Server monitoring, one script away.
One lightweight script. Complete visibility into CPU, memory, disk, and network. See what's happening on your servers right now—and what happened 24 hours ago.
Everything you need, nothing you don't
Lightweight monitoring that respects your server's resources.
One-Line Install
No complex configuration. Run our install script and the agent starts reporting immediately. Takes 30 seconds, not 30 minutes.
Minimal Resource Usage
Our agent uses less than 1% CPU and minimal memory. You won't even know it's there—except when you need the data.
Real-Time & History
See live metrics updating every minute. Scroll back through 24 hours of history to spot trends and investigate issues.
Interactive Charts
Beautiful, responsive charts for all metrics. Zoom, pan, and inspect data points. Export or share with your team.
Works Anywhere
VPS, dedicated servers, cloud instances, Raspberry Pi. If it runs Linux, we can monitor it. No firewall rules needed.
Secure by Design
The agent only sends metrics outbound—no open ports, no inbound connections. Your server's security stays intact.

Frequently asked questions
Everything you need to know about Server Monitoring.
Absolutely. Monitor one server, completely free. No credit card, no trial period. We believe infrastructure monitoring should be accessible to everyone. More features are available in our paid plans.
Any modern Linux distribution: Ubuntu, Debian, CentOS, Rocky Linux, AlmaLinux, Fedora, Arch, and more. If it has bash and curl, the agent will work.
The agent is extremely lightweight—typically using less than 1% CPU and under 20MB of RAM. It collects metrics every minute and sends them via a single HTTPS request. You won't notice it's running.
Nope! The agent makes outbound HTTPS connections only (like a web browser). No inbound ports needed, no firewall rules to configure. It works behind NAT, on VPSs, and in restricted environments.
We keep 24 hours of per-minute metrics on the free plan. This gives you a full day's view to spot trends and investigate issues. Longer retention may be available in future plans.
