In their own words
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.
GoodEvent Layout
GoodEvent Layout is web software for building visual floor plans for weddings, conferences, festivals, and other events. Drag-and-drop tools work with pre-made layouts for weddings, expos, and festivals, plus hundreds of icons for bars, chairs, marquees, trees, and other items. Users can create custom add-ons for their equipment and add ceremony seating or seated table plans. Listed structures include frame tents, Clearspan marquees, stretch tents, tipis, yurts, sail tents, pole tents, and pagodas. Teams can collaborate in real time, give staff editing access, and share view-only interactive links with clients or vendors. Links support comments and access from any device, including phones used by on-site crews. The free plan allows three projects and 50 objects per plan, with a GoodEvent watermark on PNG exports. Starter is $32 a month, billed annually at $25/mo, with unlimited projects and unwatermarked PDF/SVG export.
