The WhatsApp allowance is not live yet. Business approval is in progress; it switches on for existing accounts automatically, at no extra cost. Everything else on these plans works today, and alerts reach you on Telegram, Slack, Teams, Discord and email meanwhile. We would rather say so here than have you find out after paying.
About the WhatsApp limits
Meta charges per delivered message, so "unlimited" would be a promise we could not keep. The caps sit far above realistic use — a monitor only messages you when something breaks. If you reach one, email keeps flowing and we will tell you, rather than going quiet.
Questions
What happens when I hit the WhatsApp limit?
Email alerts keep going out. You are never left uninformed because of a billing ceiling — the WhatsApp cap exists because Meta charges per delivered message, and email costs us almost nothing.
Do I need a card for the free plan?
No. The free plan has no card and no expiry. It is 25 monitors at 5-minute checks, and it stays that way.
Why is the free tier so generous?
Checks cost us a fraction of a cent; WhatsApp messages cost real money. Putting the paywall on monitor count would mean charging for the cheap thing. The paywall belongs on the thing with a bill attached.
Can I cancel whenever I want?
Yes, from the billing portal, and you keep the paid plan until the end of the period you already paid for. There is no cancellation flow designed to make you give up.
Who handles payment?
Polar, as merchant of record. They handle VAT and sales tax, and your card details never touch our servers.
What counts as a monitor?
One URL checked on a schedule. Cron heartbeats are counted separately, so watching a website and watching its nightly backup do not compete for the same allowance.
