LibreOffice, I'm not sure it's better than M$Office per se, but it does everything most people need it to.

Chocolatey GUI > Microsoft store

Inkscape, I'm not even sure what the proprietary version is?

I run Plex and jellyfin side by side. Plex usually gives me the most hassle free experience so I use that most of the time.

I prefer the flexibility of creating user accounts myself on jellyfin so that's nice.

But jellyfin after being up for 4~5 days balloons to 6GB of RAM consumption while Plex stays at ~200mb. Really annoying.

(neo)vim

Linux in general. MacOS if fine, but the app ecosystem is often annoying. And Windows is just a complete dumpster fire these days.

I was setting up a Plex server, but when I noticed I had to pay to be able to play my own content on my phone I immediately switched to jellyfin. Haven't been able to test it yet, but as long as I don't need to pay them to be able to watch my own content on my own devices on my own network, I'll be happy!

I switched to Jellyfin two years ago and never looked back.

I could be biased but 2009scape. While originally a Runescape clone of 2009, they've preserved the integrity of the game much better than the official versions

1. XBMC forked off into Plex. Plex introduced a far better UI.
2. XBMC became Kodi. Kodi learned from Plex.
3. Jellyfin came along and learned from both of them.

So I don't think you can really criticise Plex too much here. They were perhaps getting complacent and they've definitely been shown up, but they were an important step to where we are now.

On Android; mpv, KeePassDX, FlorisBoard, AntennaPod, Read You, NewPipe, Jerboa, Unitto Calculator, CloudStream, Aegis, TrailSense, OpenKeychain, K-9 Mail, EDS lite, ViMusic, InnerTune, GrapheneOS Camera, Librera FD ...are my favourites.

Kicad beat the crap out of EagleCAD. So much so that autocad just folded and discontinued EagleCAD.

Pandoc. I'm not even sure there is a decent alternative.

I would love to use Jellyfin but it (indexing, changing metadata...) is too slow with a few hundred movies and shows on my Synology. Plex is way faster.

The scanner app on Linux is far better than Windows: auto preview white scanning, auto pdf creation WITH multiple pages.

Godbolt. Thank whatever cosmic great fortune sent goldbolt.

The fact that no one in these comments, seems to have had a really decent FOSS IDE \ engine to recommend for 3D game development, makes me sad.

Like, Unreal is pretty great, but it's not FOSS (& won't run on any of my machines anyway).

Is there anything FOSS that really streamlines 3D game development?
(I want to say Vulkan but I feel like that's some sort of perennial "gotcha!" joke, at this point?)

Pidgin. Consume soo little memory in comparison to other chat applications. Is really fast, just try start and scroll history in a chat conversation. But it looks ugly.
