The monitoring that warns you before your users do

Websites, APIs, SSL certificates, DNS and scheduled tasks monitored continuously. Alerts by email or SMS, before your users notice.

No credit card required

MoniTao is a monitoring tool for websites, APIs and scheduled tasks. It continuously checks that your services answer, that your SSL certificates are valid, that your DNS records have not changed, and that your scheduled tasks actually ran.

When something stops working, the alert goes out by email or SMS, before your customers notice. Nothing to install on your servers: monitoring runs from the outside, the way a visitor sees it.

01 — What goes down, and how you find out

Sound familiar?

Every minute counts when a service goes down. And often, you find out too late.

A customer tells you your site is down

You learn about the incident via email or social media. Bad image, trust damaged. And the problem might have been going on for hours.

Your backup cron hasn't run for 3 days

No alert, no log. You discover it the day you need to restore data. Too late.

SSL certificate expired: visitors see a warning

"This site is not secure". Your users flee, your SEO tanks. All for a forgotten renewal.

Someone changed your DNS without warning

IP change, failed migration or malicious act. Without monitoring, you'll only know too late.

02 — What MoniTao watches

MoniTao covers the entire availability chain

Those four situations map to four surfaces. Here is what MoniTao checks on each, and what sets off an alert.

HTTP / HTTPS Monitors
HTTP/HTTPS & API Monitoring
Check availability and response time of your sites and endpoints.
HTTP Code Detection
Get alerted if your page returns a 500, 404 or any abnormal code.
Content Validation
Verify specific text is present on the page (payment OK, version, etc.).
Response Time
Measure your page performance and detect slowdowns.
SSL/TLS Monitoring
Availability
Alert before certificate expiration. Never see "site not secure" again.
DNS Monitoring
Detect suspicious IP or DNS record changes.
Integrity
Expected content, HTTP codes validation
Heartbeat (Crons & Jobs)
Health Ping
Your script sends a ping after execution. No ping = alert.
Flexible Scheduling
Set expected interval: every 5 min, hourly, daily...
Late Detection
Configurable grace period before triggering an alert.
Alerts & Notifications
Multi-channel
Email and SMS (Business). Choose how to be alerted.
Smart Alerts

06 — What people ask us

Frequently asked questions about website monitoring

The questions that come up most often, answered briefly.

What exactly is Heartbeat? Heartbeat monitors your scheduled tasks (crons, backups, scripts). Your script sends a ping to MoniTao after each successful run. If the ping doesn't arrive on time, you get alerted.
How do SSL alerts work? MoniTao automatically checks SSL certificates on your HTTPS sites and alerts you X days before expiration (configurable). Never have an expired certificate again!
Is my data secure? Absolutely. We use mandatory HTTPS, strict security headers, CSRF protection, and only store what's necessary. Passwords are hashed with bcrypt.
Can I avoid false alerts during maintenance? Yes! Create a maintenance window to suspend alerts during your planned interventions.
