WordPress Uptime Monitoring: Best Tools for Business Sites Compared on Phone Alerts, SMS and Price

The best WordPress uptime monitoring for a business site is an external monitor that checks the pages that take money every 60 seconds, recognizes the HTTP 500 and 503 errors WordPress produces when it breaks, and reaches a person by phone or SMS rather than email. ManageWP is the cheapest way to get 60 second checks across many sites. Jetpack is fine for a hobby blog. If an overnight outage costs you orders or leads, pay for alerts that repeat until someone answers.

That is the short version. The rest of this page is for the owner of a WooCommerce store, a lead generation site or a client portfolio who has to pick one tool and live with it.

What is the best uptime monitor for WordPress?

It depends on what an outage costs you and when it happens. The table below compares the tools WordPress owners actually shortlist, on the four things that decide whether an alert helps: how often it checks, where it checks from, how it reaches you and what it costs.

Prices come from each vendor's own pricing or feature page in September 2026. They change often and UptimeRobot prices in euros, so confirm on the vendor's site before you buy.

Two things stand out. ManageWP is hard to beat on price if you manage many WordPress sites and are happy with email, SMS or Slack. And only two tools on the list include voice calls at all, which matters for the one scenario email alerting cannot handle: a store or booking site that breaks at 1am.

Jetpack

Jetpack's downtime monitor runs on Jetpack's own servers, not inside your WordPress install, so it keeps working when your site is down. The free version checks every five minutes and emails you. Paid bundles move to one minute checks and add SMS. It is the obvious starting point for a personal site, and it has two limits for a business: email only on the free tier, and one notification rather than an escalation if nobody reacts.

ManageWP Uptime Monitor

A paid add-on inside ManageWP that checks every 60 seconds and alerts by email, SMS or Slack. At $1 per site, or $25 a month for up to 100 sites, it is the lowest per site cost for one minute checks we found. It makes the most sense for agencies already running updates and backups through ManageWP. Before relying on it for a store, confirm it can watch the checkout path separately, since a checkout can fail while the homepage stays up.

WP Umbrella

A WordPress maintenance platform with uptime and performance monitoring built in, at $2.19 per site per month. You pick the monitoring region, including two US locations, and an interval between 2 and 30 minutes. Alerts go to email and Slack. It suits agencies that want monitoring bundled with updates, backups and client reports, and it is less suited to a single store that needs a phone to ring.

UptimeRobot

Not WordPress specific, and that is fine, because an external monitor does not need to know what CMS it is checking. Solo gives 50 monitors at 60 second checks for roughly EUR 9 to 11 a month and includes a small monthly allowance of SMS and voice alerts. It is excellent value for email and push notification alerting. The allowance is the thing to watch if you rely on calls, because a flapping site can burn through it in a single bad night.

TrackDowntime

Ours, so weigh this accordingly. Professional checks 25 endpoints every 60 seconds and, when one fails, sends an email, an SMS and an automated phone call, then repeats the alert at 5, 10, 15, 20 and 30 minutes and onward while the site stays down. Alerts are never billed per message. Each endpoint has its own expected status code and timeout, so the WooCommerce checkout, the booking form and wp-login.php can each be watched separately. Where we lose: we are not the cheapest per site, there is no WordPress dashboard integration, and Starter at $29 a month runs five minute checks with email only. Where we win is getting a human awake when the site is down. How the detection works is covered on our downtime monitoring page.

Do I need a plugin to monitor WordPress uptime?

No, and for the alert itself you are better off without one. A monitor that runs inside WordPress stops when WordPress stops, which is exactly the moment you need it. External monitoring services request your site from their own servers, so a crashed PHP process, a dead database or a suspended hosting account still produces an alert.

Plugins are still useful for other things, such as update management, backups and security scanning. Just do not count on a plugin for the alert when the site itself is down.

How WordPress sites actually go down

Knowing how WordPress fails tells you what the monitor needs to catch. Most real outages on business WordPress sites fall into a handful of patterns, and most of them return a status code a good external monitor recognizes.

A plugin or theme update causes a fatal error. Since WordPress 5.2 a fatal PHP error shows the "There has been a critical error on this website" screen, served with an HTTP 500. A monitor expecting a 200 catches it on the first check.

The database stops answering. "Error establishing a database connection" is returned as a server error, not a normal page. This is common on shared hosting when a neighboring account exhausts resources.

An update gets stuck in maintenance mode. WordPress creates a .maintenance file during updates and serves "Briefly unavailable for scheduled maintenance" with a 503. If the update is interrupted, the file stays and the site stays down until someone deletes it.

The SSL certificate does not renew. Automated certificate renewals fail quietly more often than hosts admit. The server is healthy, and every visitor on a modern browser gets a full page security warning. Certificate expiry monitoring catches this days in advance.

The host suspends or throttles the account. Traffic spikes, a malware flag or a billing issue can put a suspension page or a redirect in front of the site. Turning redirect following off on key endpoints turns that into an incident instead of a silent pass.

The page loads, just too slowly to use. A WooCommerce checkout taking 30 seconds is effectively down during a sale. A timeout of 10 to 15 seconds on that endpoint makes slowness count as downtime.

One honest limit: a completely blank page served with a 200 status, the classic white screen, passes a status code check. Recovery mode made that much rarer after WordPress 5.2, but it is why the next section says to monitor more than the homepage.

Which WordPress pages should you monitor?

Monitor the pages where money or leads change hands, not just the homepage. Caching plugins and CDNs serve a WordPress homepage from cache long after PHP or the database has failed, so a homepage only check can report 100 percent uptime through a broken checkout.

A sensible set for a business WordPress site:

• The homepage, as the general availability signal
• The WooCommerce cart or checkout, or the booking and quote form page, which usually bypass the page cache
• wp-login.php, which always runs PHP and hits the database
• A key landing page that paid ads send traffic to, because ad spend keeps burning while it is down

That is four endpoints for one site. For an agency with 15 client sites it is closer to 30 to 45, which changes the plan you need. We cover that sizing in website monitoring for agencies.

How often should I check my WordPress site's uptime?

Every 60 seconds for anything that sells, books or captures leads, and every 5 minutes for informational sites. On a five minute interval an outage can run nearly five minutes before the monitor even looks, and with confirmation rechecks the first alert may not arrive for six or seven. One minute checks add about 1,440 requests a day per endpoint, which is negligible load and no reason to hold back.

Is email enough, or do you need phone call alerts?

Email is enough when someone is watching their inbox during the hours the site earns money. Look at your WooCommerce order times or form submissions for the last month. If a real share arrive after 8pm or at weekends, an emailed alert means you learn about the outage the next morning.

Phone calls cost more because they work. The difference between tools that offer them is what happens when you do not answer. One call and silence is the common pattern. Repeating calls until the site recovers is what downtime alerts by phone call are built around, and it is the feature to test before you commit.

Uptime is also only the floor for a store. A checkout that loads fine but loses buyers is a slower, quieter leak, and once the site is reliably up, a conversion audit of the checkout and product pages is usually where the next dollar is.

Questions WordPress owners ask before choosing a monitor

Does Jetpack monitor uptime? Yes. Jetpack's downtime monitor checks WordPress sites from Jetpack's servers every five minutes on the free plan and emails you when the site goes down and when it recovers. Paid Jetpack bundles move checks to every minute and add SMS notifications.

How do I monitor my WordPress site uptime? Add the site's key URLs to an external uptime monitoring service, set a 60 second interval for anything transactional, and add a phone number for alerts. Include the checkout or form page and wp-login.php, not just the homepage, because cached homepages hide most WordPress failures.

Can uptime monitoring detect a broken WordPress plugin? Usually, yes. A plugin that triggers a fatal error makes WordPress return an HTTP 500 critical error page, and a monitor expecting a 200 opens an incident on that check. A plugin that breaks layout or functionality without an error status will not be caught by uptime checks alone.

How much does WordPress uptime monitoring cost? From free with Jetpack's five minute email checks, to about $1 to $2 per site per month for one minute checks through ManageWP or WP Umbrella, to around $99 a month for 25 endpoints with repeating phone call and SMS alerts on TrackDowntime Professional.

Does uptime monitoring slow down WordPress? No. An external monitor makes one ordinary request per interval from outside your hosting and installs nothing on your server. If your site struggles with one request a minute, that is itself worth knowing before a real traffic spike finds it.

Picking one

If the site is a hobby or an informational blog, use Jetpack's free monitor and move on. If you manage a large WordPress portfolio on a tight budget and email or Slack alerts are enough, ManageWP's add-on is the cheapest route to one minute checks. If an outage at night costs orders, bookings or a client relationship, buy on alert behavior: 60 second checks on the checkout, a phone that rings, and alerts that keep coming until the site is back.

TrackDowntime Professional is $99 a month for 25 endpoints with those alerts included and never billed per message, and annual billing runs at roughly half. The plans and check intervals are on the pricing page, and every incident is kept in the website downtime tracker history, so you have the dates when you talk to your host.
