Quick Start (Ubuntu Server)

1. Build the Binary

Clone and build the single binary on any machine with Go & Node.js:

git clone https://github.com/yourusername/caddytor.git
cd caddytor
make build-linux

The output file is bin/caddytor-linux-amd64.

2. Copy to Your Server

Copy the binary and systemd service to your Ubuntu VPS:

# Copy binary
sudo mkdir -p /opt/caddytor
sudo cp bin/caddytor-linux-amd64 /opt/caddytor/caddytor
sudo chmod +x /opt/caddytor/caddytor

# Copy service
sudo cp scripts/caddytor.service /etc/systemd/system/

3. Start Service

sudo systemctl daemon-reload
sudo systemctl enable --now caddytor

Open http://YOUR_SERVER_OR_WIREGUARD_IP:8080 in your browser.

Configure options using environment variables or a .env file:

Variable	Default	Description

`FS_ROOT`	`/` (or `.` on Win)	Root scope path for the File Manager

Local Development (Windows / macOS / Linux)

You can run Caddytor locally. On non-Linux machines, simulated metrics are generated automatically:

# Terminal 1: Start Go Backend
go run ./cmd/caddytor

# Terminal 2: Start Frontend with Live Reload
cd web
npm install
npm run dev

Open http://localhost:5173.
