If you’re building a multi-language website or app, you probably use language files. When you change content in one language file, you need to remember to update the other language files. Even with source control, this can get messy pretty quickly if you have many languages, many translators or a large site.

String was built to keep things organized. It can manage your language files – from PHP to PO to Rails to iPhone apps. Import and export easily. You can now easily add languages and sections to your site. You can also invite users and control permissions. String is free, with no project limits. Invite as many users as you like. You’re free to extract all your data and close your project at any time.
