In their own words
Aisle
Aisle helps couples plan destination weddings with venue discovery, a wedding website, guest management, RSVPs, room planning, and payments. Couples can import guest lists from spreadsheets, arrange households and groups, add plus ones, and export guest details; the standard limit is 600 guests per wedding. Guests can reply to individual events, choose meals, share dietary notes, and answer up to twelve custom questions. Room bookings and payments run through the wedding site using the couple’s connected Stripe account, with a 5% Aisle fee. Guest messages can be sent by email, SMS, and WhatsApp. Texting starts with the first membership payment; international SMS delivery depends on destination and carrier, and WhatsApp requires guest permission. Elena, the AI planner, can help find venues, estimate budgets, organize guests, and update wedding details and events. Aisle connects with Claude Desktop, Cursor, and other MCP-compatible assistants, but accessing wedding details requires sign-in and making changes requires a membership. The free setup plan costs nothing. Membership is $19.99 USD / month, with seven days free with a card.
OSWP
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.
