I want you all to hear about this actually good website: alternativeto.net

Type in the software that you want to replace.

Then toggle filters for your OS and if you want Properitery (paid or freemium) or FOSS.

Whole thing is based on community votings.

You can also vote down and describe with text a feedback, why a listed software doesnt really make a alternative to your software.

Or why it is a good alternative.

Sorry for bad formatting. I am writing this on mobile.
