The Best WordPress Uptime Monitoring Plugins in 2026

Key takeaway: Our top pick for agencies is Glow, because uptime monitoring (checks from 3 minutes, confirmed from a second region before alerting, plus SSL expiry) sits in the same dashboard as support tickets, updates, backups and client reports, and your first site is free. For a single site, a standalone monitor such as UptimeRobot or Jetpack's free downtime monitoring is enough.

Disclosure: Glow is our product.

When you manage multiple WordPress websites, consistent uptime is essential. Unexpected downtime can damage your reputation with clients and cost them revenue. That is why uptime monitoring is a core service for many WordPress agencies.

What is WordPress uptime monitoring?

Uptime monitoring checks a site's availability at regular intervals and alerts you whenever it goes offline. You can then fix problems quickly, without waiting for clients or visitors to raise the alarm.

Why does uptime monitoring matter?

• Protects revenue and reputation: quick responses to downtime prevent lost sales and keep client trust.
• Round-the-clock coverage: you know about outages even when nobody reports them.
• Professionalism: fixing problems before clients notice shows you take availability seriously.

What are the best WordPress uptime monitoring tools?

There are many uptime monitoring tools, each suited to different needs. These are popular options to consider. Check intervals, plans and pricing change, so see each vendor's site for current pricing.

Glow uptime monitor: our top pick

Glow's uptime monitor is built into the Glow platform rather than being a separate plugin. Checks run from Glow's own infrastructure at intervals from 3 minutes, and an outage is confirmed from a second region before you are alerted, which cuts false alarms. Glow also monitors SSL expiry and sends alerts by email and Slack. Because uptime sits alongside support tickets, Safe Updates, backups, security and white-label client reports, outages and the work you do to fix them sit in the same dashboard.

UptimeRobot

UptimeRobot is a well-known monitoring service that WordPress users can connect to their sites. It sends alerts when a site goes offline and is a versatile choice for agencies of all sizes. See the vendor's site for current plans and pricing.

Jetpack

Jetpack includes a downtime monitoring feature that emails you when a site is unavailable. As of November 2026, downtime monitoring is included on all Jetpack plans, including the free plan. It is simple to set up but requires a WordPress.com connection.

ManageWP Uptime Monitor

ManageWP adds uptime monitoring to its WordPress management dashboard. As of November 2026, uptime monitoring is a paid add-on charged per site on top of ManageWP's free core. Alerts and a central dashboard make it practical for agencies handling many websites.

Pingdom

Pingdom is a popular performance and uptime monitoring service. It is not a WordPress plugin, but its detailed reporting and alerts attract many agencies, and it checks from multiple locations. See the vendor's site for current pricing.

"We were previously using different tools to manage support and website updates. Having it all in one place makes life much easier." Jake Saunders, Founder, Saunders Digital

How do you choose an uptime monitor?

• One or two sites: a standalone monitor or Jetpack's free downtime monitoring is usually enough.
• Many client sites: choose a management platform with uptime built in, so alerts sit next to updates, backups and reports.
• False alarms matter: look for checks confirmed from more than one location before an alert goes out.
• Alert channels: make sure alerts reach you where you work, such as email or Slack.

Frequently asked questions

Do I need a plugin for WordPress uptime monitoring?

Not always. Many uptime monitors check your site from outside, so they work without a plugin. Glow's uptime monitor runs from Glow's own infrastructure once a site is connected.

How often should uptime be checked?

For client sites, every few minutes is a sensible target. Glow checks at intervals from 3 minutes and confirms outages from a second region before alerting.

Is there free WordPress uptime monitoring?

Yes. As of November 2026, Jetpack's downtime monitoring is free, and Glow includes uptime monitoring on your first site for free.

Does uptime monitoring cover SSL certificates?

Some tools do. Glow monitors SSL expiry alongside uptime, so you hear about an expiring certificate before visitors see a browser warning.
