Build in-app product tours, checklists, surveys, and banners with a visual builder, then show them to the right users inside your own product: that is Usertour, an open-source onboarding platform you host on your own infrastructure. Point the builder at any element on the page and it anchors steps, tooltips, and modals to your live interface, styled with themes and custom CSS so the flow looks native instead of bolted on. New users get a getting-started checklist with a progress bar; returning users meet a launcher or banner announcing the feature they have not tried; a survey asks the rest what blocked them. Targeting rules decide who sees each flow based on user attributes and behavior, so trial accounts, paying teams, and admins stop getting the same tour. Analytics report views, unique viewers, completion rate, and the exact step where people drop off, turning onboarding into something you iterate on with evidence. Everything runs from a JavaScript SDK in your app and a builder your product team can operate without filing engineering tickets.
