GNOME Web aka Epiphany comes to mind first.

Funnily enough, in my native languages, first version reads more natural, since that’s how you write stuff :D

From quick test, LibreTranslate UI can’t work without JavaScript… Hm, then maybe you can look for Mozhi? https://codeberg.org/aryak/mozhi I tested one instance that I found, https://mozhi.adminforge.de/, with disabled JavaScript via Ublock, and seems it worked!

Might not be something that you exactly need, but might help you:

• https://github.com/DavidVentura/offline-translator if you are on Android, it is fully offline, once you download an translation models. Also it provides option to turn on LibreTranslate-compatible server, so other programs that supports this API can call this servee.
• https://github.com/you-apps/TranslateYou — Multi-service client, can translate from many different service, including ability to provide your own addresses to other (or your own) instances.
• You can selfhost earlier mentioned libretranslate https://libretranslate.com/, it is relatively easy to do. Translation quality quite good, but it’s model are somewhat really bad with single word translations. If you want to translate mostly single words, then some dictionary solution should be preferred.
• If you are on Linux, you can check out https://flathub.org/de/apps/net.mkiol.SpeechNote — it’s primary function is to deal with text-to-speech and vise versa, but it also provides translator. Translation models here are based on Mozilla models that you might had used in Firefox.
• Also Linux app: https://flathub.org/de/apps/dev.ters.LocalTranslate, it also uses Mozilla models under the hood.
