Prismm, formerly known as Allseated, is transitioning into Cvent Event Diagramming.
According to Cvent's current transition guidance, new events should be created in Cvent Event Diagramming. Existing Prismm events can continue to be edited through June 2027, when access to Prismm is scheduled to end.
If you're deciding what to use next, this is a good time to think about what you actually need from your event planning software.
Do you need detailed 3D event visualization?
Or is most of your workflow about floor plans, tables, guests, seating, and client collaboration?
If seating is at the center of your process, PlanSeats is worth comparing.
PlanSeats and Prismm overlap in event floor planning, guest seating, and collaboration, but the products have different areas of focus.
Prismm has focused heavily on detailed spatial event design, including 2D and 3D event diagrams, venue visualization, tabletop design, and immersive event experiences.
PlanSeats focuses on connecting the floor plan to the people attending the event.

The biggest difference between Prismm and PlanSeats isn't whether you can put tables on a floor plan. It's what happens around that floor plan.
Prismm has been designed for detailed spatial event planning, including 2D and 3D diagrams, immersive visualization, tabletop design, venue layouts, and guest seating.
If creating detailed 3D representations of an event is central to your workflow, those capabilities matter.
PlanSeats starts with the floor plan, then connects it to the people attending the event.
Add your tables.
Bring in your guest list.
Assign guests to tables and seats.
Collaborate with the client.
Make changes as the event evolves.
For professional planners, PlanSeats Pro turns that process into a repeatable workflow across every event you manage.
You may not need every capability of a full event-design platform.
If your recurring questions are:
PlanSeats Pro is designed around those jobs.
Bring the floor plan, tables, guest list, seating assignments, and client into one event.
Then use the same workflow for the next one.
And the one after that.
When something changes, adjust the working plan without rebuilding a separate diagram and seating spreadsheet.
Planning one seating chart is different from managing seating professionally.
With PlanSeats Pro, you can manage unlimited events from one workspace.
Use the Multi-event Command Center to keep upcoming events organized, then open each event to work on its floor plan, guest list, tables, seating chart, and client collaboration.
Instead of organizing your business around separate files and seating-chart versions, organize the work around the events themselves.
If you regularly work at the same venues, you shouldn't have to rebuild the space every time.
Your clients know their guests.
You know how to plan the event.
PlanSeats Pro gives you a way to bring those two things together.
Controlled client permissions let you invite clients into the seating process while keeping the professional event workflow organized.
Instead of passing spreadsheets, screenshots, and revised seating charts back and forth, work from the same event.
PlanSeats lets you adjust guests and seating assignments visually while keeping the floor plan and guest list connected.
Because the first seating chart is rarely the final seating chart.
The event plan still matters when planning ends.
PlanSeats Pro includes Day-Of Mode so the information you've been working with can remain useful when the event moves into execution.
Keep the current plan close instead of searching for the latest spreadsheet, screenshot, or seating-chart version.
Guest information can affect more than where someone sits.
PlanSeats Pro includes catering and dietary exports so information collected during guest and seating planning can support the people executing the event.
The guest list doesn't have to become disconnected from the rest of the event once the seating chart is finished.
PlanSeats is not a like-for-like replacement for every Prismm capability.
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.
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 the process for every couple, create a system you can use again.
Professional event planners need more than a single seating chart.
PlanSeats Pro gives you one place to manage the seating workflow across your event calendar.
Pricing is only useful when you're comparing the capabilities you actually need.
Cvent currently offers multiple Event Diagramming plans with different features and limits. Existing Prismm customers may also have different pricing during the transition.
PlanSeats Pro keeps its professional pricing straightforward.
$39.99/month

$290/year

$14.99/month per seat
or $130/year per seat
Choose the workflow that fits your business, not simply the software with the longest feature list.
The easiest way to decide whether PlanSeats fits your workflow is to use it.
Start with an actual upcoming event.
Add the floor plan.
Arrange the tables.
Bring in the guests.
Build the seating chart.
Invite the client.
See how it fits the way you already plan.
