Comparison

OnePlan vs Iventis — and the question both leave open

If you're choosing between OnePlan and Iventis, you're choosing between two event planning platforms. Based on their public materials: OnePlan leans into GIS depth — accurate mapping and digital twins. Iventis leans into multi-stakeholder collaboration — shared plan production and transport planning. Both produce a plan.

The question neither answers: who runs the event after the plan is agreed? On show days, operators fall back to radios, spreadsheets, and PDFs. That gap is where MasterGrid sits — the geo-referenced map becomes the live database that runs power, incidents, equipment, staff, and carbon through the show. The table below compares all three honestly.

Common questions

Is OnePlan or Iventis better?

It depends on your planning workflow. Based on their public materials: OnePlan leans into GIS depth — accurate mapping, digital twins, and the Esri/ArcGIS ecosystem. Iventis leans into multi-stakeholder collaboration — shared plan production, scheduling, and transport/logistics metrics. Both are planning-phase platforms; neither is built to run live operations during the event.

What do OnePlan and Iventis have in common?

Both produce event site plans: accurate maps, CAD integration, collaboration, and visualization. Both are strongest before gates open — the output is a plan that other systems and teams then execute.

What if I need to run the event, not just plan it?

That is the gap MasterGrid covers. The geo-referenced map is a live database through the show: power distribution and load monitoring, NIMS/ICS incident command with an evidence chain, equipment custody, staff deployment, vendor onboarding, and carbon accounting reconciled against live load data.

Can MasterGrid replace OnePlan or Iventis?

For operations teams, generally yes — MasterGrid covers geo-referenced site planning and continues into live operations. Teams that need 3D digital-twin deliverables for the planning phase sometimes keep a dedicated planning tool alongside it.

Plan it once. Run it live.

MasterGrid is onboarding a limited cohort of operations teams for the 2026 season. Upload your CAD, and run the event — power, incidents, equipment, and carbon on one live map.
