Weblate Translation Platform

This web-based continuous localization platform integrates tightly with version control systems, enabling collaborative translation of software, documentation, and web content by communities and professional translation teams. Created by Michal Cihar in 2012, the platform has over 4,500 stars as of 2026 and is used by major open-source projects including Fedora, LibreOffice, OpenSUSE, and the Tor Project. Key features include: Git and version control integration (automatic syncing with repositories, committing translations back, supporting Git, Mercurial, Subversion, and GitHub, GitLab, and Gitea pull requests), translation formats (over 40 formats including GNU gettext PO, Android strings, iOS strings, JSON, YAML, XLIFF, CSV, and PHP arrays), translation memory (shared memory across projects with TMX export, suggesting previous translations for recurring strings), machine translation (integration with DeepL, Google Translate, Microsoft Translator, Amazon Translate, LibreTranslate, and OpenAI for AI-assisted suggestions), glossary management (project-level terminology management with consistent translation enforcement), quality checks (over 40 automated checks including placeholder mismatches, format string consistency, plural form validation, and markup consistency), screenshot context (uploading screenshots and linking source strings to UI elements), contributor management (per-project access with role-based permissions including translators, reviewers, and managers), review workflow (two-step review with suggestion, review, and acceptance stages), add-ons (automated string cleanup, MO file compilation, component discovery, and bulk editing), activity tracking (daily, weekly, and per-user statistics), and RESTful API for CI/CD integration.
