Registration can be tried for free, but pricing is provided by quote and no plan prices are listed. Professional includes 15 user logins; Enterprise includes all user logins and lists MFA, SSO, task management, budget management and resource management. Cvent supports pricing and transactions in more than 130 global currencies and says customers receive 24/7 support from its client services team. Its stated security credentials include certification against ISO/IEC 27001 and ISO/IEC 27701, and audits under SOC 1 and SOC 2 Type II. Attendee data is encrypted in transit with TLS 1.2 and at rest with AES-256, and payment processing is PCI DSS compliant.

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.
