About PZ Base Planner

PZ Base Planner is a free, browser-based tool for sketching Project Zomboid safehouses before you commit a single nail in-game. You lay out walls, doors, gates, fences, windows, generators, containers, and other build elements on a multi-floor grid, choose the material tier for each piece, and watch a threat overlay flag the walls most exposed to zombie attack paths so you know what to harden first.

It exists because Project Zomboid's build system punishes mistakes. Once a metal sheet wall is up, undoing it means a slow, noisy dismantle that can cost you half a day and draw a horde. Planning the layout first lets you commit to one defensible base instead of half-building three and dying at sundown. The planner has a narrow job: pick materials, place them across floors, see where the threats actually come from, and share the blueprint as a permanent URL or a PNG so your group can iterate together.

It's built for solo survivalists planning a long-haul fortress, co-op groups dividing up wall duty, and anyone who has lost a run-of-the-mill bungalow to a window they forgot to barricade. Everything runs entirely in your browser — there are no accounts, no installs, and no save-file syncing. Your blueprint is encoded into the page URL, so bookmarking it (or sending the link) saves the layout for good. We support vanilla Build 41 and Build 42 elements; heavy structural mods aren't in the picker yet.

PZ Base Planner is made by Valin Studio, a small independent studio building practical, no-nonsense web tools for the games we actually play. It's an unofficial fan project and is not affiliated with The Indie Stone. If it saves you a base, that's the whole point.
