TRIP
Minimalist POI Map Tracker and Trip Planner
...It supports multi-day trip planning with detailed itineraries, which helps you move from “pins on a map” to an actionable schedule that can actually guide a real trip. TRIP also supports collaboration so you can share plans and coordinate with travel companions, making it practical for couples, groups, or families building a shared itinerary. It is designed to be easy to deploy via Docker, which makes it realistic to run on a homelab or private server, and it provides documentation for configuration including OIDC-based authentication for those who want a more integrated sign-in experience.
