Planning your own wedding or event?
Planning events professionally?
Allseated became Prismm in 2024.
The platform continued under the Prismm name with a focus on event design, floor planning, guest seating, 3D visualization, and collaboration.
Prismm is now transitioning into Cvent Event Diagramming. According to Cvent's current transition guidance, new events should be created in Cvent Event Diagramming, while existing Prismm events can continue to be edited through June 2027.
If you originally used Allseated, that means the product you knew has gone through both a rebrand and a broader platform transition.
If you're deciding what to use next, start with a simpler question:
What did you actually use Allseated for?
Allseated itself did not simply shut down.
Allseated became Prismm in 2024, and Prismm is now transitioning into Cvent Event Diagramming.
According to Cvent's current guidance, existing Prismm events can continue to be edited through June 2027, when access to Prismm is scheduled to end.
If you're searching for an Allseated replacement because the platform has changed, this is a good time to decide which parts of your old workflow you still need.
If those needs are primarily:
PlanSeats is worth comparing.
Not every Allseated user needs the same replacement. The right option depends on what you relied on Allseated to do.
Do you need to arrange tables around the actual event space?
Do you need your guest list connected to the seating plan?
Do you need to move guests between tables and seats as plans change?
Do couples or clients need to participate in the seating process?
Are you planning one event, or managing events professionally throughout the year?
Do you repeatedly work with the same venues and want to reuse those setups?
Do you need immersive 3D event visualization, virtual venue experiences, or detailed spatial design?
That last question matters.
PlanSeats focuses on floor plans, guest organization, seating, and event collaboration.
If immersive 3D event design is central to your workflow, make that a key requirement when comparing alternatives.
If seating is the job you need to solve, PlanSeats is a more relevant comparison.
PlanSeats is built around a simple idea:
Your floor plan, tables, guest list, and seating chart should work together.
Instead of maintaining a separate floor plan, guest spreadsheet, and seating chart, keep the working plan connected.
For professional planners, PlanSeats Pro adds the recurring event workflow around that seating plan.
Allseated and PlanSeats overlap in floor planning, guest seating, and event collaboration, but they don't offer identical workflows.

The right choice depends on the work you need the software to do.
If Allseated was primarily where you organized tables and decided where guests should sit, PlanSeats solves a closely related job.
Update the working plan without rebuilding a static seating chart every time something changes.
A floor plan tells you where everything goes.
A seating chart tells you who sits there.
PlanSeats connects both.
Work with the event space, arrange the tables, then bring the guest list into the same event and begin assigning seats.
Instead of treating the floor plan as a separate diagram, use it as the foundation for the seating chart.
Your couples plan one wedding.
You plan them all year.
PlanSeats Pro gives wedding planners a repeatable way to manage the seating workflow across every couple.
Instead of rebuilding your seating process for every couple, create a system you can use again.
Professional event planners need more than one seating chart.
PlanSeats Pro gives you a workspace for managing seating across multiple events.
With unlimited events and a Multi-event Command Center, your seating workflow can stay organized across your event calendar.
Planning one event is different from managing events professionally. PlanSeats Pro gives you one workspace for your recurring event seating workflow.
Keep upcoming events together instead of organizing every seating chart as a separate project.
Start future events with venues you've already configured.
Give clients controlled access to participate in the seating process.
Use team roles to keep collaborators connected to the events they're working on.
Use Day-Of Mode when planning turns into execution.
Use catering and dietary exports to carry relevant guest information beyond the seating chart.
PlanSeats is not a like-for-like replacement for every capability associated with Allseated and Prismm.
Prismm has offered detailed 3D event visualization, virtual venue experiences, tabletop design, and other spatial-design tools.
PlanSeats does not offer an equivalent immersive 3D event-design workflow.
If detailed 3D visualization is central to the way you design or sell events, make that a key requirement when comparing your options.
If your priority is:
then PlanSeats is a more relevant comparison.
You don't need professional event software just to build one seating chart.

If you're searching for Allseated pricing, you may be trying to answer one of two questions:
What did Allseated cost?
or
What will an alternative cost me?
Allseated became Prismm, and Prismm is now transitioning into Cvent Event Diagramming. That means historical Allseated pricing isn't necessarily a useful representation of what you'll pay for the current Cvent offering.
PlanSeats pricing depends on whether you're planning one event or managing events professionally.
For a single event, you can start with PlanSeats Free and upgrade if you need more guests or tables.
For professional planning, PlanSeats Pro starts at $39.99/month or $290/year and includes unlimited events and one seat.
Choose based on the workflow you need now, rather than the pricing structure of the product you used before.
If you're moving away from Allseated or Prismm, start by identifying what you need to preserve.
PlanSeats supports guest-list import and lets you build the floor plan, tables, and seating chart within the event.
Professional users can then turn frequently used venue setups into reusable venue templates in PlanSeats Pro.
Use PlanSeats.
Start free and upgrade if your event grows beyond the Free plan limits.
Use PlanSeats Pro.
Manage unlimited events, reuse venues, collaborate with clients, and keep your professional seating workflow organized.
