Pay per Active Monitor
MariMetric charges by active monitor — a container you want us to continuously track — not by API calls or one-off queries. Cancel anytime, scale up or down monthly.
How active monitors work
An active monitor is a container you add to your fleet to track continuously. We refresh its status on a schedule (from 6h on Free to 5min on Business). Web one-off queries on the homepage are not counted as monitors.

Pricing FAQ
What is an active monitor?
An active monitor is a container you add to your fleet to track continuously. Web one-off homepage queries are not counted as monitors.
Why does Free limit to 5 queries per IP per day?
The limit prevents scrapers and abuse while still allowing personal one-off lookups. We prefer to be honest about limits rather than promise 'unlimited' on a free tier.
What's the difference between Starter and Pro?
Starter ($19/mo) covers 25 active monitors with 30-min refresh. Pro ($49/mo) covers 100 active monitors with 10-min refresh, REST API + MCP, 90-day history, 20 webhooks.
How does PAYG work?
PAYG ($2/active monitor) is a no-monthly-base option. Add or remove monitors any time; pay only for what's active.
Do MCP call packs expire?
No. Three pack sizes: 1K = $9, 5K = $39, 20K = $119. One-time, never expire, stackable.
Do you offer non-profit or academic discounts?
Yes. Non-profits, academic institutions, and open-source projects receive 50% off any paid plan.
Can I cancel anytime?
Yes. All paid plans are month-to-month. Cancel anytime. 14-day money-back guarantee.
Do you offer custom enterprise plans?
