Prismm — formerly AllSeated, and now part of Cvent — is a spatial design and event design platform. It helps venues, planners, and vendors create 3D venue layouts and photorealistic virtual walkthroughs, manage seating charts and guest lists, and collaborate in real time on event designs. Prismm's public materials highlight a large library of venue floor plans, thousands of 3D spaces, and tens of thousands of furniture and design objects, with digital-twin technology that lets venue sales and marketing teams showcase their spaces to prospects remotely. It is a mature, well-regarded product for its job: designing and selling event spaces.
ExpoFP approaches the floor plan from a different direction. It is built for trade shows, expos, and exhibitions — events where the floor plan is not just a layout, but a sales tool and a public-facing product. With ExpoFP, organizers draw and manage booth inventory, take booth reservations and online booth purchases directly from the map, publish searchable exhibitor profiles, embed the interactive plan on any website, give attendees browser-based wayfinding with no app to install, and track engagement with built-in reporting.
This page is for teams comparing ExpoFP vs Prismm, looking for an AllSeated alternative for trade shows, or deciding between event diagramming software and a dedicated trade show floor plan platform with interactive booth maps, booth sales, and attendee wayfinding. Both are strong products — the right choice depends almost entirely on the job you need done.
Both are strong products — the right choice depends almost entirely on the job you need done.
Your job is running a trade show or expo: selling booths from a live map, publishing exhibitor listings, and helping attendees find their way on the show floor from their phone's browser. For exhibition organizers specifically, ExpoFP is purpose-built for the workflow, with a free plan and published DIY pricing from $149/mo.
Your job is spatial design: weddings, galas, banquets, corporate events, or venue sales where photorealistic 3D layouts, seating charts, and virtual walkthroughs win the deal. Prismm designs the space; ExpoFP monetizes and publishes it. They solve different problems.
Prismm capabilities are based on publicly available materials as of July 2026 and should be confirmed with Prismm for your specific use case.

Trade show organizers evaluating both platforms usually land on ExpoFP for a simple reason: the floor plan on a show floor has a different job than the floor plan in a ballroom. Here's what drives the decision:
If your events are weddings, galas, banquets, or corporate functions — or if you're a venue whose sales team needs to show prospects exactly how their event will look in your space — Prismm is genuinely strong. Its photorealistic 3D visualizations, digital twins, virtual walkthroughs, seating and guest list tools, and real-time planner/venue/vendor collaboration are the product's core, backed by a decade of history as AllSeated and, more recently, Cvent's resources. For spatial design and venue sales enablement, Prismm is a category leader, and ExpoFP doesn't try to compete on photorealistic 3D room design.
The comparison ultimately comes down to what the floor plan is for. Prismm's floor plan is a design and sales artifact: it helps a planner visualize a room, a venue close a booking, and a vendor coordinate a setup. Its audience is the people producing the event. It answers the question, “What will this space look like?”
ExpoFP's floor plan is a public product: it helps an organizer sell booth space, an exhibitor get discovered, and an attendee find booth 4021 in hall B. Its audience is everyone the event touches — organizers, exhibitors, and thousands of attendees on their phones. It answers the questions, “Which booths are still available?”, “Where is this company?”, and “How do I get there?” A spatial design tool and a booth-sales map can look similar in screenshots, but they are different products doing different jobs — and choosing the wrong one means working against your tool all season.
Because the two platforms solve different problems, some organizations don't actually have to choose. A conference with both a gala dinner and an expo hall has two floor-plan jobs, not one — and each tool covers the job the other doesn't.
In practice, teams that touch both worlds tend to split the work along natural lines:

Common questions for teams comparing ExpoFP and Prismm.
For trade shows and expos, yes. If you were considering AllSeated (now Prismm) to draw an exhibition floor plan, ExpoFP is the more direct fit: it adds booth inventory, reservations, online booth sales, exhibitor listings, and browser-based attendee wayfinding on top of the interactive map. For weddings, banquets, and venue sales visualization, Prismm remains the specialist, and ExpoFP is not a substitute for photorealistic 3D room design.
