Pontoon - Mozilla’s Localization Platform

Pontoon is a translation management system used and developed by the Mozilla localization community. It can handle any project that uses one of the supported file formats:

.dtd .ftl (Fluent) .inc .ini .json (WebExtensions)
.lang .po (Gettext) .properties .xliff .xml (Android)

Pontoon can pull strings it needs to translate from an external source, and write them back periodically. Typically these external sources are version control repositories that store the strings for an application. Supported external sources include Git, Mercurial and Subversion.

Deploying

Once you have a running instance, you will likely want to learn about Localizing your projects, and then dive into management tasks.
