Features
Everything you need to know when your site breaks, slows or changes
Three kinds of monitors, page-speed checks, a screenshot history, fast alerts, and the charts to understand what happened.
Website & API monitoring
Check pages and endpoints the way you define "up"
We request your page or endpoint from our servers on a schedule and judge the response by your rules.
- Expected HTTP status, such as 200-399 or an exact list
- Optional text the page must (or must not) contain, to catch error pages that still return 200 (paid plans)
- Treat slow responses as down with a response-time limit
- Follows redirects, with a configurable timeout
Server ports & cron jobs
Watch the services behind your site, and the jobs that keep it running
Not everything is a web page. Check that a server accepts connections, and that scheduled jobs actually ran.
- Server port: can we open a connection to SSH, SMTP, MySQL or any TCP port?
- Heartbeat: your cron job calls a secret URL when it finishes, and we alert you if the call doesn't arrive in time
- Report a failure explicitly from your script to be alerted immediately
Available monitor types depend on your plan.

Know how fast your pages load for desktop and mobile visitors
A real browser opens your page on a schedule, once with a desktop window and once as a phone, and records the numbers that decide whether visitors stay.
- Fully loaded time, first byte (TTFB), first paint (FCP), largest paint (LCP)
- Layout shift (CLS), page weight and number of requests
- A desktop-vs-mobile chart, so a slow release shows up immediately
- Optional slow-page alert, with a recovery message
- Choose how often per site, within your plan or add-on
Available as an add-on on any plan, or included in plans that list it.
Mobile vs desktop
Screenshots New
A visual history of every page, mobile and desktop
"Up" doesn't always mean "right". Scheduled screenshots show what visitors actually saw, so you can spot a broken layout, a missing image or an unexpected banner, and see exactly when it appeared.
- Full-page captures in a desktop view and a mobile view, every time
- Interval per site: as often as hourly on the add-on
- Kept for the number of days your plan or add-on includes
- A gallery to scroll back through, with click-to-enlarge
Available as an add-on on any plan, or included in plans that list it.
Every capture is stored as a desktop and a mobile image taken at the same moment.
Alerts
Alerts that reach you, and only when it matters
When a monitor is confirmed down you hear about it, and you hear again when it recovers.
- Email alerts on every plan
- WhatsApp alerts on paid plans
- Failures are confirmed with a quick re-check before alerting
- Reminders while a monitor stays down, at an interval you choose
- Add extra recipients, within your plan's limits
SSL & domain expiry
Don't let a certificate or domain quietly expire
An expired certificate or domain takes a site down just as surely as a crashed server. We check them regularly and warn you ahead of time.
- Certificate expiry with a warning window you choose
- Domain registration expiry, where the registry publishes it
- A notice again once it has been renewed
Included on the plans that list SSL or domain warnings.

Charts, uptime & history
See what happened and when, without exporting anything
- Response-time charts from 24 hours to 90 days
- Uptime percentage per period
- A 90-day status bar and a list of every incident with its cause and duration
- Daily or weekly summary emails on plans that include reports
Last 90 days
Plans & add-ons
Start free, add only what you need
Every account starts on the Free plan. Speed monitoring and screenshots are add-ons you can attach to any plan, including Free. They stack with your plan's limits and cancel any time.

Built so you can trust it
Private by design
Only you see your monitors, speed results and screenshots. Addresses on private or internal networks can't be monitored, which keeps the service safe for everyone.
Secure billing
Payments are processed by Stripe. Manage your card, invoices, add-ons and cancellation from your billing page.
No lock-in
Start free, upgrade when you need to, and cancel whenever you like. If you move to a smaller plan, extra monitors are paused rather than deleted.
