Know when your site goes down.
Before anyone else does.
ServerVisor checks your websites, APIs, and services from multiple locations. The moment something fails, your team gets an alert — via Slack, SMS, email, or wherever you work.
Everything you need to stay ahead of downtime.
HTTP uptime checks
Monitor any URL — your homepage, API endpoints, checkout flows, admin panels. Check as often as every minute.
SSL certificate monitoring
We track expiry dates and alert you well before a certificate lapses — before browsers start warning your visitors.
Domain expiry alerts
A lapsed domain can take your whole business offline. ServerVisor watches renewal dates and gives you plenty of warning.
Heartbeat monitoring
Set up a heartbeat URL and ping it at the end of your cron job or script. If the pings stop arriving, you get alerted right away.
Multi-location checks
Checks run from multiple regions so you can tell the difference between a real outage and a local network blip.
Instant multi-channel alerts
Route alerts to Slack, Teams, Discord, email, SMS, push, or webhooks — so they land where your team actually looks.
Monitor tiers that fit your needs.
Every monitor uses a slot from one of four tiers. Your plan determines what's included, and you can add more slots at any time.
Free Monitor 24 hours
The free plan includes 3 Free Monitor slots, no card required. When you upgrade to a paid plan, they convert to Basic Monitors.
Basic Monitor 60 min
Checks every 60 minutes. The most affordable tier, for sites where knowing within the hour is fast enough.
Pro Monitor 15 min
Checks every 15 minutes. A balance between cost and response time, for sites where hourly checks aren't quite enough.
Business Monitor 1 min · heartbeat
Checks every minute. When downtime costs money, faster detection means a faster fix. Can also be configured as heartbeat monitors that listen for pings from your scripts and cron jobs.
No agents. No code changes.
Choose a monitor type, enter a URL or address, set a check interval, and pick your alert channels. That's it.
Add a URL
Enter the site or service you want to watch. Pick a check interval — as frequent as every minute.
Choose what to watch
SSL and domain expiry monitoring are included free with any HTTP check — just tick a box to enable them.
Connect your alerts
Pick the channels your team uses — Slack, email, SMS, whatever. Incidents go straight there.
Be first to know
When something fails, you hear about it before your customers, your boss, or anyone else does.
Start monitoring before the next surprise.
No agents, no code changes. No credit card required to get started.

Node Insights tracks custom facts reported by your scripts — version numbers, disk usage, config values, anything a script can output. You'll know what changed across your machines, not just what went down.
