No, there is no fee associated with individual users. Usage fees are paid per organization. Fees are determined by the upper limit of hosts which are allowed access in accordance with the unit price of each host established by the type of plan.

What methods of payment are available?

We accept all major credit cards (Visa, MasterCard, JCB, American Express, Diners Club, Discover). Charges are made once per month to the card on file of the amount corresponding to the fees of your chosen plan. Acceptance of other payment methods may be possible depending on your record of usage of Mackerel.

What kind of metric retention arrangement does Mackerel use?

Metric data is saved in 1 minute intervals, and as time passes it gets rounded into longer time intervals. Details

What is the trial period? What happens when the two-week trial period ends?

The trial period lasts 2 weeks from the sign-up date, and allows users to access most of the features of the Standard plan. If a user signs up for one of the available plans before the end of the trial period, the features of that plan will become available at that time, and the remaining days of the trial period will be lost. If a user does not choose any plan by the end of the trial period, the user is automatically switched to the Free plan at that time. Users are capable of changing or canceling their plan at any time.

What size of organizations are using Mackerel?
