Telegram alerts

Get notified on your phone the moment a site goes down. Configure your own bot — your token, your privacy.

⏱

Response time tracking

Not just up/down. Know if your site is Very Fast (<1.5s), Fast, Slow, or Very Slow before visitors notice.

🔄

3-pass verification

Transient blips don't page you. We retry 3 times before declaring a site down and sending any alert.

📊

Visual timeline

Color-coded 30-min (7d) or 5-min (24h) buckets show you exactly when and how long an incident lasted.

🔒

REST API

Pull uptime data into your own dashboards, Grafana, CI pipelines, or scripts with a simple API key.

📧

Email fallback

No Telegram? Alerts fall back to email automatically so you never miss a critical event.

🔔

Smart alerting — not alert fatigue

Alerts are sent once per incident, grouped per account. If 3 of your sites go down at the same time, you get one Telegram message with all three — not three separate pings at 3am.

Up and running in 2 minutes
No agents to install. No DNS changes. Just add your URLs.

Create a free account

Paste your URLs

Add one URL per line in your profile. HTTP and HTTPS both supported. Comments with # allowed.

Optional but recommended. Paste your bot token and chat ID — alerts land directly in your Telegram.

Within 5 minutes you'll see your first check results. View 1-day, 7-day, or 30-day history anytime.

Response time tiers
We track four speed levels — not just pass/fail.
StatusResponse timeWhat it means
Very Fast< 1.5 sExcellent — users won't notice any delay
Fast1.5 – 3 sGood — acceptable for most web apps
Slow3 – 5 sDegraded — users may notice; investigate
Very Slow> 5 sCritical degradation — act immediately
Down—Request failed after 3 retries over 60 s
REST API
Integrate uptime data anywhere with one HTTP call.
