Why Teams Choose UptimeMonke
No artificial paywalls, no bloated enterprise contracts. Just fast, dependable infrastructure monitoring.
Sub-Minute Edge Checks
Traditional monitoring platforms lock free accounts to 5-minute intervals. UptimeMonke lets you run sub-minute checks right out of the box so you know about failures instantly.
SSRF-Hardened Cloud Fleet
Engineered with strict RFC1918 link-local defense, AWS IMDSv2 metadata attack prevention, and DNS rebinding guards. Safe for corporate internal targets.
Branded Public Status Pages
Publish a clean status page at /status/:slug with 90-day historical uptime bars and active incident feeds. Keeps your customers informed during outages.
Multi-Channel Alerts
Deliver alerts to Slack, Discord, Telegram, custom Webhooks, and Mailgun emails with zero configuration pain. Verified contacts prevent alert spoofing.
There Is No Paid Plan
Every single feature works on a free account — all check types, sub-minute intervals, public status pages, and alerting. What an optional donation pays for is capacity, because that is the only part that costs real server resources.
Ten monitors at one minute. Or fifty at five minutes. Or one at six seconds — it is the exact same compute load, so it is the exact same free price.
Around a month of twenty monitors at one minute, or ten at thirty seconds. Unused capacity rolls over with zero subscriptions — buy another whenever you run low.
Sign-in first, so capacity lands on your workspace rather than disappearing.
A week of grace at full capacity, then a seamless fallback to the free 14,400 daily allowance. Your monitors keep running throughout.
Why checks and not monitors? A five-second check is twelve times the work of a one-minute one. Charging per monitor would price those the same — and it would stop a free account running a single fast check that costs no more than ten slow ones.
Everything You Need to Know
Honest answers to common developer questions about UptimeMonke.
Is UptimeMonke really free? Do I need a credit card?
Yes! Every account receives 14,400 free checks every single day forever. No credit card is ever required. You can monitor 10 endpoints at 1-minute intervals or 50 endpoints at 5-minute intervals completely free.
How is UptimeMonke different from traditional tools like UptimeRobot?
Legacy monitoring services restrict free accounts to slow 5-minute check intervals and paywall critical features like SSL certificate expiry warnings and cron heartbeat monitoring behind monthly recurring subscriptions. UptimeMonke provides sub-minute intervals, SSL tracking, heartbeats, and public status pages on the free tier, supported by optional one-off $2.99 coffee donations instead of subscriptions.
Where are monitoring probes dispatched from?
Probes originate from hardened AWS Lightsail edge instances (currently in Singapore ap-southeast-1a). Our probe engine runs with HTTP keep-alive disabled to measure genuine first-packet connection times (DNS + TCP handshake + TLS) just like real visitors experience.
What happens if my workspace runs out of donated credit?
Your monitors are never paused or deleted. When your credit reaches zero, you enter a 7-day grace window at full service, after which your workspace smoothly transitions back to the 14,400 daily free allowance. Existing monitors continue checking uninterrupted.
Can I create a public status page for my clients or users?
Yes. Every workspace has an instantly shareable public status page at /status/:slug. It features real-time 90-day uptime bars, overall operational status, and automated incident logs with sensitive target URLs safely withheld.
