Notion is a wonderful blank canvas, and plenty of planners start there: databases for guests, a board for tasks, a page per wedding. For notes and light tracking, it is genuinely flexible and cheap.
The wall comes when a wedding needs software to compute, not just store. Notion cannot draw a seating chart that arranges guests around conflicts, it cannot group arrivals into shuttles, and its "connected" databases still need you to update everything by hand. A wedding is a logistics problem, and Notion is a document tool.
Seating, catering counts and shuttles that update from one guest list — no manual upkeep.
Open Mezze — freeMezze is wedding-native: seating computes around family politics, one guest list drives catering and transport, and arrivals group into shuttles. You keep the "everything in one place" feeling without doing the math by hand.
For notes and light tracking, yes. But Notion cannot compute a seating chart, connect RSVP changes to catering, or build shuttles from guest arrivals.
Auto-seating around conflicts, a connected guest list that updates catering and transport, and guest-arrival logistics.
It is more opinionated on purpose — built for the wedding workflow so you are not assembling it from blank pages.
