The ASF Translation Service provides the Pootle localization tool to help projects that want to provide documentation and user-interface text in multiple languages. NOTE: While several ASF projects continue to use Pootle, AFS is not approving new Pootle use.
Apache Tomcat uses POEditor to localize its log messages and other text. POEditor provides free, unlimited licenses to open-source projects. PMC member Mark Thomas provided a description of the Tomcat localization process.
