HTTP and HTTPS monitoring
Monitor public websites and APIs with response status, elapsed response time, redirect handling, timeout controls, expected status codes, request methods, custom headers, and request bodies where your plan enables them.
DNS, ping, and TCP checks
Cover more than browser pages. Monitor DNS resolution, host reachability, and TCP services so the signal matches the dependency you need to understand.
Failure and recovery confirmation
Reduce noise with configurable consecutive-failure and consecutive-success thresholds. IsItUp records incidents as they open, continue, and recover.
Response-time and SSL signals
Set response-time alert thresholds and monitor SSL certificate expiry. Domain expiration monitoring is also available where enabled for the account.
Screenshots and visual evidence
Capture website screenshots through the isolated browser worker where enabled. A capture failure is reported separately from website availability.
Notifications and integrations
Configure email notifications and, where available to your plan, webhook destinations and additional notification channels. Maintenance windows help suppress expected work.
History, analytics, and exports
Review uptime, incidents, response-time behavior, percentiles, and report periods. CSV, PDF, snapshots, and scheduled reports are plan-controlled features.
API access and teams
Use scoped API tokens for monitor and incident workflows. Team and role-based access, public status pages, and other integrations are available only when enabled.
