Driver.js is a zero-dependency, lightweight, highly customizable, MIT Licensed, vanilla JavaScript engine that helps you drive user's focus on page. Comparing with other opensource alternaives, it's most feature-rich and is smallest in bundle size.
Just saw this share - surprised that the community only gave 40 upvotes. This a gem and very very simple to use.
DriverJS is insanely simple, but insanely powerful! The perfect balance between simplicity and magic. We offer help guides for our customers in our ERP applications. We're building in-house the missing link with our applications, with steps stored in the database, tracking of customer views, triggering of forced guides after an update etc. Without DriverJS, we wouldn't have been able to offer such clean functionality so quickly. DriverJS is easy to integrate for our development team, it's a huge time saver for our support team, our customers are better informed at the right time without having to search or contact us for help with a simple question. Everyone in-house loves it!
