UserGuiding
A no-code onboarding toolkit for web apps, with published prices and quotas by plan.
UserGuiding covers tours, hotspots, checklists, resource centers, surveys and NPS, a knowledge base and a product-updates page. Starter caps active content (15 guides, 10 hotspots, 1 checklist, 1 survey); Growth raises the caps and adds A/B testing, localization, custom CSS and session replay. Its FAQ says it doesn't support native mobile apps, and the pages we read don't mention desktop apps.
