Directory Builder
Build platforms where users create their own directories with custom domains. Just like DirectoryEasy.com.
Booking Platform
Let users build unlimited booking apps for services, appointments, or events with their own branded domains.
Form Builder
Create a platform where clients can build forms and publish them on custom domains with full branding.
Link in Bio
Build a platform where each user gets unlimited sites on a subdomain or their own custom domain.
Simple CRM
