TREK
Self-hosted trip planner for groups, with maps, budgets and bookings
What it is
A web app for planning trips together: build day-by-day itineraries on a map, store reservations and documents, split costs across currencies, and keep shared packing lists and to-dos. Edits sync live between trip members, and it can import booking confirmations, Google Maps lists and GPX files, then export PDFs, GPX and calendar feeds. Optional addons cover a travel journal, a visited-countries atlas and a leave calendar. Friends and families who travel together can run it on their own server instead of relying on a hosted planner.
