Uptime that tells you in a minute
We request your pages every minute and confirm a failure with a second check before alerting you, so you get real outages, not noise.
Website monitoring and security
Know when your website is down, expired, or hacked.
ServerMonitor watches uptime, SSL certificates, domain registration and the content of your pages for malware and spam. You hear about a problem first, by email, Telegram, Slack or webhook.
Free for 3 sites. No credit card.
The three things that quietly cost you customers
A site that is down loses sales. An expired certificate scares visitors away with a browser warning. A hacked site loses trust and search ranking. Most owners find out from a customer.
Certificates and domains, before they lapse
Get warned weeks ahead when an SSL certificate or a domain registration is about to expire, with the exact date.
Malware, spam and hidden links
We look for injected scripts, hidden links, spam keywords, cloaked pages and listings on malware and phishing lists, and we alert you early.
