Most used for me is Firefox (in fact I'm so used to it, it didn't even come to mind until I saw so many replies mentioning it!).

The favorite is probably git.

For the recently discovered stuff that would probably be the Astro frontend framework (and Svelte).

Also what a wonderful thread to discover stuff. Thank you all!

BitWarden and Homebridge.

• GNU & Linux (Debian)
• TeX & LaTeX (TeX Live)
• Firefox

Edit (forgot):

• qBitTorrent
• Signal

in terms of time I spend in it:

• linux
• firefox
• vi

In terms of overall usage, gotta go GIMP.

Are we only counting FOSS or would Doom count? If Doom counts, my pick is Doom. Having access to Doom's source code is where I learned a huge majority of my programming knowledge making mods for it.

FFmpeg

Tachiyomi.

Libre Office

Since major projects like Firefox keep getting mentioned, I’ll throw a shout out to Ant Renamer.

It’s simple, it’s FOSS, and it just works. I often - ahem - acquire a number of files from various sources that are labeled like “Mission.Impossible.7.Complete.zHD.2022.xReloadedx”, and an application like Ant Renamer can batch rename files into whatever you need.

For example, if I need to backup or copy a set of game saves in a folder that all need to have the same prefix like N007 from N002, I would have to manually change 10K files from one prefix to the other. Ant Renamer can do everything in a batch that runs quicker than the blink of an eye.

So, Ant Renamer for the win!

I like a bunch of OSS projects but Firefox is way up there above the rest.

Gnome 44, (probably gonna get roasted by Gentoo users) Nano, Librewolf, Free tube, NixOS, Gnu utils, Krita, kdenlive, Gimp Nuclear, Shredder, Gnome disks, Qemu/KVM

Edit- and test disk, it saved my ass this week. I accidentally wrote a new partion table over my hdd that had all my family photos. Used testdisk let it run on my laptop for 22hours recovered all photos and files. Shout out to the Devs for make great FOSS software

• Git
• (Open)SSH.
• OpenStreetMap and Trekarta (Offline OSM maps for Android)

Linux and GNU too :p

• Linux (generally speaking)
• KDE as a whole
• Tusky
• Brave as a browser
• Bitwarden/vaultwarden

Linux, Firefox based browsers, vs code, KDE, and the fediverse.

Firefox and Nethack

Vaultwarden

No love for VLC player?!?

Firefox, probably. Though Heroic Games Launcher is getting there real fast. And currently I very often use Baby Journal, though it's an app I wrote, so I'm not sure I can really call it "favorite", but it's definitely one of my most used FOSS apps currently.

Firefox, VLC, LibreOffice

Os: Linux mint, Solus, endeavour Programs: librewolf, freetube

I don't have "one" favourite but these are up there

firefox and lemmy I guess

Honestly probably neko my friends and I used to love rabbit but it went to shit

I'm only going to mention desktop software, there's too many tools and layers involved in spinning up a server.

Daily use (most used first):

• Firefox
• MRemoteNG
• Notepad++
• VS Code
• Git
• WinSCP
• 7-zip (love the tool but hate the format, storage and bandwidth is cheap now, let's just use zip please)
• VLC
• Python

It's a pretty boring list: connectivity tools, text editors, and version control are placed front and centre. That said they are great tools and I would hate to live in a world where I was limited to only proprietary products

Stuff I wish I had more time to use:

• Godot
• Blender
• Audacity
• Krita

Special mention:

• QGIS (and the whole OSGeo ecosystem)
• qBittorrent
• RetroArch (and all the FOSS emulators it promotes)
• OpenTTD
• GIMP/Inkscape (I don't need them often but I'm glad they are their!)

Going by what I use the most: Firefox, git, less, tailscale, midnight commander

Is Android a valid answer? Maybe not Google's monstrosity but AOSP (although I feel as though it's hard to extricate one from the other save for projects like GrapheneOS).

gnu

Linux, Firefox, PeerTube

If I had to pick only one artifact's worth: bash, probably. Otherwise:

• bash
• vim
• Linux (the kernel itself)
• Kubernetes
• Firefox
• urxvt
• Python
• pacman
• nix
• util-linux
• procps-ng
• iproute2
• iptables(-ng)/ebtables
• GNU parallel
• jq

I got sick of corporations forcing restrictions so looked into alternatives. Learned how to do it myself & haven't looked back:

Joplin notes - use this every day synced to multiple devices Nextcloud - self hosted on a Raspberry Pi 4. Cloud storage plus syncs multiple stuff including Joplin

So many brilliant options on mobile: OsmAnd+ (nav), Antennapod (podcasts), Keepass (password manager), Obtainium (app updater). Was also enjoying Fritter/Quacker (Twitter without needing an account) until Elons recent meltdown. Also enjoying Liftoff lemmy app for Android

EDIT: hot off the press. For those interested, Quacker is back in the game. Not had chance to check Fritter yet

The Linux Kernel and operating system in general. It is simultaneously my favorite and I hate that it killed my prior favorite, the SGI Irix operating system. I was there at the beginning, from kernel 1.1 through today. I remember telling regional directors at silicon graphics that Linux was the future and them disparaging that opinion.

Blender, by far :)

mpv.io !
I discovered it before covid, and it is really lightweight and customizable. So many plug-ins, and they're so simple to create.
I was usually having issues with VLC or settings that he didn't have. No issues with mpv, so far.

Firefox, GNU Linux, VLC, GIMP, Krita, Blender (even if I didn't used it that much), Lemmy of course with it's different FOSS clients

Yggdrasil, an IPv6 end to end encrypted networking proof of concept. There's something about it that I find so innovative that I want it to succeed so badly !
