Tolgee
open sourceApache-2.0Local or hosted4.1kaug 2026In-context translation, screenshots, memory, terminology, review and CI integrations in a much smaller bill.

Mozilla Pontoon
open sourceBSD-3-ClauseSelf-host1.7kaug 2026A mature software-translation system with repository sync, suggestions and review, provided you are willing to operate it properly.

- your data
- Projects sync translations to version-control repositories, while users, suggestions, reviews, translation memory, and job state live in Pontoon's server databases and caches; Mozilla's public instance is not a general hosted service.
