// what's in the box

The whole kit. Not an upsell ladder.

[01]
Five check types
HTTP(S), TCP, ping, DNS, and push. Assert status codes, response bodies, latency, keyword matches. Works whether you're watching a public API or a box on your LAN.
monitor: api.acme.io
type: http
interval: 20s
expect: status 200
[02]
SSL certificate monitoring
Every HTTPS monitor tracks its cert automatically. Beacon alerts you when a cert gets close to expiry — 30, 14, and 3 days out. No more surprises at 2am.
cert: *.acme.io
expires: 2026-07-14
issuer: Let's Encrypt
chain: valid
[03]
Public status pages
One click to publish a status page per group of monitors. Custom domain, custom branding, logo, favicon, and custom CSS. Incident history included.
status.acme.io
├─ api up
├─ web up
└─ workers degraded
[04]
Teams & roles
Owner, Admin, Member, Viewer. Every monitor change goes into an audit log. Maintenance windows suppress alerts for scheduled work.
role: admin
audit: on
windows: 3 scheduled
[05]
Notifications
Email, Slack, Discord, Telegram, and signed webhooks. HMAC-SHA256 on every webhook, custom headers, your choice of target.
slack → #incidents
email → oncall@acme.io
webhook → HMAC-SHA256
[06]
Organized monitoring
Tags, groups, search, and bulk actions. Pause, resume, or delete fifty monitors at once. Export to JSON; import somewhere else.
tags: [prod, edge]
group: billing
bulk: pause 12 →
// an incident looks like this

From ping to page in 2.8 seconds.

Heartbeat fails → retry → confirm DOWN → fan out to every channel you've wired up. Broadcast over WebSockets so the dashboard updates live.
