What is Crowdin?

Crowdin is a localisation management platform: a cloud workspace where product strings, documents, websites and subtitles are collected, translated and delivered back to the codebase. It keeps a translation memory and glossary so repeated wording stays consistent, and it mixes machine translation with human review from your own translators, an agency or a community. Integrations cover GitHub, GitLab, Bitbucket, Jira and Figma, and the CLI and API let translation run inside a build. The AI additions are practical rather than headline: machine translation suggestions, quality estimation and automated checks for broken placeholders or markup.

FAQ

Is Crowdin a translator or a management tool?

Both, in a specific sense. It manages the workflow - who translates what, into which language, using which memory - and provides machine translation plus editing tools inside that workflow rather than acting as a standalone translation box.

How do finished translations get back into the code?

Through integrations and the CLI. A commit can trigger a string sync, and translated files can be pulled back into the repository or build pipeline automatically once a language passes review.

When does the free tier stop being enough?

When you outgrow its project and word allowances, or need private vendor workflows and advanced quality controls. Small open-source and single-product projects often stay inside it for years.
