Weblate
Weblate is an open-source web-based translation management system that provides a collaborative platform for teams to review, suggest, and approve translations in real time. It functions as a continuous localization platform, automatically synchronizing translations with source code changes in version control repositories, and can be deployed either as a self-hosted server or through a managed cloud hosting service.
The system integrates directly with Git hosting platforms like GitHub, GitLab, and Bitbucket, storing all translations in version control with individual translator attribution recorded in commit history. It includes customizable automated quality checks to catch errors and maintain consistency across translated strings, along with terminology management through shared glossaries. The platform supports over 500 languages out of the box and provides a web-based translation editor with peer review tools, keyboard shortcuts, and visual context such as screenshots and descriptions to aid translators.
Weblate offers flexible deployment options including Docker, Kubernetes, and OpenShift containers, as well as cloud appliance images for private infrastructure. It provides a REST API for programmatic integration, a command-line client for remote automation, and an add-on plugin architecture for extending the localization workflow. The system includes role-based access control, machine translation integration, translation memory reuse, and background task processing via Celery workers for automated synchronization and scheduled maintenance.
