What it is

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.
