If you never heard about alternativeto before, it’s essentially a website listing alternatives to popular softwares. This website seems to be quite well known in privacy-concerned community and a lot of open source software are listed on it.
When receiving the email from alternativeto confirming SimpleLogin is approved, I’m quite happy even this is a “tiny” accomplishment. Posting on this website is actually an advice from a user who happens to be a veteran in privacy-concerned community and who likes SimpleLogin a lot. As I’m pretty new to this community, advices like this are more than welcoming!
