Crowdin

Crowdin is a leading cloud-based localization and translation management platform used by over 2 million users to translate software, apps, websites, games, and digital content into multiple languages. The platform bridges the gap between development teams and translators by integrating directly into existing development workflows through 600+ integrations with tools like GitHub, GitLab, Bitbucket, Figma, Sketch, WordPress, and more. Crowdin automatically detects new or changed content in source repositories, sends it for translation, and syncs completed translations back — eliminating manual file handling entirely.

What sets Crowdin apart is its combination of AI-powered translation, collaborative editing tools, and developer-friendly architecture. Crowdin AI assists with machine translation, content generation, and quality assurance across all plans. The platform supports unlimited translators on every plan with no per-seat fees for contributors, making it uniquely scalable for open-source projects and large localization teams. Translation Memory and Glossary features ensure consistency across projects, while the visual In-Context editor lets translators see exactly where their translations will appear in the live product.
