Offline translation interface for online translation tools.
Offlate is a graphical interface designed for translators of free and open source software. Software projects in the free software community use a wide range of online platforms (or no platform at all) to manage their translations. Offlate is able to connect to many different platforms, copy the translations locally, and let you work on them on your computer, offline and in a unified interface.
