In their own words
3D Event Designer
3D Event Designer is browser-based software for building 2D and 3D floor plans for events and other spaces. It supports event layouts, buffet and beverage diagrams, tent plans, seating charts, and inventory lists. Plans can be viewed from eye level or above in 3D. Users can make reusable templates or choose from the Floor Plan Gallery, which can help when creating similar layouts. The software includes thousands of furniture and decor options, and users can ask about incorporating their own inventory. Interactive plans can be shared by email, with clients given editing rights. It lists Agilysys and Alert integrations; website integration through its API is an add-on. It runs in a browser on computers, tablets, iPads, and phones without a download, and supports English, Spanish, French, and German. Plans start at $14.95/user/mo, and there is no free version. All plans include email support and training videos; Pro and Enterprise also include phone support and one-on-one online training.
EventDiagram
EventDiagram is a web application for making, sharing and coordinating event floor plans and diagrams. Plans use real-world dimensions, with capacity, spacing and square feet per seat recalculated as objects move. A 3D view comes from the same scene as the 2D plan and represents objects at their real heights. Its AI copilot can create or edit a to-scale layout from plain-language requests, with proposed changes left for review and approval. An MCP server and API keys let Claude or other AI tools read and write diagrams. Recipients of share links can view plans in 3D, leave pinned comments and approve a specific version without an account. Seating tools include guest-list imports, table assignments, meal and dietary tracking, and check-in. PDF, image and data exports are available on every plan, though Free exports have a watermark. The maker says private content and copilot prompts are not used to train AI models; Anthropic processes the diagram being edited for a copilot request. EventDiagram says it is not SOC 2 certified today. It offers a free plan; its pricing note lists paid plans from $9/mo. It runs on web and has an API.
