Uptime & APIs
Is it up, and does it answer correctly — from every region you assign.
Website Monitoring
Track uptime, response time, and page performance from every region you assign.
Advanced Website Monitoring
Regex assertions, forbidden keywords, and custom request headers and bodies — check what a page or API actually returns, including authenticated endpoints.
Ping Monitoring
ICMP checks for raw network reachability and latency tracking.
TCP Monitoring
Check that a host's port accepts connections, with connect time tracked from every region you assign.
Advanced TCP Monitoring
TCP over TLS plus send/expect validation — confirm a service actually answers correctly, not just that its port is open.
DNS Monitoring
Track DNS resolution and validate that returned records actually match the values you expect — catch a hijacked or silently changed record, not just a resolution failure.
Cron Job Monitoring
Inbound 'I'm alive' checks for cron jobs and background workers — alerts when a run goes missing, with every ping and each run's duration kept.
API Transaction Monitoring
Chain multiple HTTP requests — extract a value from one response, like a login token, and reuse it in the next.
Synthetic Monitoring
Script a real multi-step browser journey — navigate, click, fill, wait, and assert — for user-flow monitoring beyond a simple uptime check.
