What it is
OnePlan is a web platform for building event-site and venue plans with suppliers, vendors, local authorities, security services, and other partners. Planners can choose map options, add venue CAD files or other image overlays, and work over those materials. The plan calculates areas, barriers, spaces, and capacities; users can also share what3words addresses and see coordinates for placed objects. Collaboration is available in real time. The Team plan supports 3–10 people with role-based editing and password-protected view-only links. Free includes one event and 25 objects, with a low-resolution watermarked PNG export. Pro adds high-resolution PNG plans and CSV inventory exports. Pricing lists Free at no cost, Team at $90 a month, and Pro at $99 a month; paid access is also listed from $75/user/mo (annual), with a 5-day trial. OnePlan names festivals, local government, road events, venues, sports federations, and students among its audiences.
