Driver.js is a free JavaScript library for product tours, page highlights, and contextual help. It can guide users through a sequence of steps or draw attention to a single page element with a popover. Clickable hints appear as pulsing beacons and open popovers, optionally with a page overlay. Listed uses include onboarding, interactive tutorials, feature adoption, form guidance, and focusing attention. Configuration can be applied globally, to individual steps, or while a tour is running. The library works with any framework or library as well as vanilla JavaScript; it can be installed using npm, pnpm, or yarn, or loaded from a CDN. Its homepage describes it as dependency-free and about 5 KB. Driver.js is open source under the MIT license, with personal and commercial use and no attribution required. The maker also lists accessibility and support for major browsers and mobile devices. The listed platforms are Android, iOS, and web. One API constraint is that only one Driver.js instance can be active on screen at a time.
