SonarOps

I built SonarOps because every monitoring tool I tried told me a site was down — never why. So I built the one I wanted. It checks your sites every 60 seconds from probes in the EU and USA. When one probe sees an outage, a second probe in another region confirms it before I page you, so a local network blip doesn't wake you at 3am. That cross-check costs a second or two of detection delay. I think it's worth it. Beyond up/down, SonarOps shows where the time goes: DNS, TLS handshake, first byte, full load. SSL Sentinel tracks certificate expiry with reminders at 60, 30, 14 and 7 days and full chain validation, not just the leaf. Deep Scan crawls your site for broken links. Alerts go to email, Telegram or webhook, with a cooldown so you get signal, not spam. One developer, no VC.
