Written by the company
UptimeRobot is a free uptime monitoring service with native iOS and Android apps that keeps an eye on your websites, APIs, servers, and critical services 24/7 (https://uptimerobot.com). The Free Plan includes up to 50 monitors with 5-minute checks and a hosted status page so you can showcase your uptime to customers. Monitor much more than simple pings: track websites and HTTP(S) endpoints, keyword/content changes, ping and port availability, DNS records, SSL certificate expiry, domain expiration, cron jobs/heartbeats, and response times, with checks running from multiple locations around the world. Get notified the moment something goes wrong via email, mobile app push, SMS, or voice call. UptimeRobot also integrates with 20+ third-party tools, including Slack, Microsoft Teams, Google Chat, Telegram, Discord, Mattermost, Zapier, PagerDuty, Splunk On-Call, webhooks, Pushover, Pushbullet, and more, so your whole team can see incidents where they already work. SMS/voice credits are included in paid plans and can be topped up on any plan as needed. Paid Solo, Team, and Enterprise plans unlock more monitors, 60-second or even 30-second checks, additional status pages, more notification and login seats, and advanced monitoring features such as SSL and domain expiry alerts, heartbeat monitoring for cron jobs, DNS monitoring, slow-response (response time) alerts, custom HTTP requests, and flexible maintenance windows. Status pages can be fully customized with your branding, own domain, privacy options, multi-language support (11+ languages), analytics, and incident announcements that customers can subscribe to via email. For automation and more complex setups, UptimeRobot offers a modern REST API (v3) that lets you manage monitors, integrations, and maintenance windows programmatically. Teams can collaborate with sub-users, admin and notify-only roles, monitor grouping, and advanced notification rules so alerts go to the right people at the right time. Stay on top of issues with UptimeRobot’s knowledge base, hosted status page, post-incident emails for major events, and an active Discord community where users, support, and developers discuss incidents, new features, and roadmap ideas in real time.

The site helps me with real-time…
The site helps me with real-time notifications of issues with my web app platform. I am abel to react right away to any downtime found by Uptime Robot so that I keep my platform running for my customers. I also like how it shows my total avg uptime as corporate or institutional clients do ask for this info.
UptimeRobot monitors are consistent and reliable
UptimeRobot enables us to monitor our websites for outages. We have depended on their consistent service for years to ensure we can quickly contact our host and pause our ads during downtime. Monitors are easy to set up, allowing our team to be notified via email in case of an outage.
Non-profit sponsorship - Uptime Robot
We really appreciate Uptime Robot non-profit sponsorship. I'm writing in behalf a Guatemalan Government Agency named SAT. They have been using this software since 2024. This platform has been very useful to them. They use Uptime Robot to monitor their locations in real time to provide a better service to the guatemalan citizens. They are willing to stay longer.
A no-fuss monitor for public facing services
Uptime Robot is a no-fuss solution to monitor availability of your public facing services. Extremely intuitive to setup and maintain! We've been using Uptime Robot for over a decade.

The best uptime tool for startups

Extremely Fast Customer service
Extremely Fast Customer service. Miso was amazing support.
Reliable and simple, but not simplistic
As a nonprofit, we've used UptimeRobot for several years because I want to be the first one to know if one of our sites or processes are misbehaving so I can resolve issues before customers and clients are even aware of them.
The recently-added location-specific monitoring, is helpful for identifying regional outages and status page announcements and notes also make it easier to communicate with users during incidents.
UptimeRobot remains affordable, very easy to set up, and reliably alerts you need when something goes down.
Beware
Beware - do not put anything production on UptimeRobot.
False alerts happening constantly, support going in circles, instead of fixing bad network infrastructure they ask us to upgrade to a higher tier package to avoid their false alerts.
Wondering if it's a business decision to send 100+ false alerts per week just to drain credits.
Life Saver for Limited Time!
UptimeRobot has been an incredibly helpful tool for managing our website uptime. As someone working in a nonprofit environment, I simply don’t have the time to constantly monitor whether our website is down or experiencing issues. Before using UptimeRobot, we often wouldn’t discover problems until much later — sometimes when someone in the community told us the site wasn’t working.
Now I receive immediate alerts if something goes wrong, which allows me to respond quickly and minimize disruption. It gives me peace of mind knowing our website is being monitored in the background while I focus on other priorities. For small teams or nonprofits with limited capacity, this tool is a huge help.
Good for my website and it's free
Essential for us
As a charity running large-scale (£50million+), online, match-funded campaigns, getting immediate alerts to any issues with Salesforce and AWS availability is vitally important. Uptime Robot provides us with a service that gives us timely alerts and enough information to quickly rectify problems. We heavily rely on the Slack integration as it means we have a central place to receive all of our alerts
Instant alerts about website downtime
Our charity has been using UptimeRobot…
Our charity has been using UptimeRobot for many years across all our sites. UptimeRobot is easy to set up, fast and reliable and the customer service prompt and friendly. We would certainly recommend UptimeRobot to others.
Simple tool for monitoring
Uptime Robot is a reliable and cost-effective solution for monitoring the availability and performance of our websites, ISP, and other public resources.
It is easy to set up and I have never had a problem with alerts.
UptimeRobot provides easy monitoring of public resources
Great for our "outside world" view of our site's reliablility.
While we do most of our monitoring with Zabbix, we also use Uptimerobot to monitor publicly facing resources so we know that things that work aren't just "hey, works on my computer!"
It's been very reliable at letting us know when things might look OK locally, but the rest of the world can't see us.
Uptime Robot is a great monitoring tool
Uptime Robot is great monitoring your websites' uptime. No fuss, no muss. You can configure how frequently to check the uptime and who to send alerts to. Additionally, it provides a historical record of downtime for your sites, if you ever need to the attention of your webhost. By placing all of your sites that site on a server on UR, it also helps you determine if you have a server issue or a site issue. I highly recommend UptimeRobot.
Great service with multiple features
This is a great service that allows you to monitor not only the uptime on your site but a number of different things live expiring SSL certs. We also use this as way to gather uptime stats for stakeholders.
