Luke (SEVNC3) made PZMM because setting up Project Viewpoint by hand was a pain. Then it kept growing: it's a proper mod manager now, it gets you into modded servers with the right mods, and it runs dedicated servers too.

Sort your mods, or let Autosort do it

Drag mods into groups and star the ones you care about. Autosort puts frameworks first and translations last, and keeps every require, loadModAfter and loadModBefore. Ctrl+Z if you don't like it.

Every Workshop map on one grid

See which maps clash before you subscribe. It picks the biggest set that fits and writes the map order.

Project Viewpoint and ZombieBuddy, set up for you

One click downloads Viewpoint and ZombieBuddy, sets ZombieBuddy up and makes a separate Viewpoint profile. When a game update breaks it, Repair fixes it. Viewpoint is by ellu and norkus, ZombieBuddy by zed-0xff; PZMM just installs them.

Also

• Join a modded server: it downloads exactly the mods the server runs, in a profile of its own
• The whole Workshop in the app: search, install, and required mods come along. No Steam login
• Keep your mods up to date: read each update's change notes before you load a save
• Build 42 wiped your mod list? It puts it back
• Find the broken mod halves your list until the crash goes away
• Profiles, save backups, 10 languages

New server… installs a dedicated server with SteamCMD, with mods from a profile or a collection. Then you get a live console that points errors at the mod that caused them, restarts that warn players when a mod updates, backups, and Discord alerts, bot commands and a chat relay. It also adopts servers you already have, and talks RCON and FTP.

• Windows: grab PZMM_<version>_x64-setup.exe from the latest release. If SmartScreen moans, click More info, then Run anyway (it isn't code-signed yet).
• Linux: the .AppImage (any distro) or the .deb (Debian/Ubuntu). SteamCMD needs lib32gcc-s1.
• No desktop? pzmm-linux-x64 and pzmm-windows-x64.exe are the command-line version.

It finds your game itself, turns your current mods into a profile called Default, and updates itself with signed updates. It only ever deletes mods it installed, and it shows you every change before joining a server or setting up ZombieBuddy.

Warning

Early access, so back up your saves. Only download it from GitHub Releases. Bugs go on Discord or in an issue, with Settings > About > Copy diagnostics pasted in.

PZMM was created by Luke (SEVNC3), who has stepped away from modding, and is now maintained by byDGV.

For developers: command line, building, releasing

Command line (pzmm)

The command line and the app share the same profiles and data, so a headless server box can run the same setup. Add --json to the read commands for machine-readable output.

PZMM_DATA	%LOCALAPPDATA%\pzmm or ~/.local/share/pzmm	Profiles, backups, SteamCMD
PZ_GAME_DIR	found in your Steam libraries	The game's install folder (used for ZombieBuddy)
PZ_SERVER_DIR	found in your Steam libraries	The Dedicated Server tool's folder
GITHUB_TOKEN	none	Private repos or a higher GitHub API rate limit

Build from source

This needs Rust and Node.js 22.18 or newer (the self-checks run TypeScript directly). On Linux it also needs the Tauri system packages.

cargo test                                  # core + CLI
cd app && npm ci && npx tauri dev           # desktop app, live reload
cd app && npx tauri build                   # installers in target/release/bundle

Path	What it is
crates/core	Shared logic. Everything specific to Project Zomboid lives in src/pz/; downloads (Workshop, GitHub, local) in src/sources/.
crates/cli	The pzmm command line
app/	The desktop app: Tauri 2 with Svelte 5

The full plan is in docs/FOUNDATION.md. To release, set the new version in Cargo.toml (and app/package.json), then push a matching v* tag. CI builds every download, signs the installers with the updater key (GitHub secret TAURI_SIGNING_PRIVATE_KEY; a copy is in the maintainer's 1Password), and publishes latest.json, which installed copies check for updates. The release page starts with docs/release-notes/install.md, then the bug-report note (docs/release-notes/bug-report.md), then docs/release-notes/<tag>.md.
