlimited carousels, manual post selection (search, add from a category, add by URL), drag-and-drop ordering, left/right arrow navigation, responsive card counts, and design controls (cards per view, border, corner radius, image ratio, card title and date).
Pro adds automatic sources (latest posts, a category, or a tag), autoplay (one-card and page-by-page) and continuous scrolling, auto-insert of a carousel at the end of post content (all posts or selected categories / tags), and carousel categories for organizing your carousels.
The free version is fully usable without a license and has no carousel-count limit.
