Deployment

mold supports multiple deployment modes; from a single GPU machine to cloud GPU providers.

Remote Rendering

The simplest setup: run the server on a GPU host, generate from anywhere.

# On your GPU server
mold serve

# From your laptop
MOLD_HOST=http://gpu-server:7680 mold run "a cat"

Deployment Options

Method	Best For
Docker & RunPod	Cloud GPUs, RunPod pods
mold runpod CLI	Integrated pod and volume control
mold lambda CLI	Private Lambda Cloud web UI
HTTPS reverse relay	Access an existing machine from anywhere
NixOS	NixOS systems, declarative setup
Systemd service	Any Linux with NVIDIA GPU

Systemd Service

Two sample units ship in contrib/. Pick one.

System-wide (contrib/mold-server.service), for a dedicated service user:

sudo cp contrib/mold-server.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now mold-server

User mode (contrib/mold-server.user.service), for a single-user GPU box:

cp contrib/mold-server.user.service ~/.config/systemd/user/mold-server.service
sudo loginctl enable-linger "$USER"   # survive logout; once per box
systemctl --user daemon-reload
systemctl --user enable --now mold-server

Key settings:

ExecStart=/usr/local/bin/mold serve --port 7680 --bind 0.0.0.0
