UptimeKeeper is a freemium web service for monitoring websites, APIs, and ports globally. It tracks connection time, time to first byte, and full page-load speed, while checking SSL expiry, invalid certificate chains, domain renewals, keywords, titles, and content changes. Downtime alerts can arrive by email or SMS, with repeat-frequency controls and maintenance pauses. Incidents record start and end times, duration, and descriptive causes such as timeouts, SSL errors, or DNS issues. Teams can publish branded, shareable status pages with selected metrics and embed them on a website. Page-speed tools provide real-time analysis, historical tracking, and reports on load times, bottlenecks, and optimization tips. Threshold alerts can use email, SMS, Slack, or webhooks, and APIs support workflow automation. Monitors are checked every minute. UptimeKeeper says setup takes less than 30 seconds. A free plan covers essential monitoring, while advanced SSL/domain monitoring and SMS alerts are paid features. Paid plans start at 7.00 USD per month; the company lists its address in London, UK.
