What is UptimeRobot?
アップタイムロボット is an uptime monitoring service.
It checks your website at regular intervals.
If your site goes down, it sends you instant alerts.
Think of it like a smoke alarm for your website.
It stays quiet when things are fine.
It gets loud the second something goes wrong.
UptimeRobot tracks the availability and performance of websites, servers, and APIs.
It monitors websites and APIs 24/7.
You can monitor uptime for sites, servers, and cron jobs from one dashboard.
Unlike checking your site by hand, this monitoring service never sleeps.
It also gives you insights on uptime percentages and incident history.

Who Created UptimeRobot?
Umut Muhaddisoglu started UptimeRobot in 2010.
He was a developer in Turkey.
He wanted website monitoring that was reliable and cheap.
So he built it as a side project.
In late 2019, itrinity bought the company.
Itrianti is a software group based in Bratislava, Slovakia.
Today, UptimeRobot has:
- Over 3.5 million users who trust it for monitoring
- A 4.7-star rating from 284 reviews
- 488 reviews on Trustpilot with a 4.7 average rating
Some people still call it Uptime Robot, with a space.
Same tool, same robot.
Top Benefits of UptimeRobot
Here is what you actually get when you use UptimeRobot:

- 無料で始めよう: The generous free tier gives you 50 monitors. That is plenty for personal use and small sites.
- Fast Alerts Anywhere: Users report quick alerts during downtime incidents. You hear about it on email, SMS, or your phone.
- コスト削減: UptimeRobot helps reduce operational costs through automated checks. No one has to watch your site by hand.
- Avoid Silly Outages: UptimeRobot monitors SSL certificates and domain expiration dates to prevent outages. No more surprise expired certificates.
- Keep Users in the Loop: Public status pages can be created to communicate system health to users. Fewer “is it down?” emails.
- Easy for Small Teams: Users appreciate the easy setup and configuration. It is great for small and medium-sized businesses and IT support teams.

Best Features of UptimeRobot
Here are the standout features that make UptimeRobot worth your attention.
UptimeRobot offers 8 different types of monitoring checks.
1. Website & Endpoint Monitoring
This is the core of website monitoring.
UptimeRobot pings your URL and checks the response.
If the page fails, you get an alert.
You can also set up keyword checks.
A keyword check looks for a word on your page.
If the word disappears, something is wrong.
You can also get slow response alerts.
So you know when your response time drops, not just when the site dies.

2. Third Party Monitoring
Your site depends on other tools.
Think payment gateways, email providers, and cloud hosts.
If one of them breaks, your site breaks too.
Paid plans now monitor third-party services you rely on.
You get an alert when a vendor goes down.
That saves you hours of guessing.
UptimeRobot integrates with over 20 third-party services for alerts and workflows.

3. Multi-location Monitoring
One check from one place can lie.
A local network blip can look like downtime.
Multi-location monitoring checks from several places.
UptimeRobot supports monitoring from up to four regions.
This tells you if your site is down for everyone or just one area.
It is part of the advanced monitoring on paid plans.

4. Keyword Monitoring
Sometimes your site loads but shows an error.
A normal check would say “all good.”
Keyword monitoring catches this.
You tell it to look for a word, like your logo 文章.
Or tell it to alert you if a word like “error” shows up.
I found this one very handy for online stores.

5. False Alert Prevention
False positives are the worst.
You get woken up at 3 a.m. for nothing.
UptimeRobot double-checks before it sends a down alert.
It confirms the problem from another spot first.
This cuts noise a lot.
You only get pinged when something is really broken.

6. Domain Monitoring
An expired domain takes your whole site offline.
It happens to big brands too.
Domain monitoring watches your domain expiration date.
It also tracks your SSL certificate.
You get a warning before either one runs out.
This is available on Solo and higher plans.

7. Incident Management
When something breaks, you need a record.
Incident management logs every outage.
You see when it started, how long it lasted, and the cause.
On Team and higher plans, you can add comments and root cause notes.
Your whole team stays on the same page.
It is simple, but it works.

8. Status Page
Status pages show your users if your service is up.
Users can create branded status pages for their services.
The free plan gives you basic status pages.
Paid plans let you add your logo and put the page on your own domain.
You can make it fully customized.
You can also use private status pages for internal teams.

9. API Monitoring
APIs are how apps talk to each other.
If your API breaks, your app breaks.
API monitoring sends real requests to your endpoints.
It checks the reply and the status code.
This is great for critical services like logins or checkout.
It is included on Solo and higher plans.

10. Ping Monitoring
Ping monitoring checks if a server is alive.
It sends a tiny signal and waits for a reply.
No reply means trouble.
Port monitoring works the same way for things like email or FTP servers.
DNS monitoring checks that your domain points to the right place.
Heartbeat monitoring flips it around.
Your cron jobs and scheduled jobs ping UptimeRobot.
If a ping never arrives, you get an alert.
This cron job monitoring makes sure scheduled tasks run on time.

💡 プロのヒント: Set up a heartbeat monitor for your nightly backup. Auto monitoring of scheduled tasks ensures they execute on time.

Is UptimeRobot Worth the Price?
For most people, yes.
Paid plans start at $9 per month.
Monitoring intervals can range from every 30 seconds to 5 minutes.
Checks can be run as frequently as every 30 seconds.
UptimeRobot checks sites every 15 seconds on the Scale plan.
Faster monitoring intervals matter more than you think.
99.99% uptime allows about 4 minutes of downtime monthly.
A 5-minute check could miss that whole outage.
The Team plan normally lists at $35 per month for 100 monitors.
The Scale plan normally lists at $65 per month for 200 monitors.
Enterprise plans offer custom pricing for any number of monitors.
Team is a popular plan choice because it adds login seats for your crew.
Scale goes further and gives you unlimited status pages.
次のような場合、お金を節約できます。 You watch many sites and the free plan covers you.
次のような場合は、払い過ぎてしまう可能性があります。 You buy Solo just for more monitors. Free gives you 50, Solo gives you 10.
💡 プロのヒント: Many users find UptimeRobot affordable for managing multiple websites. Start free, then upgrade only when you need SSL alerts or faster checks.

My Experience with UptimeRobot
Here is what actually happened when I used UptimeRobot:
Here is a quick tutorial that walks you through the setup.
プロジェクト: I set up monitors for a few live websites.
I added website, keyword, and ping monitoring.
I also built a public status page.
| What I Checked | What I Found |
|---|---|
| Setup | Adding a new monitor was quick and simple |
| アラート | Down and up alerts came through fast |
| Alert channels | Email SMS 声 call, push, Slack, Microsoft Teams, Google Chat |
| モバイルアプリ | Clean app with home screen widgets |
| Status page | Easy to build and share |
私が驚いたこと: The UptimeRobot app got a full rebuild.
The new home screen widgets show your uptime without opening the app.
Recent updates also brought bug fixes and performance improvements.
You can manage monitors in the web app and get mobile app push alerts on your phone.
私がイライラしたこと: SMS voice alerts cost extra credits.
I also wish Solo had more monitors.
UptimeRobot keeps shipping new features, like third-party monitoring.
That tells me the tool is still growing.
また使うだろうか? はい。
It is a great tool for keeping watch over sites.
It also connects to Splunk On Call and webhooks for custom workflows.
⚠️ 警告: The free plan does not include SSL certificate checks, DNS checks, or maintenance windows. You need a paid plan for those.
最後に
Get UptimeRobot if: You want simple, fast alerts at a fair price.
Skip UptimeRobot if: You need deep app performance data.
私の結論: UptimeRobot does one job, and does it well.
The free plan alone beats most paid tools for small sites.
Upgrade when your whole team needs login seats and faster checks.
