The Jetbrains suite of IDE’s. Particularly Jetbrains Rider. The platform ~~they are all ~~ many of them are built on is open source though, and you can get free licenses for all of their products if you are using them to develop open source software!
Steam. The support they have for multiplatform almost feels open source and they have been invaluable for the adoption of desktop Linux
Photoshop is easier to use than gimp. I don’t pay for photoshop, but if I needed something like that I would.
Lightroom. There are lots of alternatives for editing some even FOSS but I haven’t found any usable alternative to the library of Lightroom…
DaVinci Resolve is much better than any open source NLE. Generally, most closed source media production software is better than their open source counterparts except Blender. Blender is incredible and it gives me hope that other open source software can be just as successful in the media industry.
DaVinci is better, but it also provides licence for life. So it’s proprietary but have a good relationship with the customers.
‘Generally’ is a really wide word. Better for what? For who? When? That’s the all question…
Obsidian for note taking, Bitwig studio for audio recording and processing.
Did you check logseq? It’s on flathub
logseq definitely coming along. I tried their donation only sync and it seems to mostly work.
That said nothing has beaten Standardnotes for me. Standardnotes can be found on flathub, fdroid etc. The only drawback is to get the important features you need to either selfhost or buy the plan. The free service is very barebones
