Duva vs OSWP

Duva is a web platform for wedding websites, guest lists, RSVPs, messaging, and planning. Its site builder supports pages for schedules, travel, galleries, registries, FAQs, and RSVP responses. Guests can respond through a personalized link or household name lookup without installing an app or creating a Duva account. Organizers can assign guests to separate ceremonies and track headcounts and responses for each event. The guest list accepts CSV imports and per-event assignments; Duva describes it as designed for 500+ guests. A free planner includes a categorized checklist, an estimate-versus-actual budget tracker, and a vendor tracker. Invitations and reminders can go by SMS to +1 numbers and WhatsApp to supported numbers outside +1. Replies sent directly to those messages do not record an RSVP; guests need to use the browser page. Duva also offers more than 25 animated save-the-date designs, with free and premium options. The free plan includes the website, RSVP, guest list, checklist, budget, and vendor tracker. One-time paid options include messaging unlock for $10 as a one-time purchase. Duva supports multiple events but does not offer custom domains.

OSWP is a wedding platform for managing invitations, RSVPs, planning and multiple events, with self-hosted and web options. Its invitations use personalised guest links, track activity and follow up automatically with people who have not opened them. RSVP tools handle dietary preferences, plus-ones, table assignments and guest-list exports. A planning board brings together vendors, tasks, budget envelopes and timeline views. Seating can be arranged by drag and drop or suggested automatically with dietary needs, relationships and family dynamics in mind. Couples can publish an RSVP-enabled wedding website with themes, custom domains and a registry integration layer. Its AI planner, Etta, can use planning data to answer questions and take actions such as nudging guests. OSWP says users can supply their own database, cloud and AI provider. The Community plan is free forever, with unlimited guests and core features, but has no managed hosting, automatic backups or priority support. Couple costs £12 per month; Planner costs £49 per month and supports up to 10 active weddings.
