In their own words
OnePlan
OnePlan is a web platform for planning event sites and venues with suppliers, vendors, local authorities, security services and other partners. Planners can choose map options, import venue CAD files or other overlays, and arrange plans on that material. The platform calculates areas, barriers, spaces and capacities, and lets users share what3words addresses and see coordinates for objects on a plan. Real-time collaboration is listed. The Team plan supports 3–10 people with role-based editing and password-protected view-only links. Free exports are low-resolution, watermarked PNGs; Pro includes high-resolution PNG plans and CSV inventory exports. The Free plan allows one event and 25 objects, while fair-use caps limit plans to 10,000 objects per event and 500 events per account. OnePlan names festivals, local government, road events, venues, sports federations and students among its audiences. It has a free plan, a five-day trial, and paid pricing from $75/user/mo (annual).
SeatPlan.io
SeatPlan.io is a web-based seating chart maker for weddings, classrooms, events, and other gatherings. Its designer supports drag-and-drop layouts with round or rectangular tables, and users can import guest lists from CSV. Event Manager expands the workflow with floor-plan imports from photos, screenshots, PDFs, and CAD DXF files; DXF blueprints are brought in at exact scale. It also provides client links with view-only, editing, or check-in permissions and real-time updates. Door staff can check guests in from a phone link without an account. QR seat finding and Apple and Google Wallet passes are available on eligible plans. Event Temple integration imports booking guests and refreshes the roster when an event is reopened, but seating assignments do not sync back. Free costs nothing, Pro costs £8 one-time, Collaborate £14 one-time, Classroom £29 per school year when billed annually, and Event Manager £35 per month when billed annually. Event Manager has no stated guest or table limit, but imported guest-list files are capped at 5MB.
