Weblate is an open-source continuous localisation platform that connects teams to their code repository. It provides translator context, shared terminology, quality checks and space to discuss wording and review work. AI and machine translation are optional; you decide when people edit, accept and approve, and which external translation services, if any, are used. Weblate can be self-hosted, for example with Docker, Kubernetes or a virtualenv, or used as a managed service.
Weblate is licensed under the GNU GPLv3+. The provider is Weblate s.r.o., with its registered office in Cvikov, Czechia, so in the EU. According to the documentation, data of Hosted Weblate and Weblate Cloud is stored and processed within the EU, with primary locations in Germany at Hetzner. When self-hosting, you decide where it runs and who has access. This makes Weblate suitable for organisations that want to keep their translation data under their own control.
