Pontoon: Mozilla's localization tool. Translate software with your community and Git.

In simple English

This tool helps you translate your software into many languages. Translators work together on a web page to write new words. Your translated files go straight into your code repository. Mozilla uses it to translate Firefox. You need a server to run it and time to manage users.

What it is

Pontoon is a web-based translation management system built with Python and Django (a framework, which is a set of pre-written code blocks that helps build web apps faster). It syncs directly with Git repositories to keep your translation files up to date.

What it is good for

Solo builders who manage open-source projects or apps with global users and want volunteers to translate their interface without touching code.
