Monitors

A monitor is a single check that runs on a schedule and tells you whether one specific thing is healthy. UptimeStatus groups related monitors under a site — a site is the thing you care about (an app, an API, a marketing page), and it can hold many monitors at once.

That means one site can have an Uptime check on its homepage, a Health Check on its API, an SSL check on its certificate, and a DNS check on its records — all reporting into the same place, the same incident timeline, and the same status page. Most monitors run from multiple regions with consensus, as often as every 30 seconds, and every one can attach notifications.

Availability

Is it up and reachable right now?

Uptime — HTTP(S) checks with status-code, latency, and keyword assertions.
Ping — ICMP reachability for hosts that don't speak HTTP.
TCP Port — confirm a port accepts connections (databases, SMTP, custom services).
Cron & Heartbeats — watch scheduled jobs by expecting a ping on a cadence.
Health Checks — fetch a JSON health endpoint and assert on individual fields.

Certificates & DNS

Is the domain layer correct and not about to lapse?

SSL — certificate-expiry warnings at 30/14/7/1 days and fingerprint-change detection.
Domains — WHOIS-based domain-registration expiry warnings.
DNS — snapshot A/AAAA/MX/TXT/NS/CAA records and alert on any change.
DNS Blocklist — watch your true origin IP against public blocklists.

Performance & security

Is it fast, well-built, and not leaking attack surface?

Performance — track response-time trends and catch slow regressions.
Lighthouse — scheduled Lighthouse audits with score-regression alerts.
Broken Links — crawl a site for broken links and mixed content.
Port Scan — detect newly exposed ports on your servers.
Server Metrics — push CPU/RAM/disk telemetry from your box.
AI Checks — describe an assertion in plain language and let AI verify it.
