Why Dotcom-Monitor

Website uptime monitoring software built for teams that take downtime seriously

A basic URL uptime monitor pings a server and walks away. Dotcom-Monitor goes further — running real Chrome and Edge browsers from 30+ locations to validate that logins, carts, checkouts, and APIs actually work for your customers.

1-minute checks, 30+ global locations

Detect outages in seconds, not minutes. Verify performance from where your real customers actually browse — across North America, Europe, Asia-Pacific, and South America.

Real-browser, not just pings

The best tools for monitoring website uptime check more than the server. We run real Chrome and Edge to catch broken JavaScript, slow third-party scripts, and login or checkout failures that pings miss entirely.

Instant alerts in every channel

Email, SMS, voice phone call, WhatsApp, Slack, Microsoft Teams, PagerDuty, ServiceNow, webhooks, and the mobile app. The right person knows within seconds — no matter where they are.

Start monitoring in under 5 minutes

Full access to every premium feature for 30 days. No credit card. No automatic conversion to a paid plan.

What you get

All the website uptime monitoring tools you need — in one platform

Most basic uptime monitor websites stop at HTTP pings and a single downtime alert channel. Dotcom-Monitor combines uptime, real-browser checks, API monitoring, SSL, DNS, and 20+ protocols in a single dashboard — so you get true website availability monitoring, not just a green-or-red status indicator.

FAQ

Website uptime monitoring questions, answered

What is website uptime monitoring?
Website uptime monitoring is the continuous, automated checking of a website from external locations to confirm it is online, responsive, and serving the right content. When a check fails, the service sends instant alerts so your team can fix issues before customers notice.
What is the best website uptime monitoring tool?
The best tools for monitoring website uptime combine four things: global check locations, fast check intervals (1 minute or less), real-browser testing for logins and checkouts, and instant multi-channel alerts. Dotcom-Monitor has delivered all four since 1998 and is trusted by 10,000+ organizations including Dell, Comcast, Aflac, Citrix, and Volvo.
How is a URL uptime monitor different from full website monitoring?
A basic URL uptime monitor only confirms that a server responds to a request. Full website monitoring runs real browsers to validate logins, carts, checkouts, third-party scripts, and APIs — catching the user-facing failures that simple pings miss.
How often does Dotcom-Monitor check my website?
You can run uptime checks as often as every 1 minute on paid plans, from 30+ global monitoring locations. Free plans check every 5 minutes from 2 locations.
How will I be alerted when my website goes down?
Dotcom-Monitor sends instant alerts via email, SMS, voice phone call, WhatsApp, Slack, Microsoft Teams, PagerDuty, ServiceNow, AlertOps, webhooks, and the iOS/Android mobile app — so the right person knows within seconds.
Do I need a credit card to start the free trial?
No. Your 30-day free trial includes every premium feature, every alert channel, and 30+ monitoring locations. No credit card is required and there is no automatic conversion to a paid plan when the trial ends.
Will monitoring slow down my website?
No. Synthetic uptime checks run from external Dotcom-Monitor servers and add zero load to your production infrastructure.
Can I monitor APIs and DNS along with website uptime?
Yes. The same Dotcom-Monitor account covers REST and SOAP APIs, Postman and Insomnia collections, DNS, SSL certificates, email servers, FTP, VoIP, ping, port, and 20+ other protocols — all in one dashboard.
