2. Userflow

4.8· From $240/mo

Userflow is a lighter, cheaper onboarding builder: flows, checklists, launchers (hotspots) and a resource centre, with unlimited flows on every plan. Its own pricing page blocks automated access, so these figures come from 2026 comparisons: Startup is $240/month billed annually ($300 monthly) for up to 3,000 MAUs, with extra MAUs sold in bundles of 5,000. Pro and Enterprise add more seats, localisation and SSO.
