About PetitMaker

PetitMaker is an unofficial map-planning tool made by players for Petit Planet. Arrange terrain, water, roads, objects and annotations in your browser, explore your ideas, then build them in the game.

The editor checks the building rules it implements to help identify layout problems. Game versions and actual building conditions may differ from the editor; use the game itself as the final reference.

Player volunteers maintain the project in their spare time. The roster below is ordered by romanized name; each link opens the member's Bilibili profile.
