GreenMagpie: expense splitting for people who travel together

Why it surfaced

GreenMagpie combines cent-accurate receipt splitting, multi-currency debt simplification, budgets, maps, votes, and day-by-day trip planning without pretending those are separate problems. Its most memorable operational detail is also its clearest signal of intent: the site says it runs on a NAS in a shed, with no ads, tracking, or sale of user data.

An invite-only, self-hosted tool for splitting household and trip expenses, settling debts, and planning the itinerary in one shared group.
