Habitat is a free open-source, self hosted social platform for local communities. It is aimed at fostering local community discussions and discovery of areas of interest. This is why it is built primarily around location. A Habitat instance centers on a specific area, and the local community can make generic posts about that area, or they can make posts about specific locations in that area.
