🎯

Built for

It is best for teams managing complex, continuous localization projects for software, websites, or mobile apps that require deep integration with development workflows.

In-Depth Overview

For translation professionals and localization managers, Crowdin removes the friction of manual file handling and inconsistent translations. Its core strength lies in its vast integration ecosystem, boasting over 700 apps that connect directly to your content sources. Whether your team works with GitHub, Figma, WordPress, or Unity, Crowdin automates the flow of source text to translators and back. The platform is AI-powered, allowing you to bring your own LLM keys or use over 40 machine translation engines for a first pass, which can then be post-edited by human translators. This hybrid approach accelerates timelines significantly. Features like built-in QA checks, terminology glossaries, and in-context previews directly within the editor ensure translations are not only fast but also accurate and contextually appropriate. For mobile developers, the Over-the-Air (OTA) updates are a game-changer, allowing instant delivery of new translations to apps without a new App Store release. This combination of automation, quality control, and developer-friendly tools makes it a powerful hub for any serious localization effort.
