cerberops
Everything three heads can guard.
Cerberops is built around three monitor types and a long tail of features that make production observability boring — in a good way.
Each head guards a different threat
Most "ping tools" only see one thing — an HTTP 200. Cerberops watches three angles at once, because production breaks in three ways.
HTTP / API monitoring
Check any URL with full assertion library — status codes, headers, response body, latency budgets. Custom methods, headers, payloads.
SSL certificate watch
Get notified before certificates expire. Cerberops walks the chain, reads expiry dates, and raises alarm at the configurable threshold.
Heartbeat / cron jobs
Your nightly backup didn't run? Your worker stopped? Cerberops gives you a URL — ping it from cron and we'll alert when the pings stop.
Three heads, three blast radii.
HTTP, SSL, heartbeat — three completely different failure modes, three completely different alert paths. Most "uptime tools" only see HTTP 200s. Cerberops watches the angles they miss.
// cron stops firing → heartbeat head.
// 5xx returns 200 OK → HTTP head, with body assertions.
Everything you need, nothing you don't
Latency charts
p95 and p99 sparklines per monitor. Spot trends before they break the SLO.
Public status pages
One-click public page with custom slug. Embed an SVG status badge anywhere.
Maintenance windows
Schedule one-off or weekly downtime windows. Alerts suppress automatically.
Custom assertions
Match JSON paths, regex bodies, header values. Define exactly what "healthy" means.
Webhooks + Slack
Generic webhook drivers + native Slack channel attach. Hook into PagerDuty, OpsGenie, Discord.
REST API + tokens
Personal tokens, read-only API for dashboards, CI integrations, custom tooling.
Teams + roles
Invite teammates, owner / member roles, per-channel routing. SOC-friendly audit log.
Monthly reports
Uptime percentages, MTTR, incident timelines — every month, in your inbox.
Smart deduping
Configurable failure threshold. We alert when it's real, not when the network blinks.
Production never sleeps.
Neither does Cerberus.
Every check runs from our queue every 60 seconds, around the clock. Maintenance windows mute alerts without stopping the data. Smart deduplication kills flap noise before it ever hits your inbox.
One eye on the API. One on the certs. One on the cron.
A guardian, not a ping bot
Most uptime tools only know how to fire HTTP requests and shout "200 OK!" at the wind. Here's what Cerberops does differently.
| Capability | Cerberops | Generic ping tools |
|---|---|---|
| SSL certificate expiry watch | ✓ first-class monitor type | — add-on, or none |
| Heartbeat / cron monitoring | ✓ built in, unique URLs | — separate product |
| Body / header assertions | ✓ regex, JSON path, exact | status-code only |
| Public status pages | ✓ included free | paid add-on |
| Maintenance windows | ✓ one-off + recurring | manual mute |
| REST API + tokens | ✓ from free tier | enterprise only |
