Free

  • Build and run 2D hydraulic models in the browser
  • Execute ANUGA simulations in the cloud - every organisation gets 3 small runs free each day
  • Results appear in your live portal as runs complete
  • Models are location-discoverable - others in the community can learn from your work
  • Switch to Private anytime

Compute pricing

Building models is free - you only pay to run simulations. Before each run is dispatched, Hydrata estimates the compute it needs (vCPU-hours) from the size and duration of your model, and that estimate sets a simple flat price for the run. You always see the price before you launch:

Estimated compute for the run You pay
Up to $0.50 Free - every organisation gets 3 free runs per day
$0.50 to $2 $1
$2 to $5 $2
$5 to $20 $5
Over $20 Contact us for a custom quote

All prices in USD.

Paid runs draw on a prepaid credit pack ($10 or $25 - credits never expire). The Private models subscription covers privacy, not compute: runs cost the same on both plans. See the refund & billing policy for how credits, packs, and subscriptions work.

A commons for hydraulic modellers

Shared models are the foundation of the platform. A location-discoverable commons means that flood models for your region - built and run by engineers, researchers, and local authorities around the world - are findable by anyone working on the same catchment.

Hydrata is an Australian company. Making the platform free to start is part of how we support flood modelling capacity in places that need it most, regardless of budget.

Need a done-for-you verification?

Independent chartered-engineer verification is available as an add-on engagement. A Hydrata analyst runs the verification on your model and delivers a sign-off in a live review portal.
