// free 1-minute uptime monitoring
Know the moment your site goes down.
Moni checks your websites and APIs every minute — free — with SSL expiry warnings, cron heartbeats and alerts that only tell you the root cause.
Everything included, even on the free plan
Checks every minute
HTTP and HEAD checks with your expected status code and timeout — on the free plan, not just paid ones.
SSL certificate expiry
Moni watches your certificates and warns you before they expire, so visitors never see a browser warning.
Cron & heartbeat monitoring
Your scheduled jobs ping a unique URL when they run. If a backup or cron job goes quiet, you hear about it.
Dependency-aware alerts
When a server or router goes down, you get one alert for the root cause — not fifty for everything behind it.
TCP, DNS & keyword checks
Check ports, DNS records and page content, not just URLs. Every check type is included on every plan.
Wall displays
A clean full-screen status board for your office TV or an iframe in another dashboard, shareable with a link.
Response-time history
Uptime percentage and latency trends over 24 hours, a week, a month or all time.
API-first, with MCP
Everything the app does is in the public REST API with live Swagger docs — plus an MCP server so AI agents can manage your monitors.
Questions, answered
- Is Moni really free?
- Yes. The free plan checks your sites every minute and includes every check type, email and webhook alerts, wall displays and the full API. No card required.
- How is Moni different from UptimeRobot?
- Moni's free plan checks every minute (UptimeRobot's free plan checks every 5), includes SSL expiry, cron heartbeats and TCP/DNS checks at no cost, and only alerts you about the root cause when several things fail at once.
- What is dependency-aware alerting?
- You tell Moni that a monitor depends on another — for example that your site depends on its server. If the server goes down, you get one alert for the server, and the dependent checks stay quiet until it recovers.
- Can I monitor cron jobs and backups?
- Yes. A heartbeat monitor gives you a unique URL; your job pings it when it finishes. If the pings stop, Moni alerts you.
- Does Moni have an API?
- Everything in Moni is API-first: the same REST API the app uses is public, documented with live Swagger, and there's an MCP server so AI assistants can create and manage monitors for you.
