Why it matters
Downtime is expensive — and easy to miss
A site that's down doesn't announce itself. Uptime monitoring watches your sites and endpoints around the clock so you're the first to know, not the last, and can start fixing before it costs you customers.
Seconds
is what downtime costs
For a store or SaaS, every minute offline is lost revenue, abandoned signups, and support tickets piling up.
Customers
shouldn't be your monitor
Without uptime monitoring, the first sign of an outage is an angry email — long after the damage started.
Confirmed
before you're paged
One probe can lie — a momentary network hiccup looks like downtime. Uptura re-verifies a failure across consecutive checks before alerting, so blips don't wake you at 3am.
What we monitor
Everything an uptime monitoring tool should do
Uptura confirms your sites are online on a schedule, tracks response time, and lets you assert on keywords and status codes to define exactly what counts as healthy.
Scheduled uptime checks
Uptura checks your sites and endpoints on a schedule — as often as every 5 minutes during beta — so an outage is caught fast, not from the first support ticket.
Instant multi-channel alerts
The moment a site goes down — and again when it recovers — your team is notified over email or Slack, with the failing check attached.
Response-time & uptime history
Track latency and uptime over time, not just up or down, so you can see a site getting slower long before it actually falls over.
Content & status-code checks
Assert that a response contains a keyword and returns the status code you expect — so a 200 that quietly serves an error page still counts as down.
How it works
Add a URL, get watched around the clock
Uptime monitoring should take a minute to set up. Point Uptura at your sites and it handles the checking from there.
- 1
Add your URLs
Point Uptura at the sites, pages, and endpoints you need to keep online. No agents to install — just the addresses you care about.
- 2
We check on a schedule
Uptura probes each target on a schedule, measuring response time and confirming the server responds without a server error.

You get alerted when it's down
The instant a check fails — confirmed across consecutive checks to avoid false alarms — we alert your team, and let you know the moment the site recovers, with the downtime logged.
One platform
Uptime is just one signal Uptura watches
A site can be 'up' while its certificate is expiring, its DNS is wrong, or its checkout is broken. Uptura pairs uptime monitoring with SSL, DNS, SEO, performance, accessibility, and more — so every part of a website's health lives in one dashboard and one alert stream.
SSL & Domain
Track SSL certificate, issuer, and domain expiry across every site, with alerts well before anything lapses.
DNS Monitoring
Watch DNS records for unexpected changes, hijacks, and misconfigurations in real time.
API & Endpoint
Test REST endpoints for status codes, latency, and JSON validity — and watch business-critical endpoints separately.
SEO Monitoring
Catch metadata, canonical, robots.txt, and sitemap regressions that quietly tank rankings — the moment they ship.
Core Web Vitals
Track LCP, CLS, and TBT over time with PageSpeed Insights scans, and get alerted when performance regresses.
Synthetic & Forms
Run scripted checks on logins, checkouts, and contact forms so broken user journeys never go unnoticed.
Visual Regression
Capture daily screenshots and highlight visual differences between deployments before anyone else spots them.
Accessibility
Continuous WCAG and Axe scans with historical reports, so accessibility regressions get caught — not shipped.

FAQ
Uptime monitoring, answered
What is uptime monitoring?
Uptime monitoring is the practice of continuously checking that a website, API, or service is online and responding correctly. A monitoring tool sends requests on a schedule and alerts you the moment a check fails — so you find out about downtime before your customers do.
How does uptime monitoring work?
Uptura sends a request to each URL or endpoint you add, on a schedule (as often as every 5 minutes during beta), and checks the response. You can require a specific status code or assert that the response contains a keyword, so a 200 that quietly serves an error page still counts as down. If a check fails, it's re-verified across consecutive checks to rule out a network blip, and then you're alerted — with the failing check and a recovery notification when it comes back.
What is a good uptime percentage?
99.9% uptime — often called 'three nines' — is a common target and allows roughly 43 minutes of downtime a month. Higher tiers like 99.99% ('four nines') allow only about 4 minutes. Uptura tracks your uptime percentage over time so you can hold yourself, or a vendor, to a specific SLA.
How often should a website be checked?
Checking every one to five minutes is the sweet spot for most business-critical sites — frequent enough to catch outages fast without generating noise. Uptura lets you tune the interval per monitor (as often as every 5 minutes during beta), so a marketing page and a checkout API can be watched at different cadences.
Is there a free uptime monitoring tool?
Yes. Uptura offers uptime monitoring free during our public beta — no credit card required. Create an account, add your sites, and Uptura checks them on a schedule and alerts you the moment one goes down, all from one dashboard.
How is uptime monitoring different from synthetic monitoring?
Uptime monitoring confirms a page or endpoint responds. Synthetic monitoring goes a step further and replays a whole user journey — like login or checkout — to confirm it actually works. They complement each other, and Uptura offers both from the same dashboard.
