Crowdin

Crowdin is a localization platform used by software companies and by many open source and gaming projects. It syncs source strings from code repositories and other systems, shows them to translators in an online editor with screenshots and context, and pushes finished translations back as pull requests or files.

It offers machine translation and AI translation using engines and models you choose, translation memory, glossaries, QA checks and an in-context mode that lets translators edit inside a running web app. An app marketplace adds integrations with content systems, design tools and help desks.

Teams pick it for continuous localization, where translations update with each release, and for community translation, where volunteers or customers translate a product. Before you commit, check the integrations for your code host and content tools, how the project is split into files and branches, and how volunteer and paid translators get permissions.
