Tolgee: Pricing, Features & Alternatives

Tolgee's differentiator is the SDK: run your app in development, alt-click any string, and edit the translation in place with the surrounding UI as context — the thing spreadsheets and ticket queues never give translators. It handles machine translation, glossaries and AI translation with brand context, and the whole platform is open source if you would rather host it.
