pricing

charge on delivered value.

frequently asked

What counts as an active device?
An active device is a unique authenticated production device that sent at least one trace in the last 30 days. It maps cleanly to shipped usage and avoids per-trace pricing complexity.
Can I keep using TerraViewer for free?
Yes. TerraViewer is free to download and always supports local trace viewing, basic dashboards, manual trace compare, and basic exports. Paid plans add hosted value on top.
What happens when I hit the included device allowance?
Overage is billed per device only for the devices beyond the included allowance. You will see clear overage counts in the account dashboard before the invoice is issued.
What happens on downgrade or cancellation?
Premium artifacts become read-only rather than disappearing. You always keep access to your raw traces and local workflows. Re-subscribing fully restores capability.
Is there a trial?
Starter and Growth support a short trial for new workspaces. Contact sales for Enterprise pilots.
