We check. You get notified. That's it.
Engineered for high-load. Precise uptime tracking with millisecond accuracy.

No more false alarms.
No more silent outages.

Most monitoring tools force you into a bad compromise. You either get spammed with alerts for every one-second network blip, or you set the check interval to 5 minutes and find out your checkout is broken from angry customer support tickets.

We built our engine to respect your attention. It checks your infrastructure continuously. But the moment an error occurs, it doesn't panic. Instead, it instantly triggers a rapid series of verification checks from an isolated queue.

You only get alerted when the downtime is real. No noise, no panic, just absolute precision.

Welcome to the new standard of uptime tracking.

All infrastructure on one screen

No visual noise. Only statuses, uptime, and response times of your resources.

Frequently Asked Questions

Everything you need to know about our monitoring service.

Is there a free plan?

Yes, our basic plan is completely free and includes everything you need for personal projects: up to 10 endpoints, 60-second intervals, and instant notifications. For business needs, we offer a Pro plan with advanced features.

What is the minimum check interval?

You can set up a monitoring interval starting from 10 seconds on the Pro plan, and 60 seconds on the basic plan. This incredibly high frequency, combined with instant notifications, allows you to respond to any issues almost immediately, before your users even notice.

Which protocols and request settings are supported?

We support HTTP and HTTPS protocols. For flexible API monitoring, all standard HTTP methods are available: GET, POST, PUT, PATCH, OPTIONS, DELETE, HEAD. You can configure the expected response codes (e.g., 200, 201, or 401) and set a custom timeout up to 30 seconds for heavy endpoints.

How does the false alarm protection work?

Our engine uses a full-fledged State machine. If the server doesn't respond, we initiate a series of rapid retries outside the main schedule. A notification is sent to you only if the predefined error threshold (DOWN) is reached. The same applies to recovery (UP) — we ensure your server is responding stably before closing the incident and delivering the good news.

Is the downtime history saved?

Yes. The system automatically opens an incident upon a confirmed resource failure and records the exact time. When the status recovers, the incident is closed, and we calculate the downtime duration to the second. The entire history is available on the monitor's analytics page.

Is Telegram login secure?

Absolutely. The entire authorization process takes place on official Telegram servers. We do not gain access to your account, passwords, or personal messages. Telegram only shares your public ID and name with us, so we can create a profile and send you notifications about your site statuses.
