pzmod

Project Zomboid dedicated-server mod manager · this is how you modded.

pzmod is a keyboard-driven terminal app (plus a scriptable CLI) for managing the mods on a Project Zomboid dedicated server. It browses the Steam Workshop, resolves dependencies, orders your mods, validates everything before you boot the server, and keeps timestamped backups, all while preserving your servertest.ini byte-for-byte.

Features

• Terminal app: browse and manage everything from a fast, keyboard-driven UI
• Workshop search & browse: find mods and add them without copying IDs
• Dependency auto-resolution: pull in required items (and their deps) for you
• Load-order management: reorder mods and get a framework-first suggestion
• Type-to-filter: press / on any long list to filter instantly
• Dry-run validation: catch missing deps, unknown mod IDs, delisted items, and bad map order before launch
• Backups & rollback: every save snapshots the config; restore in one step
• Multiple server profiles: manage several configs from one place
• Build 41 / Build 42 awareness: per-profile build with compatibility hints
• Byte-exact config edits: comments, ordering, and line endings are preserved

Demo

Each clip is captioned with what it does. Filter a long list, get a load-order suggestion, validate before you boot, and snapshot every save:

Install

Linux & macOS

curl -fsSL https://pzmod.dev/install.sh | bash

Installs the latest release to /usr/local/bin (Intel and Apple Silicon), with the download checksum-verified. Pass a custom path with | bash -s -- ~/.local/bin/pzmod.

Prefer to read the script first?

curl -fsSL https://pzmod.dev/install.sh -o install.sh
less install.sh
bash install.sh        # optional: bash install.sh ~/.local/bin/pzmod

Windows (PowerShell)

irm https://pzmod.dev/install.ps1 | iex

Installs to %LOCALAPPDATA%\pzmod and adds it to your user PATH.

Docker

A minimal multi-arch image (amd64/arm64) is published to the GitHub Container Registry:

docker run --rm -it \
  -e PZMOD_STEAM_KEY=<key> \
  -v "$PWD:/data" \
  ghcr.io/kldzj/pzmod --file /data/servertest.ini validate

Pass your Steam key with PZMOD_STEAM_KEY and mount your config in. Add -v pzmod:/config to persist profiles and backups across runs.

Manual

Download a binary from the releases page.

Usage

# Launch the interactive terminal app (profile picker)
pzmod

# Open a specific config directly
pzmod --file path/to/servertest.ini

# Scriptable subcommands (use --file or --profile, or the default profile)
pzmod profile add --name "My Server" --file path/to/servertest.ini --build b41
pzmod set name "My Server"
pzmod get list
pzmod search hydrocraft
pzmod mods add 2392709985 --resolve-deps
pzmod mods show 2392709985 # print resolved details without adding
pzmod mods add 2392709985 --dry-run # preview what would be added, write nothing
pzmod validate              # exits non-zero on errors (CI-friendly)
pzmod doctor # one-shot health check (key, config, build, validation)
pzmod backup list

# Add --json to any command for machine-readable output
pzmod mods list --json | jq '.mods'

Run pzmod --help for the full command list.

With --json, any command prints its result as JSON on stdout; errors print as {"error":"..."} to stderr and the exit code is preserved, so scripts can read stdout and gate on the exit code.

Shell completions

pzmod ships completions for bash, zsh, fish, and PowerShell. Print the script for your shell and source it (see pzmod completion <shell> --help for install paths):

# bash (current shell)
source <(pzmod completion bash)

# zsh (add to a dir on $fpath, then restart the shell)
pzmod completion zsh > "${fpath[1]}/_pzmod"

Completions are context-aware: --profile completes your profile names, mods remove/mods show complete installed IDs, and get/set complete the known config keys.

Requirements

• A Steam Web API key (get one here)
• A Project Zomboid server install (or at least a servertest.ini)

Support

pzmod is free and open source. If it saves you time running your server, please consider sponsoring its development on GitHub. It directly funds new features and maintenance. ♥

Upgrading from v2

Config now lives in ~/.config/pzmod (%AppData%\pzmod on Windows). Your existing ~/.pzmod API key is migrated automatically on first run. The old --file flag and the get/set/copy/api-key/update commands still work as before.
