What is upsonar.io?

UPSONAR.IO is an uptime monitoring service with a unique approach: we don't just ping your server - we parse your HTML and verify every external dependency.

The Problem We Solve: Your website can return "200 OK" while being completely broken for users. Why? Because modern sites depend on CDNs, Google Fonts, analytics scripts, payment widgets, and other third-party resources. When these fail, traditional monitors stay silent.

How Upsonar is Different:

  • Dependency Analysis: We parse your page and check every script, stylesheet, font, and image - including those hosted externally
  • Multi-Region Checks: Monitor from multiple global locations to catch regional outages
  • SSL Certificate Monitoring: Get alerts before your certificates expire
  • Smart Notifications: Email, Telegram, and webhooks with cooldown periods

Best For:

  • WordPress and CMS sites with themes using external assets
  • Landing pages with CDN-hosted resources
  • E-commerce sites using payment widgets
  • Server-rendered apps (Next.js, Nuxt)
