Hello i have been working on this Open Source extension (Source code ,available on Github)
I built a free, open source browser extension that adds buttons directly onto Goodreads book pages. Instead of copying titles and searching manually, you just click the badge for whichever source you want.
You can also toggle sources on/off so say if you only want Z-Lib and Anna's Archive badges and not Gutenberg, you can do exactly that.
Supported sources:
Anna's Archive
Z-Library
Project Gutenberg
Planning to add more sources based on feedback.
it is available on :
-chrome
-firefox
Available on Chrome and Firefox. Also for firefox mobile
Anime.js used for animation
