Know when your site actually breaks·upsonar.io

upsonar.io is a website monitoring service that checks uptime, SSL certificates, DNS records, domain expiration, and every external dependency (CDNs, fonts, scripts, APIs) a page loads, from a network of 8 global locations across 3 continents. It sends alerts via email, Telegram, Slack, or webhook when something breaks, and can automatically create incidents and public status pages. The service is designed to catch failures that traditional uptime monitors miss, such as a page returning 200 OK while a third-party resource is broken.
