tableplanner vs AllSeated (Prismm)
Looking for AllSeated? It's been renamed twice: AllSeated became Prismm in 2024, and Prismm has since joined Cvent, the corporate events giant — its pricing now lives on cvent.com. It's seriously capable software: to-scale floor plans, photo-realistic 3D walkthroughs, venue libraries, CAD uploads. It's also unmistakably built for venues and professional planners — think demo calls, certification courses, and plans from $49 a month with a 12-month commitment.
If you're a couple who just needs to seat your guests, tableplanner is the right-sized tool: sketch your room in minutes, import your guest list, auto-seat everyone in one click — and get warned the moment two people who should be kept apart end up at the same table. No demo call, no subscription, one-time €49.
Where we're different
The stuff a bundled seating add-on never bothers with — starting with keeping the peace.
Sized for one wedding, not 96,000 planners
Prismm is industry software — venue libraries, CAD files, certification courses, sales demos. tableplanner skips all of it: open your browser, sketch the room, seat your guests. You'll be done before a demo call would have started.
Conflict detection, built in
Prismm's own marketing asks the right question — 'Carol likes Sue but not Jim. Where does Brian sit?' — but answering it is still entirely on you. tableplanner actually answers it: mark who must stay apart and it warns you the instant they land at the same table.
Auto-seat your whole list in one click
In Prismm you seat guests at tables yourself, table by table. tableplanner arranges your entire list in one click — respecting conflicts and keeping plus-ones and families together — then you fine-tune.
One-time €49, not a 12-month commitment
Prismm's paid plans run $49 to $320 per month with a 12-month commitment — priced for businesses that plan events year-round. Your wedding is one event. tableplanner is a one-time €49, free up to 30 guests.
A chart your family can actually read
Photo-realistic 3D is impressive for selling a venue — less so for deciding whether grandma is too close to the speakers. tableplanner's clean 2D chart shows names, tables, tags, and conflicts at a glance, and exports to a print-ready PDF for the venue and caterer.

Being fair
Credit where it's due: Prismm (formerly AllSeated) is the industry standard for event diagramming, now backed by Cvent. To-scale floor plans of real venues, photo-realistic 3D walkthroughs, real-time collaboration with permission levels, and meal tracking — if your venue or planner already works in it, the floor plan they hand you will be millimetre-accurate.
There's also a genuine free tier (3 events, 2 diagrams per event, guest lists up to 150), and if you're a professional running events every month, the subscription can earn its keep. For venue walkthroughs and room mock-ups, nothing in the couple-focused tools comes close.
The price
Prismm has a free tier — 1 user, 3 events, 2 diagrams per event, and a 150-guest cap per attendee list — which may cover a smaller wedding if you stay inside the limits. Beyond that it's professional pricing: $49 to $320 per month, billed on a 12-month commitment, with photo-realistic 3D rendering reserved for enterprise plans. tableplanner is built for exactly one event that matters: free up to 30 guests, then a one-time €49 for unlimited guests, conflict detection, auto-seating, collaboration, and print-ready exports. No subscription, because you only get married once.
The nosy section
The verdict
If you're a venue or a planner running events all year, Prismm (the old AllSeated) is professional-grade and worth its subscription. If you're a couple, be honest about what you need: not a digital twin of the ballroom, but every guest in a good seat — exes apart, families together, caterer informed. That's tableplanner: auto-seat in one click, conflict warnings built in, real-time collaboration in any browser, one-time €49. Let your venue keep Prismm; keep the seating for yourselves.
Build your entire chart for free. Pay the one-time €49 only when you're ready to export, print, or share.
