OSWP

What OSWP is

OSWP is a wedding platform for invitations, RSVPs, planning, guest communication, and an AI planner called Etta. It can be self-hosted, and users can bring their own database, cloud, and AI provider. Smart invitations use personalized guest links, track invitation activity, and can automatically follow up with people who do not open them. RSVP tools collect dietary preferences and plus-one details, support table assignments, and export guest lists. A planning board combines vendor management, task tracking, budget envelopes, and timeline views. Seating can be arranged by drag and drop or through suggestions that account for dietary needs, relationships, and family dynamics. Couples can publish RSVP-enabled wedding websites 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. The product page lists Claude and OpenAI for AI, Resend and React Email for email, Better Auth for authentication, and Vercel and Docker for deployment. OSWP is source-available under FSL-1.1, with commercial hosting rights reserved. The Community plan is free forever; paid plans start at £12 per month. A 14-day trial is offered.

OSWP suits couples who want invitations, RSVPs, planning tools, seating, and a wedding website in one platform. The Planner plan is aimed at wedding planners managing multiple couples, with a dashboard for up to 10 active weddings.
