Pontoon - Mozilla’s Localization Platform

Pontoon is a web interface for translating text into other languages. Pontoon specializes in translating websites in-place, but can handle any project that uses one of the file formats it supports:

  • Gettext PO
  • FTL (L20n)
  • Properties
  • DTD
  • INI
  • INC
  • .lang

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
  • Subversion
