Keep all translations in one place while connecting your teams via Crowdin

Connect with your content, marketing, and translation teams in one collaborative space:

  • Screenshots for additional context.
  • Highlight HTML, placeholders, plurals, and more.
  • Describe the context and set character limits to ensure the translation fits the UI.
  • All translations are done online or can be uploaded to the platform.
  • Jira integration to notify you about source string issues.
  • Tips for translators to ensure there is no extra space or broken code.

Ship faster with localization running in parallel

Keep developing new features and improvements while translators receive new texts in real-time. Release multilingual versions for customers around the globe simultaneously.

Release your product in several languages at once

Help users from different regions use the latest version of your product in their language:

  • Get feature branches translated independently from the master branch.
  • Translators work together in one place to boost productivity.
  • Never deal with translations in spreadsheets or email attachments.
  • Source texts are updated for translators automatically and in real-time.
  • Automatically pull completed translations that are ready to be merged.

Seamlessly integrate localization during any phase of your development cycle

Automate the integration of source texts and translations between Crowdin and your source code with one-click integration or customizable solutions.

Define your translation strategy

Decide who will translate your content:

  • Invite your team of translators (in-house translators, freelancers, or translation agencies you already work with).
  • Order professional translations from a vendor (translation agency) from Crowdin Vendors Marketplace.
  • Configure machine translation engines.
  • Engage your community.

VCS: GitHub, GitLab, Bitbucket

Source strings are pulled automatically and are always up to date for your translators. Translated content is automatically pushed to your repository as a request.

Automatically pull source strings to Crowdin and push translated content to your repository
