Live status from 300+ locations
HostTracker checks your websites, APIs and servers from checkpoints around the world. It confirms a real outage in seconds, then alerts you by phone call, SMS, Slack, Telegram or webhook - wherever you'll actually see it.
Every minute, checkpoints near your customers open your site.
Track uptime, response time, incidents, SSL expiry and alerts in one place. Start simple, then add advanced checks when you need them. Every monitor keeps its own history: uptime performance data, response times by location and an error log for each incident. Scheduled uptime reports go out weekly or monthly, and a public status page shows the same numbers to your customers in real time.
Our uptime checker opens your pages like a real customer would. If it won't load - you are losing sales, often without ever knowing it.
Press Check - you'll see in seconds whether real people around the world can reach you.
Start 30-day trialNot just "is the page up?" - we watch the things that quietly cost you money. SSL certificate monitoring, for one, checks expiration, chain validity and revocation on every run. See every check in our website monitoring software.
"I've worked with this monitoring service for a long time, and my daily routine is no longer a problem. It quietly watches all my sites and lets me respond the moment something goes wrong."
Real reviews from our customers on Trustpilot.
A simple availability checker only tests whether a homepage responds. HostTracker watches everything that can actually hurt your business - pages, ports, APIs, transactions, SSL certificates, servers, domains, blacklist status and response time.
Transaction monitoring replays scripted workflows in a real browser: it opens the page, fills the login form, adds to the cart and completes checkout, so a broken step is caught before a customer hits it. It scales from one site to thousands of endpoints: import monitors in bulk, group them by tag, give clients or teammates their own sub-accounts, and drive everything through the API.
14 alert channels to reach you
Without uptime monitoring 7 hours down · found out last · from a customer
