Traveller Sector Mapper

Design and explore your own custom sector for the Traveller role-playing game. This tool allows you to generate, visualize, and refine your own slice of the galaxy using authentic, standard Traveller notation and structure.

You can interactively name each randomly generated world, and you can use our AI-assisted naming tool to generate names from a prompt that you supply. See this example.
