Thanks. I was aware about awesome-selfhosted already.

My idea was something along the lines of:

[…]

Adobe Lightroom -> Darktable, Rawtherappe

Adobe Photoshop -> GIMP, Krita

Autodesk Maya 3D -> Blender

[…]

Additional flairs like “Experimental”, “Professional” would be cool. The goal is to make discoverability quick and easy like in prism-break or OSGameClones. The audience are non-technical users who are just finding out about FOSS.

Edit: I found that AlternativeTo has a license filter and a list of most searched programs in the frontpage. That’s a reasonable option for now.
