What Is UptimeRobot?

TL;DR (QUICK ANSWER)

UptimeRobot is a hosted uptime monitoring platform that monitors websites, APIs, servers, endpoints, ports, pings, keywords, SSL certificates, domains, DNS records, cron jobs, and response times. It alerts teams when services go down, slow down, fail checks, or need attention, using channels such as email, SMS, voice call, mobile push, and integrations.

UptimeRobot also includes public and private status pages for incident communication.

The Free plan supports up to 50 monitors with 5-minute checks, while paid plans add faster intervals, SSL and domain monitoring, more integrations, team features, and more advanced status pages.

UptimeRobot is a hosted uptime monitoring platform that helps teams detect downtime, performance issues, and service failures across websites, APIs, and online infrastructure.

A website can go down, an API can stop responding, a cron job can fail, or an SSL certificate can expire without anyone noticing right away. UptimeRobot checks these services on a schedule and alerts the right people when something changes. 

It also includes status pages for communicating incidents and uptime, along with a forever-free plan that supports up to 50 monitors with 5-minute checks.

Key takeaways

• UptimeRobot helps teams detect downtime, slow responses, certificate issues, domain risks, failed cron jobs, DNS problems, and other service interruptions.
• It supports website, API, ping, port, keyword, cron job, SSL, domain, DNS, response time, and multi-location monitoring.
• It sends alerts through email, SMS, voice call, mobile push, and integrations like Slack, PagerDuty, and webhooks.
• Status pages help teams communicate incidents, maintenance, uptime history, and service health.
• UptimeRobot is best for teams that want hosted uptime monitoring without running their own monitoring server.
• It can work alongside observability platforms, but it is not a full log, trace, or infrastructure metrics platform.

What is UptimeRobot and what does it do?

UptimeRobot works like an external watchdog for online services. You tell it what to monitor, such as a homepage, API endpoint, server, port, DNS record, SSL certificate, domain, keyword, or cron job. 

UptimeRobot checks those targets on a schedule and sends alerts when the result does not match the expected state.

It detects issues such as:

• Downtime and failed HTTP or HTTPS checks
• API failures and unreachable services
• Port, DNS, and domain-related issues
• Missing or unexpected keywords
• Failed cron jobs and background tasks
• SSL certificate errors and expiration risk
• Slow response times and regional availability problems

What can UptimeRobot monitor?

UptimeRobot supports a wide range of monitoring types, covering both infrastructure and application-level checks. 

Feature	What it does	Example use case
Website and endpoint monitoring	Checks whether a URL responds as expected	Monitor a homepage, login page, checkout page, app route, or landing page
API monitoring	Checks API availability and response behavior	Monitor health endpoints, REST APIs, or customer-facing APIs
Keyword monitoring	Checks whether expected text appears or disappears	Detect broken pages, missing content, error messages, or defaced pages
Ping monitoring	Checks whether a host responds to ping	Monitor basic server or network reachability
Port monitoring	Checks whether a TCP port is reachable	Monitor SMTP, FTP, SSH, DNS, database ports, or custom services
UDP monitoring	Checks selected UDP services	Monitor services that rely on UDP availability
Cron job monitoring	Checks whether scheduled jobs run when expected, uses a unique URL that a job or device calls to confirm it is running	Catch failed backups, imports, reports, billing jobs, or syncs, Monitor background jobs, serverless tasks, or internal services
SSL monitoring	Tracks certificate errors and expiration risk	Avoid expired certificates and HTTPS issues
Domain monitoring	Tracks domain expiration risk	Avoid outages caused by missed renewals
DNS monitoring	Checks DNS availability or record issues	Detect broken DNS changes or misconfiguration
Response time monitoring	Tracks how long a service takes to respond, alerts when response time crosses a threshold	Detect performance degradation, catch slowdowns before downtime
Multi-location monitoring	Checks availability from different locations	Detect regional outages
Maintenance windows	Prevents planned work from triggering alerts	Pause alerts during deployments or scheduled maintenance
Status pages	Shows public or private service health	Communicate incidents and uptime to users
REST API	Manages monitors and workflows programmatically	Automate monitor creation or updates
Mobile app	Sends mobile alerts and gives visibility on the go	Let teams respond away from the dashboard

How does UptimeRobot work?

UptimeRobot’s create a monitor page

UptimeRobot follows a simple monitoring workflow that runs continuously in the background:

1. You create a monitor and choose what to track, such as a website, API, server, port, or cron job.
2. Select the monitor type and how often it should be checked.
3. UptimeRobot checks the target at the selected interval from external locations.
4. The result is compared with the expected state.
5. If the monitor fails, slows down, or changes state, UptimeRobot sends an alert.
6. Your team investigates and resolves the issue.
7. Status pages can be used to communicate incidents and updates to users or internal teams.

Monitoring intervals depend on your plan:

Plan	Monitoring interval
Free	5 minutes
Solo	60 seconds
Team	60 seconds
Enterprise	30 seconds

UptimeRobot alerts and integrations

UptimeRobot monitoring is only useful if alerts reach the right people at the right time. The platform supports both direct notification channels and integrations with external tools.

Alerts can be sent through:

• Email
• SMS
• Voice call
• Email-to-SMS
• Mobile app push notifications

UptimeRobot also works with tools used for communication, incident response, and automation:

Integration type	Tools
Chat and collaboration	Slack, Microsoft Teams, Google Chat, Discord, Mattermost, Telegram
Incident response and on-call	PagerDuty, Splunk On-Call
Automation and workflows	Zapier, webhooks
Notifications and push services	Pushbullet

See the full list of integrations for more information.

UptimeRobot status pages

UptimeRobot status page example

UptimeRobot’s public status pages let teams communicate service health with customers and internal teams.

They show whether services are operational, degraded, or down, and can be used to share incidents, maintenance updates, uptime history, and response time information.

UptimeRobot supports both public and private status pages, making it possible to share updates externally with customers or internally with teams.

Status pages can be customized with branding, domains, and messaging to match your product or organization.

Who uses UptimeRobot?

UptimeRobot is used by a wide range of teams that need visibility into uptime, performance, and service health.

Audience	How they use UptimeRobot
Developers	Monitor APIs, endpoints, cron jobs, SSL certificates, and deployments
IT teams	Track websites, servers, ports, DNS, domains, and certificate health
DevOps teams	Route alerts into Slack, Teams, PagerDuty, webhooks, or on-call workflows
