So someone already mentioned this, but there is this list I maintain on Codeberg: https://codeberg.org/RayJW/awesome-foss

There is also this website which is pretty neat if you’re searching for an alternative for a specific software: https://www.opensourcealternative.to/

This is my list, maybe it will be useful. :)

github.com/Psyhackological/AAA

codeberg.org/Psyhackological/AAA

https://codeberg.org/RayJW/awesome-foss

Watch out for “awesome” lists.

Can you be more specific. Alternatives for what? One time list or would you want and expect it to be constantly updated? By whom?

This list and many others like it, may be what you’re looking for.
