website monitoring · every 30 seconds
Website monitoring tool that catches downtime before your customers do
A website monitoring tool watches your site from the outside and tells you the moment it stops working. AlertPing checks every 30 seconds, confirms each failure from three regions, and alerts you by SMS, email, Slack or webhook in under 10 seconds.
12,000+ endpoints under watch | 38M checks a day

the 2026 baseline
What a website monitoring tool must do in 2026
A ping every 5 minutes stopped being monitoring years ago. This is the working minimum for a site that earns money.
01 · interval
Checks every 30 seconds
With a 5-minute interval, a 4-minute outage can come and go without a single probe landing on it. AlertPing probes every 30 seconds on Team and up, 60 seconds on Starter, 15 seconds on Enterprise. Worst-case detection is measured in seconds, not coffee breaks.
02 · confirmation
Multi-region confirmation
One failed probe from one network proves nothing. Frankfurt, Virginia and Singapore must all agree before anything pages you. 3 of 3, or silence.
03 · content
SSL and keyword checks
A page that returns 200 but renders a database error is still down. Keyword and JSON assertions catch it, and ssl certificate monitoring warns 30, 14, 7 and 1 day before expiry.
04 · transparency
A status page included
Every plan hosts a branded status page that updates itself from your checks, so an incident produces one page instead of forty tickets.
05 · alerting
Every alert channel
Slack messages get missed at 3am. SMS, email, Slack and webhooks ship in every plan, with escalation chains on Team and up. SMS is never a credit pack.
who it is for
Built for teams where downtime has a dollar sign
The setup is the same for everyone: add a URL, the first check runs in seconds. What changes is what an outage costs you. Full walkthrough in how to monitor website uptime.
saas
SaaS teams that sell an SLA
Monitor the app, the API and the login flow separately. JSON assertions catch a broken contract before a customer files the ticket, and SLA reports back up the quarterly review.
e-commerce
Stores where checkout is revenue
A keyword check on “Add to cart” knows the difference between a page that loads and a store that sells. Every minute of checkout downtime is a number you can calculate.
agencies
Agencies watching 40 client sites
One dashboard, one branded status page per client, flat uptime monitoring pricing that does not grow with every site you take on.

AFTER EVERY INCIDENT
Incident summary
First failed probe, confirmation time, who was paged, when recovery was confirmed. The postmortem timeline writes itself.
My hosting provider already tells me when it is down.
Your host monitors its infrastructure, not your site. A broken deploy, an expired certificate or a dead DNS record leaves the host green while your customers see an error page.
We would just build a cron job with curl.
The script works until the box running it goes down with the site. You still have to build multi-region confirmation, SMS delivery, escalation and reports. That is the product; the curl call is the easy 2%.
Our developers would notice quickly anyway.
At 3am on a Saturday? The average outage found by a customer instead of a monitor runs far longer, and it costs trust on top of revenue.
Is this another dashboard to babysit?
No. AlertPing is silent until something is confirmed down. You get the weekly digest, the alerts that matter, and nothing else.
