Wedlio replaces printed invitations and scattered spreadsheets with a single platform. Couples get a custom subdomain (e.g. mary-and-andrew.wedlio.app) for their wedding page, dynamic RSVP forms with menu selection, smart guest seating with conflict detection, a 12-month planning checklist, and a budget tracker. Mobile-first design ensures guests can respond easily from their phones. Built for modern couples who want a paperless wedding experience.
