EventDiagram vs Table-Plan.com

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.

Table-Plan.com is a browser-based tool for creating and managing event seating charts. Guests can be added by pasting names one per line from a spreadsheet, RSVP list, or notes. The editor supports round and long tables, chair rows, and room features such as a dance floor, stage, bar, or DJ booth. Users can drag guests into seats, swap assignments, color-code groups, and track how many guests remain unseated. Premium and Pro let guests use a shared link or QR code to look up their name and see their table and seat. Charts can be exported as images or PDFs, guest data as CSV, and Print Studio can prepare place cards, posters, table lists, and QR signs. Pro adds a password-protected project link for clients to edit charts without an account. The editor runs in a modern browser on Mac, Windows, and Chromebook, and is designed for laptop or desktop screens; guests can open shared plans on phones. Free allows up to 30 guests and one project. Premium is $29, paid once and valid for three months; Pro is $49 a month.
