No. Right now, we offer all plans at a full price. We are hoping to explore discounts for organisations meeting specific criteria in the future.


One test equals a single URL and Test Profile combination. The number of tests rises with the number of Pages (unique URLs) and Test Profiles and is multiplied by your test schedule.

You can monitor your usage on the Billing page. Calibre will also show predicted usage as you create a new Site. You can always upgrade or downgrade your plan and add or remove Test Pack(s) to control the test capacity.

We alert account admins once you reach 80% and 100% of the monthly test allowance, so you can decide if you’d like to act or not. When the test allocation is exhausted, Calibre will stop monitoring until of the start next billing cycle.

To increase your monthly test capacity, upgrade your plan or add Test Pack(s).

Each plan comes with a certain amount of seats included in the price. Once you reach that limit, you can add more people at $15/per seat per month or upgrade to a plan with more seats included.

Administrators are people who have complete control over your organisation.
Users are contributors who control what gets monitored and how.
Viewers have read-only access, so they are people who need to be able to view but not change performance monitoring data available in your account.

We want you to be able to view the historical performance of your Sites. That’s why we offer a lifetime snapshot data retention for all plans.

If you decide to cancel your subscription, we will immediately and permanently delete all of your data. We deeply care about your privacy and don’t keep data that isn’t necessary to be held.
