Exclusive Feature

Know WHY your site went down — not just that it did

When your site goes down, Pulse Stack™ doesn't just send you an alert. It automatically connects to your server and runs real diagnostic checks — HTTP response, DNS resolution, SSL certificates, disk space, memory usage, nginx status, and more. You get actual server data, not generic troubleshooting tips.

  • Automatic server-level diagnostics via SSH or agent
  • 12 real-time checks run in parallel
  • Actual command output, not generic advice
  • Identifies the exact service or resource causing the issue
  • One-click re-run diagnostics anytime

Pulse Stack™ caught a critical outage at 3 AM before any of our customers noticed. Absolute lifesaver for our SRE team.
