The day has arrived. I can finally present you all my new project.
Inspired by NewPipe, Nitter, Invidious or Bibliogram, here comes Lingva, an alternative Front-end for Google Translate.

https://github.com/TheDavidDelta/lingva-translate

It's a completely Free and Open Source project, so you can host your own instance. The directions are on the project's README.
You can also make any kind of contribution. Feel free to Pull Request.
