Down Device is a web-based monitoring service for websites, web applications, REST APIs, SSL certificates, domains, ports, network devices, and DNS. It checks from multiple locations using distributed monitoring nodes. API monitors can send custom headers, validate content, and track response times. SSL monitoring validates the full certificate chain and provides expiry alerts at 30, 14, and 7 days. DNS monitoring tracks record changes, adjusts for TTL changes to reduce noise, and discovers subdomains through Certificate Transparency logs. The Free plan covers five devices with HTTP and ping checks every five minutes and email alerts. Basic, at $9.00 USD per month, includes 25–50 devices, 60-second checks, API and SNMP monitoring, port checks, and 30-day retention. Pro is $22.50 USD per month for 100 devices, all monitoring types, 30-second checks, and 90-day retention. Enterprise costs $45.00 USD per month and checks every 15 seconds, with priority support, custom integrations, white-label options, and one-year retention. The service supports multiple admins, customizable roles, and granular team permissions.
