The silent failures

What simple monitoring tools miss

Progressive latency

Your API responds in 3 seconds instead of 200ms. Not a downtime, but your conversion rate drops. Perimon catches the degradation.

Certificate about to expire

In 2 weeks, your SSL certificate expires. Your visitors get a scary warning page. Perimon alerts you 30 days before.

Gradual performance drop

Your database is getting slow. Not dead, just degraded. Perimon alerts before your users notice.

Built for makers

Everything you need. Nothing more.

No agent to install

Just a URL. No processes on your server. No dependencies. No PaaS headaches.

Smart alerting

No false positives. Perimon double-checks before sending an alert. You only get real incidents.

Detailed metrics

Response time, latency histograms, hourly graphs. Everything you need to debug.

Full REST API

Add sites via API. Query your history. Integrate Perimon into your stack without friction.

vs. complex tools
