Comprehensive monitoring
Monitor every layer of your stack
HTTP, TCP, DNS, Ping, heartbeat, and SSL — all from one platform with checks from US, EU, and APAC regions.
- Uptime Monitoring
- Check your sites every minute from multiple global locations. HTTP/HTTPS with custom headers, keyword validation, and consecutive-check confirmation to avoid false positives.
- Infrastructure Monitoring
- Go beyond HTTP. Monitor TCP ports (databases, Redis, SMTP), verify DNS records (A, AAAA, CNAME, MX, TXT), and test host reachability with Ping/ICMP — all on every plan.
- Heartbeat & Cron
- Your services ping a unique URL on schedule. If a ping is missed, you get alerted. Perfect for cron jobs, background workers, and scheduled tasks.
- SSL Expiry Alerts
- Get alerts 30, 14, 7, and 1 day before your SSL certificates expire. Certificate chain validation and issuer tracking included on all plans.
- Response Time Tracking
- Track avg, min, and max response times with 30-day and 1-year charts. Spot slowdowns before they hurt conversions.
- Multi-region Checks
- Checks run from US, EU, and APAC. A failure must be confirmed from multiple regions before triggering an alert.
Smart alerting
Intelligent alerts, less noise
Configurable thresholds, anomaly detection, flap suppression, and alert correlation — so you get one actionable notification, not a flood of noise.
- Response time alerts
- Set custom ms thresholds with consecutive-check validation. One alert per slow period, not per check. Starter
- Anomaly detection
- Learns your 7-day baseline and alerts on statistical deviations using Z-score analysis. Business
- Flap detection
- Automatically suppresses rapid up/down transitions so you aren't paged during intermittent blips. Business
- Alert correlation
- Groups simultaneous failures within a 60-second window into a single notification. Business

Customer-facing
Turn outages into trust
Branded status pages show your customers you're on top of things — reducing support tickets and building confidence during incidents.
- Branded pages
- Your logo, colors, and custom domain (status.yourdomain.com). Looks like your product, not a third-party tool.
- Subscriber notifications
- Customers subscribe to updates via email. They hear about incidents from you, not Twitter.
- Real-time sync
- Status pages update automatically from your monitor data. No manual toggles needed.
- Uptime badges
- Embed shields.io-style badges in your README or docs. 24h, 7d, or 30d periods with copy-paste snippets.
Incident management
Manage incidents & maintenance
Create incidents with status updates and timelines. Schedule maintenance windows that automatically pause alerts during deploys.
- Incident timelines
- Post updates as you investigate and resolve. Subscribers are notified automatically at each stage. Starter
- Maintenance windows
- Schedule windows in advance. Linked monitors are treated as "in maintenance" during the window — no false alerts. Starter
- Auto-create from monitors
- Incidents are created automatically when a monitor goes down, or manually from the dashboard.
