Uptime & synthetic
monitoring for your whole stack

Canary9 continuously checks your websites, APIs, and the services behind them: HTTP, DNS, TCP, ping, and full browser flows. When something breaks, you get a clear signal and the context to act before customers notice.

Everything you need to monitor reliability

Multiple check types, global coverage, and clean alerts without the noise.

HTTP / HTTPS Monitoring

Verify status codes, response times, and body content from multiple global locations on your schedule.

TCP & Port Checks

Confirm ports are open and responding. Catch firewall regressions and service restarts instantly.

DNS Resolution

Monitor DNS propagation and detect misconfigurations before they cascade into full outages.

ICMP Ping

Low-level host reachability checks for servers, load balancers, and network appliances.

Fast Multi-Channel Alerts

Get notified via email, Slack, PagerDuty, or webhook the moment a check fails: no batching delays.

First-Class API

Manage monitors, incidents, and alerts programmatically. Built for GitOps and infrastructure-as-code workflows.

Every failure arrives with its own diagnosis

The moment a check goes down, the probe that saw it runs a five-stage diagnostic and attaches the result to the alert: DNS resolution, a hop-by-hop path to the port, port reachability, the TLS handshake and the raw response. Click a stage.

Up and running in minutes

No agents. No SDKs. No configuration files. Just endpoints and thresholds.

01

Add an endpoint

Point Canary9 at any URL, hostname, or IP. Configure check type, interval, and alert thresholds in under a minute.

02

Canary9 watches continuously

Global synthetic checks run on your schedule from multiple regions. Every failure is recorded with timing, headers, and error context.

03

Know before customers do

When a check fails, you get a clear alert immediately, with enough context to act on: what broke, where, and how bad.

Alerts with context you can act on

Every alert from Canary9 includes the check region, HTTP status, response time, error body, and a direct link to the incident timeline. You open it knowing exactly what broke, where, and when.

  • ✓ Region-specific failure isolation
  • ✓ Full response body capture on failure
  • ✓ Incident timeline with check-by-check history
  • ✓ Alert deduplication: one incident, one alert thread
