Downtime costs revenue, customers, and reputation — and most businesses only find out about it when a customer complains. Xitoring makes sure you know first. Xitoring is an all-in-one monitoring platform that watches your servers, websites, and online services around the clock. If something slows down, breaks, or goes offline, the right person on your team is alerted within one minute — by email, SMS, phone call, WhatsApp, Slack, Microsoft Teams, or any of 20+ notification channels. Unlike enterprise monitoring suites that take weeks to deploy and require specialist training, Xitoring is running in minutes. One command installs the monitoring agent on any Linux or Windows server, and it automatically detects and monitors the software your business runs on — web servers, databases, containers, and more than 30 common services. No consultants, no configuration marathon. Xitoring includes built-in AI that answers questions about your infrastructure in plain English. Ask "why was the website slow yesterday?" or "which servers need more capacity?" and get answers based on your actual data — turning hours of technical investigation into a single question. It also connects to AI assistants like Claude through the Model Context Protocol (MCP), so your team's AI tools can check system health and manage monitoring automatically. Keep customers informed with a professional status page on your own domain, fully branded to your business. Track uptime commitments with SLA reports. Manage incidents from detection to resolution in one place, with iOS and Android apps so your team stays covered anywhere. Pricing is flat and predictable — no per-metric charges or usage surprises. Start free forever with 2 servers and 8 uptime checks, or take a 30-day free trial of any paid plan (from $4.99/month). Trusted by IT teams, MSPs, and growing businesses worldwide.
