What OSWP is
OSWP is a self-hosted wedding platform for invitations, RSVPs, planning, and its AI wedding planner, Etta. Smart invitations use personalized guest links, track them, and can automatically follow up with people who do not open them. RSVP tools cover dietary preferences, plus-ones, table assignments, and exportable guest lists. The planning board combines vendor management, task tracking, budget envelopes, and timeline views. Seating can be arranged by drag and drop or with suggestions that consider dietary needs, relationships, and family dynamics.
Users can publish an RSVP-enabled wedding website with themes, custom domains, and a registry integration layer. Etta can use planning data to answer questions and take actions such as sending guest nudges. OSWP lets users bring their own database, cloud, and AI provider. Its source-available license is FSL-1.1, with commercial hosting rights reserved. Community is free forever and includes core features and unlimited guests, but lacks managed hosting, automatic backups, and priority support. Couple costs £12 per month; Planner costs £49 per month and supports up to 10 active weddings.
