localizr.net is a place where software translators can participate in creating software localizations for different languages. The service supports the translation process by offering a special editor which can be used to build and edit a localized software version.
Site visitors can browse and search for available localizations and download them to use with the software.
Software developers can contribute to the service by registering special developer accounts and submitting their multilanguage-supported software. With every new release they can update the base language file to make it available for the translators.
