I built TripNest, a role-based group travel planner (Owner/Editor/Viewer permissions, itinerary planning, packing lists, group messaging) in a single weekend using Lovable. It looked release-ready by Sunday night. A free security scan found 8 critical issues before I ever pushed it live to real users.

The Problem

I take a lot of short trips with family and friends — mostly road trips on holidays — and organizing them is always a mess:

Fragmented info — itineraries live in someone's Notes app, flights get shared as screenshots buried in a 200-message group chat, no single source of truth.

No safe way to share control — the person who did the planning has no way to let others view the plan without risking someone accidentally deleting a hotel booking or changing dates.
