It's intended to be used for role-playing games such as D&D and other tabletop games, useful both before a session as a mapper and during a session as a virtual tabletop. All maps are stored indefinitely in the cloud.

Mipui is free and open-source, and requires no installation or registration. It's powered by HTML5 and Javascript and so would work on any newer browser without requiring any extension or plugin.

It can also be used as a virtual tabletop (VTT), since edits are live and it supports fog-of-war (with a line-of-sight reveal tool) and other VTT-friendly features.
