Built for

Whoever runs the site, MonitorAH watches it

Same product, same price, no per-seat fees. Pick the tier that fits the number of sites, not the number of teammates.

Developers

Ship faster knowing your APIs, deployments, and background jobs are watched. Bring monitors into source control via the REST API.

✓ Full /api/v1 surface for monitors, events, alerts, and status pages
✓ Heartbeat tokens for cron jobs and background workers

Agencies & MSPs

Monitor every client site from one account. Hand customers a branded status page and stop the “is the site down?” phone calls.

✓ Up to 500 monitors on the Agency tier
✓ Public status pages with a custom slug per client

Internal IT & DevOps

Watch the things that page you in the middle of the night. SSL renewals, domain expiries, and ports that shouldn’t be exposed — all from one dashboard.

✓ Slack, Discord, Telegram, and signed-webhook alerts
✓ PORT monitors with “alert if open” for security hygiene

Small businesses

Know if your site goes down before customers do. No DevOps team required — sign up, add a URL, get an email when something breaks.

✓ Free forever for 3 monitors with 5-minute checks
✓ One-click email alerts, no Slack or webhook setup needed

Features

Everything you need to keep things up

Lightning-fast monitoring

Sub-15-second checks across HTTP, SSL, DNS, WHOIS, ports, and heartbeats. Built to catch things before your customers do.

Intelligent alerting

Email, Slack, Discord, Telegram, SMS, voice, PagerDuty, Opsgenie, Teams, and signed webhooks. On-call rotations with auto-escalation.

Public status pages

Bundle any set of monitors into a branded, public status page. Past 90 days of incidents at a glance.

Real WHOIS + SSL

Expiry warnings 7 days out for domains and 14 days out for SSL certificates. Never wake up to a lapsed renewal again.

API-first

Every dashboard action is a /api/v1 endpoint. Bring your own client, your own CI, your own runbook.

Heartbeat monitoring

Dead-man-switch for cron jobs and background workers. POST a heartbeat — get paged if it stops.

Blacklist surveillance

Continuously check your sending IPs against Spamhaus, Spamcop, Barracuda, and SORBS DNSBLs.

Powerful analytics

Uptime %, MTTR, and response-time charts. Drill into individual checks with full request/response detail.
