How do we translate our web pages and applications?


I speak natively Russian and Maxence speaks French, so if we need these languages to be on our application, we do the translation by ourselves. To do the English translation, we use DeepL. As our level of English is quite good, we are able to check the machine translation, sometimes using the context dictionary - Reverso Context. If we don't need to translate our application immediately and it can wait, we ask our users for help and manage it in POEditor. If a translation is necessary, we pay people on Fiverr. When have more money, we will certainly use OneSky.


That's it. In this article, I covered 5 completely different ways to translate your application. Depending on your needs and resources, you can choose the one that suits you best or combine all of them, like we do.
