Server monitoring · private beta

Your servers,
quietly watched.

Towamori keeps an eye on your servers and VPSs — CPU, memory, disks and network — through an open-source agent small enough to read in an afternoon.

$ curl -fsSL https://app.towamori.com/install.sh | sudo TOWAMORI_TOKEN=your-token sh

towa 永遠 — always. mori 守り — to watch over.

Paste the install line, and the server shows up with live CPU, memory, load, disk and network charts within seconds.

For indie developers, VPS owners and small teams who want to know what their machines are doing without running a monitoring stack.

Designed with Tokyo, Seoul and Singapore in mind. Uptime checks from probes in the region are next on the list.

An agent you can trust on your server

You are installing a program that runs all the time. Here is exactly what it can and cannot do — and the code is Apache-2.0, so you can check.

Outbound only. It never listens on a port.
No remote control. It never runs commands, opens a shell or touches files. The platform can only change how often it reports.
No root. It runs as a throwaway unprivileged user with a read-only view of the system.
Numbers, not data. Counters and a few facts about the machine. No process names, command lines, files or logs.
See it first. towamori-agent --once prints everything it would ever send.
No dependencies. Go standard library only — about 1,700 lines.
