AllSeated became Prismm and is moving to Cvent. Five alternatives for couples, planners and venues, with who each one suits and how to move your plan across.
AllSeated is now Prismm, and after Cvent bought it in 2025 it is moving users to Cvent Event Diagramming. Venues and planners should look at Cvent's own tools first. Couples planning one wedding have simpler options: Forever Farrah for a floor plan guests look up by QR code, SeatPlan.io for a detailed layout, WeddingWire for a free chart, and Top Table Planner for printed cards.
We make Forever Farrah, one of the options below. Every claim about other products comes from their own websites, checked on September 24, 2026.
AllSeated rebranded as Prismm, known for 3D floor plans and virtual walkthroughs sold to venues, planners and caterers. Cvent acquired Prismm in April 2025, and Cvent's migration FAQ describes moving Prismm users to Cvent Event Diagramming. If you're a couple whose venue used AllSeated, ask the venue which tool it uses now before you build anything.

If you ran events in Prismm, Cvent's own tools are the intended next step. Cvent's migration FAQ covers moving to Cvent Event Diagramming. Social Tables, also part of Cvent, offers professional diagramming with table shapes and dimensions, one-click auto-seating and live collaboration with clients. See Forever Farrah vs Social Tables.
Choose it if you're a venue or planner who needs a professional diagram shared with clients.
AllSeated was more tool than most couples needed. Forever Farrah is built for a couple planning one wedding: draw the room with real table shapes, import your guest list and let auto-seat make a first draft. On the day, guests scan a QR code and see their table on your floor plan. The layout is practical rather than to scale, and there's no 3D walkthrough for venues. Seating up to 50 guests is free, and larger weddings are a one-time $49, $99 or $199. See Forever Farrah vs AllSeated.
Choose it if you're the couple and want guests to use the chart on the day.
SeatPlan.io can import a floor plan from a photo or PDF, which helps if you have the venue's drawing from AllSeated. It offers drag-and-drop tables, spreadsheet import, PDF and Excel export, and a guest QR seat finder on paid tiers. See Forever Farrah vs SeatPlan.io.
Choose it if you want to rebuild the venue's layout closely.
WeddingWire's free seating chart gives couples a drag-and-drop layout with circular or square tables, synced with its guest list, at no cost. See Forever Farrah vs WeddingWire.
Choose it if you want a simple free chart and don't need 3D or a seat finder.
Top Table Planner runs in a browser, imports guest lists from Excel and Word, and prints seating charts, place cards and escort cards from the plan. It sells personal and professional licences.
Choose it if printed stationery is the output you need.
Our guide on how to make a wedding seating chart covers the rest.
AllSeated is now Prismm. Cvent acquired Prismm in April 2025 and is moving its users to Cvent Event Diagramming. Check Cvent's migration FAQ for the current status.
A tool built for couples rather than venues. Forever Farrah gives you a floor plan, auto-seating and a QR code guests use to find their table. WeddingWire offers a free drag-and-drop chart.
Usually not. 3D matters when a venue is selling a space or checking a layout physically fits. For deciding who sits where, a 2D plan with the right table shapes and capacities is enough.
