WanderLuxe

Group trips fall apart in the gap between a chat thread and a spreadsheet. Ideas, bookings and budgets live in five places and nobody owns the plan.

• A day-by-day itinerary with accommodations, transportation, dining and activities on one timeline, plus calendar and map views.
• Shared trips with view or edit permissions and invite links, so a group plans one trip instead of forwarding screenshots.
• Budget tracking with live conversion across 150 currencies on every booking.
• An AI assistant that answers questions about the trip, searches places and the web, and parses travel documents into bookings.
• Real-time sync: an edit by one traveler appears for everyone without a refresh.
• Live flight status, weather, an iCal feed, PDF export, email reminders, and a Print Studio for a designed, printable itinerary.

1. 01

   Model the trip first

   The schema came before any screen and now spans thirty tables, every one behind row-level security. Trips, days, bookings, travelers and shares are the product; the UI is a view on them.

   Plan in phases, ship by PR

   Every feature gets pressure-tested, trimmed to what serves the group organizer, and split into PR-sized phases. Claude Code builds each phase and opens a pull request. Each PR must clear a written list of invariants before it merges.

   Harden

   A typed database client generated from the schema and one real-time hook per entity, so UI state never drifts from Postgres. Vitest unit tests, static analysis on every pull request, and an on-demand eval harness for chat, document parsing and the MCP tools.

   Operate

   Runs on Replit Autoscale. A Pro tier at $3.99 a month gates Print Studio. AI chat is free on every tier. API keys stay in edge functions and the Express server, off the client. Infrastructure cost stays near zero until usage says otherwise.
