200,000 translations and counting…

When you translate a word in Mattermost to your native language, something special happens. Not only does that language bring with it a unique history and culture, it transforms the experience.

Today, Mattermost is a German experience, it is a Japanese experience, it is a French, Spanish, and Portuguese experience.

In 5 months, we have grown to:

  • 9 languages (with a dozen more in progress)
  • 230 contributors
  • over 200,000 words translated

And we’re just getting started.

Adding more languages to Mattermost with the Mattermost Translation Server

In the past few weeks, we added German, released in 3.2, then Traditional Chinese, Simplified Chinese, Dutch, and Korean, which will be released in 3.3. Many other languages are also making significant progress, including Russian (at 49%), Italian (at 36%), Polish (at 31%), Indonesian (at 28%), and Breton (at 26%).

With native English speakers making up less than 7% of the global population, these translations let Mattermost reach hundreds of millions more people! To give a sense of the community effort, the map below provides areas where at least one major official language has been completed or is in progress.


Although we would like to share a picture of all the 224 people who have joined the Mattermost Translation Server, we’ll share a picture of official reviewers of Beta-quality languages, each whom has been essential in translating their respective language, and maintaining them at high quality.
