vpsmon: A 5MB Go-based system monitor for Linux VPS

Lightweight system monitor for Linux VPS written in Go

vpsmon is a lightweight system monitor for Linux VPS, written in Go. It runs as a single binary using only ~5MB of RAM and provides a web UI with login that auto-refreshes every 5 seconds. It tracks CPU, memory, swap, disk, network, uptime, and process count. Installation is streamlined via a one-liner script or a deploy script that sets up a systemd service on port 8088. Passwords are stored as bcrypt hashes, and the tool is designed for minimal resource usage on small servers.
