What Down Device is
Down Device is a web-based monitoring service for websites, web applications, REST APIs, SSL certificates, domains, ports, network devices, and DNS. It checks services from multiple locations using distributed monitoring nodes. API checks can use custom headers, validate content, and track response times. SSL monitoring validates the certificate chain and sends expiry alerts at 30, 14, and 7 days. DNS monitoring follows record changes, accounts for TTL changes to reduce noise, and discovers subdomains through Certificate Transparency logs. The Free plan covers five devices with HTTP and ping checks at five-minute intervals and email alerts; API, SNMP, and port monitoring are excluded. Basic is $9 per month, Pro is $22.50 per month, and Enterprise is $45 per month, with different device capacities, check intervals, monitoring types, retention, and alert options. Multiple admins, customizable roles, and granular team permissions support shared administration. The Enterprise tier lists custom integrations, though the pricing page names no integrations.
