Description
EventDiagram is a web-based event floor plan and seating chart tool built by people who produce live events. Draw a room once or start from the venue's own plan, then drag in rounds, banquet tables, stage decks, LED walls, truss, bars and decor, all true to size. Seat counts and room capacity recalculate automatically, ballroom airwall splits carry their own capacities, and the same diagram opens in 3D with one click. Instead of emailing PDFs, send one share link: clients and vendors view, comment and sign off without creating an account. An AI copilot turns a sentence like "200 guests, rounds of 10, stage north" into a to-scale draft you approve. Plans start free, then $9, $18 and $149 per month with no annual contract. Teams leaving Social Tables or Prismm get free floor plan conversion.
