Do you struggle to localize your Ruby on Rails apps?

LocaleData is a simple translation management platform, which can help you collaboratively work on your YAML translation files even with your non-technical teammates.

How does it work?

1. Import

Start by uploading all your existing project translations in YAML file format.

2. Translate

Invite teammates and translators to collaboratively work on your project translations.

3. Export

Download your finished translations in YAML file format (and go to step 2).

Why to choose LocaleData?

No more syntax errors

Use our simple translation editor with many predefined languages to manage your locales.

YAML import/export

LocaleData provides you easy import/export functions for your YAML i18n resource files.

Easy collaboration

Each project can have multiple collaborators with different user roles and access permissions.

Private projects

All LocaleData projects are private. You determine who can see and edit your translations.


In LocaleData we are passionate about minimalism and simplicity in user interface design.

It's FREE, but if you can donate, please do.

LocaleData is still in the beta version. We've decided not to provide any paid subscription for now, so you can sign up and use it for free without any restrictions. And if we get enough donations, it can stay free forever.

Developing and maintaining this project takes a considerable amount of our spare time. In addition, we have other expenses associated with it (running a server, sending emails, ...). If you like it and/or if it has helped you in your work or personal projects, it would make sense to sponsor us. It ensures the LocaleData stays healthy and actively maintained.
