Updated
In short: EventDiagram is ranked #1 of 24 as of 4 October 2026, ahead of OnePlan and SeatPlan.io. The best-ranked option with a free plan is OnePlan. The lowest first paid tier on this page is EventDiagram at $0.75/mo.
Planning an event layout can involve arranging seats, importing guest information, and coordinating decisions with a team. Compare seating plans and guest capacity with floor-plan import and guest-list import; a 3D view may also be relevant to how you plan a space. Team collaboration, free-plan availability, and “Paid from” details round out the listed comparison points. The ranked entries start with EventDiagram, 3D Event Designer, and SeatPlan.io, followed by EventReception and A Seat Awaits. Consider which layout and guest-planning features matter most for the event you’re organizing.
