Xitoring
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.

upsonar.io
Unlike many uptime monitoring tools that merely check server responses, upsonar enhances the process by fully loading your website to uncover all external elements such as CDN-hosted resources, third-party scripts, web fonts, and API endpoints. If any of these components encounter issues, you receive prompt notifications, allowing you to resolve the problems before they affect your users.
Moreover, it conducts availability assessments from various locations across the globe at the same time, which is crucial for detecting any regional CDN failures or localized outages that might otherwise go unnoticed. On top of uptime monitoring, upsonar also tracks SSL certificate expirations, monitors domain expiration dates to prevent renewal snags, and identifies changes in DNS records that may indicate unauthorized modifications.
The five distinct monitoring types work in harmony within a single dashboard, providing a comprehensive overview of your website's health. Notifications can be dispatched via email, Telegram, or webhooks that integrate effortlessly with services like Slack, Discord, and PagerDuty. You can start with a free plan that supports monitoring for three websites, offering all features without requiring a credit card, which allows you to fully explore its advantages without any risk. This way, you can ensure your online presence remains robust and reliable while keeping your users satisfied.
