https://alternativeto.net/ is a website people use to list all kinds of alternatives to many different things. Alovoa and Duolicious have profiles on there linking to their websites/repositories/etc. Haven’t checked what license they have but if they have right one they can be forked if needed
Edit: Just found about Fynd too. It’s a non profit but is not open source
