Complete Website Monitoring Suite
GoScreenAPI checks your websites every 30 seconds using multiple protocols. Detect downtime before your users do, with double-verification to eliminate false positives.
HTTP / HTTPS Checks
Monitor any URL with GET, HEAD, POST, PUT, or DELETE methods. Validate status codes, response body with regex, and use basic authentication for protected endpoints.
Ping Monitoring
ICMP ping checks measure raw network reachability and latency. Ideal for servers, routers, and infrastructure that do not expose HTTP endpoints.
Port Monitoring
Verify that specific TCP ports are open and accepting connections. Monitor databases (3306, 5432), mail servers (25, 587), or any custom service port.
Keyword & Regex Checks
Go beyond status codes. Validate that your page contains (or does not contain) specific text or patterns. Catch content delivery failures and defacement instantly.
Heartbeat (Cron) Monitoring
Your scheduled jobs ping a unique URL. If a heartbeat is missed, you get alerted. Perfect for cron jobs, queue workers, and background tasks.
PageSpeed Insights (PSI)
Automated Lighthouse performance scores tracked over time. Get alerted when your Core Web Vitals drop below your defined thresholds.
30-Second Check Intervals
Most monitoring services check every 5 minutes. GoScreenAPI checks as frequently as every 30 seconds, meaning you detect outages up to 10x faster. Combined with double-verification from a secondary node, you get reliable alerts without false positives.
V2 Features That Set Us Apart
Why Uptime Monitoring Matters
Every minute of downtime costs money and erodes user trust. Studies show that even a single hour of unplanned downtime can cost small businesses thousands in lost revenue, while enterprise companies face losses in the hundreds of thousands. Beyond direct revenue impact, downtime damages SEO rankings, increases bounce rates, and drives customers to competitors.
GoScreenAPI's website uptime monitoring gives you peace of mind with continuous checks from multiple locations. Our double-verification system ensures you only get alerted for real incidents, not network blips. When something does go wrong, you will know within seconds — not minutes — giving your team the fastest possible response time.
Whether you are monitoring a single landing page or hundreds of microservices, our platform scales with you. Use tags to organize monitors by project, environment, or team. Bulk import lets you onboard entire infrastructures in seconds. And with detailed response time charts and uptime heatmaps, you always have the data you need for SLA reporting and performance optimization.
