Sterna is a private travel hub named after the Arctic tern — the bird with the longest migration. It is for invited travellers only: there is no public sign-up.
A trip holds the plan, day-by-day schedule, documents, packing list, a shared budget, people, and a private feed. One currency per trip. English and Portuguese in the app.
It is built with Laravel and Vue as a PWA. Accounts are created by hand; there is no public sign-up. The app lives at /sterna.
