Transifex (previously known as Indifex) is a globalization management system (GMS), a proprietary software, and a web-based translation platform.

It targets technical projects with frequently updated content, such as software, documentation, and websites, and encourages the automation of the localization workflow by integrating with common developer tools.

Transifex is written using Django and Python by founder Dimitris Glezos under a Google Summer of Code project.

As of March 2014, transifex.com has over 17,000 project translations hosted across 150 languages, including Creative Commons, Coursera,[7] Django and Django-cms,[8] Dolibarr, Eventbrite, Mercurial, Bitbucket, GlobaLeaks, TalentLMS,[9] MeeGo, OpenStack,[10] Pinterest,[11] qBittorrent, Reddit,[12] Xfce,[13] Wheelmap.org,[14] VLC,[15] and others.

Once the content is translated, the project owner can download it manually or pull it using the Transifex command-line tool.
