You may want to add a custom language that is derived from an existing language. It’s useful if you want to adapt some translations to another instance of your application, or to a specific customer.

The structure of a custom language is: existing language code + - + custom text, where custom text can only contain alphanumeric characters and -.

Examples: en-microsoft or fr-BE-custom.


Custom languages can be added like any other language.

Fallbacks work as expected. It means that if the en-microsoft.some_key is missing, then it will fallback to en.some_key. So you only need to translate keys that should be customized.

Note that fallbacks are chained, so en-US-custom will fallback to en-US that will itself fallback to en.

Just make sure to add config.i18n.fallbacks = true to your config/application.rb file. You can find more information about this here.

Using GetText syntax, it will only fallback to the source language. So either you create a fallback mechanism by yourself or you avoid fallbacking by translating everything in for that custom language.

We are proud to announce that is now supporting Laravel the same way as Ruby on Rails.

Laravel Translation Made Simple

Syntax is a bit different but it works exactly the same:

  • t('source text') for GetText
  • trans('some.keys') for PHP key-value

Just select your favorite framework when creating a new project and you will receive the installation instructions:

If you like working with us and you know some fellow Laravel developers, please tell them we’re open for business. For each positive or negative feedback, we’ll offer them 3 free months on

We’d like to thank @armandsar for helping us bootstrapping this package.

You will find more information about the installation and usage of the Laravel package on the official repository:

A year ago we added a history feature to It allows you to view the history of all your translation projects.

Better History

We have been working on the improvement of that history lately. It was not possible to filter it by language, user or change type, and we thought it was a missing option.

You can now open the history modal from any of your projects:

Translation History Modal

The history contains all types of changes:

  • translation of a segment;
  • source text editions;
  • comments and tag additions/removals;

and you can filter on them.

Email Digests

As the project owner, being notified when a translator makes some change on the project is a must-have. Also, if you are the responsible translator for a specific language, you want to know when new non-translated segments are added to the project.

That’s why we have added email digests for activity on your projects.

All changes performed by others on your projects will be compiled into a nice email. Don’t worry we won’t spam you too much!

Translation History Digest

You are watching all of your projects by default. You can unwatch activity on a per-project basis directly on their respective translation pages:

Translation History Notification Watch

We hope you will enjoy the new history and we are as always eager for feedback!

Maybe you’ve noticed that the URL of the page changes almost everytime you do an action on the translation interface: moving from a segment to another, changing filters, searching a word, etc.

Smart URLs

Actually the current state is kept in the URL so you can share URLs from your work with your collaborators/translators. If they follow the link, they will get right where you were: same filters, same selected segment, same target language.

Also, the navigation history is preserved so the back button of the browser will bring you back exactly where you were before. It’s not much, but that’s unfortunately not always like that on modern one-page applications.

Sometimes you have long texts to translate. Two, three paragraphs or so. Working on such texts in a small textarea might be quite frustrating for the translator.

For that reason we recently added a fullscreen mode that you can toggle with the ESC key.

Fullscreen translation

This mode also has the advantage to let the translator focus on his work and not be distracted by the other features of the translation interface.

Of course in this mode you can still navigate through the segments using the arrows or the usual keyboard shorcuts.

Let’s hope this new mode will enhance your translation workflow!
