1. About This Page
ZakGT (website, backend server, desktop Hostapp, and mobile app) is built on top of a number of open-source software packages. This page lists the major third-party dependencies bundled into each surface and their licenses, as required by their respective open-source terms. Version numbers change frequently as dependencies are updated; the license grant for each project does not change between routine version bumps. For the authoritative, exact list at any point in time see package.json (website) or requirements.txt (server / Hostapp) in the ZakGT source tree.
