What's actually paid vs. free?
Every tool is unlimited and free for any signed-in user, including DNS, SSL, port, WHOIS, hashing, and subnet math. Free also includes 3 monitors of any type with email alerts. Paid plans add more monitors, faster check intervals, webhook alerts, public status pages, and API access. If on-demand checks plus a few monitors cover you, Free is fine.
What's a 'monitor'?
A scheduled check that watches one thing, like an SSL cert's expiry, a DNS record set, a TCP port's reachability, an HTTP endpoint's status, or a domain's WHOIS expiry. It emails or webhooks you when something changes.
Can I switch plans later?
Yes. Upgrade or downgrade any time from the dashboard. Prorated, no contracts. On downgrade, monitors over your new limit are auto-paused oldest-first. Your data is kept and you can selectively unpause within the new limit.
Do you offer annual discounts?
Yes. Annual billing works out to roughly 2 months free: Starter is $90/year, Professional $290/year, Enterprise $950/year. Toggle above to see the per-month-equivalent price.
Is there a trial?
Yes. 14 days free on every paid plan. No card up front. Cancel any time before the trial ends and you won't be billed.
How are monitor checks counted?
We don't meter checks. Free is 3 monitors regardless of how often each runs, Starter is 15, Professional is 50, Enterprise is unlimited. Minimum check interval is 10 minutes on Free, 5 minutes on Starter, and 1 minute on Professional / Enterprise.
