Coachmark

A single-purpose headless library by sglza that gives you the compound parts of a product tour — Root, Trigger, Backdrop, Step, Positioner, Popup, Arrow, Stepper, Title, Description, Previous, Next, Close and Viewport — with no styles of its own. It sits on Base UI's Popover, so you inherit collision detection, anchoring and focus management, and it adds the two things a tour needs that a popover does not: explicit step order and a detached trigger, so one popup slides between targets instead of unmounting and remounting. Motion states (entering, exiting, repositioning, idle) are exposed as data attributes on the backdrop, positioner and popup, and out-of-view targets are scrolled into view automatically. The docs site ships live playgrounds with both Tailwind and CSS Modules implementations, plus a View as Markdown link on each page.
