Three plans, three meters: sim-minutes, telemetry messages and active twins. Everyone on your team can use the API at no extra charge.

Sandbox

For evaluating the API on one line or cell.

Overage rates

Team usage above the included amounts is billed at these rates on your next invoice. Sandbox stops at its limits instead.

MeterUnitTeam rate
Simulation compute time, per second sim-minute $0.06
Telemetry per 1 KB state update 1M messages $1.20
Extra twin beyond 10 active twin / month $40
State history beyond 90 days GB / month $0.10

How billing works

What counts as a sim-minute
Compute time spent running a simulation, metered per second. An 8-hour shift that simulates in 38 seconds uses 0.64 sim-minutes.
What counts as a message
One state update for one asset, up to 1 KB. Larger payloads count per 1 KB.
When usage resets
Included sim-minutes and messages reset on your monthly billing date. Unused amounts do not roll over.
No lock-in
Team is month to month with no cancellation fee. Annual billing gives two months free.

Need help building the model?

Most of the cost of a digital twin is not the license. It is modeling, system integration and calibration work (digetiers.com, 2026).

Our team can take on that part: 3D scene modeling from your CAD or layouts, equipment and process models, connector setup and calibration against your historical data. Onboarding work is scoped and quoted per project, separately from the platform subscription.

To scope a project, send us

  • Layouts or models you have (CAD, BIM, OpenUSD, point clouds)
  • Number of assets and stations in scope
  • Data sources and protocols (OPC UA, MQTT, MES, historian)
  • Hosting requirements and OT network constraints
