Frequently Asked Questions
How fast will I know my site is down?
It depends on your plan: the check interval ranges from 3 min on Free to 1 min on Pro. An alert fires as soon as the confirmation threshold is met (a few consecutive failures, to avoid false-positive spam), sent to your chosen channel — Email, Telegram, Slack and more.
Do I need a credit card for the free plan?
No. Signing up for Free (10 monitors) never asks for a card. Payment is only required if and when you upgrade to a paid plan.
Which notification channels are supported?
Email and Telegram are on by default for everyone. Plus Slack, Webhooks (HMAC-signed), PagerDuty, Jira, Discord, Microsoft Teams, Mattermost, Opsgenie — and Zapier, Make.com, and n8n bridges to connect anything else.
How is this different from UptimeRobot and similar tools?
The same core checks (HTTP/SSL/Ping/DNS) plus built-in header, SEO, security, and AI-readiness diagnostics in one account — no separate subscription per tool. See a detailed breakdown on the /compare page.
Can I monitor multiple sites and bring my team?
Yes — each monitor is independent, and the limit scales with your plan. Pro and above unlock team roles (owner/admin/member/viewer) and shared incident visibility.
