Setup took 30 seconds. I got an SSL expiry alert that saved me from downtime the very next week.

Simple, reliable, and affordable. I monitor three client sites and the alerts are always on time.

The passwordless dashboard is genius. No more forgotten credentials — just a bookmarked link.

Daily uptime — last 30 days
Enter your domain and email above. We'll send a verification link to confirm ownership. Once verified, monitoring starts immediately — DNS, SSL, HTTP status, and content changes, checked every hour.
Your domain is monitored free for 30 days. You'll get email alerts for any downtime, SSL issues, or content changes. Before the trial ends, subscribe for $1/month or $10/year to keep monitoring active.
After verification you'll receive a unique access key by email. No passwords to remember — just bookmark your dashboard link. The key is generated cryptographically and checked with constant-time comparison, so it's actually more secure than a typical password.
The entire monitor is a single native binary compiled from Rust — memory-safe, no garbage collector pauses, no runtime interpreter. Starts in milliseconds, uses minimal resources.
We run two independent instances monitoring the same domains. If one goes down, the other keeps checking and alerting. You're covered even during our own maintenance.
Data is stored in CSV files and logs as JSONL logs. No database complexity, no migrations to break. Simplicity that survives anything.
The core monitoring engine is open source. Audit the code, run your own instance, or contribute. Transparency is the foundation of trust.
