OBS
@dl007 kde and vlc
Firefox, Blender, OBS, FreeType…
Honestly, Lively Wallpaper. You can set anything as your wallpaper and it'll work wonderfully: a video streaming directly from YouTube, a Unity game, a shader, a browser tab, a gif... You name it!
And the API supports sound input so anyone can make their sound visualizers now. I always wanted to do that as a kid after being an og WMP fanboy and finally got that knocked off my bucket list
Omnivore! It's just a "read it later" app, but so nice to use. I enjoy newsletters again, because they all go there instead of in my emails, and they all have a uniform look to them now. Sorting by labels and syncing highlights to my Obsidian inbox page are great features. And they said bulk editing is coming soon.
Also bitwarden, lichess, and qbitorrent.
Blender is the first one that comes to mind
I abide by the side of the fence that something performing well means it probably is open source, rather than not.
An open source project's only reason for existing is to work and do its job.
Most paid apps trade userfriendlyness for less features, and making a dollar is sometimes more important than making sure it went to good use.
Because it hasn't been mentioned yet, I add DigiKam. That and darktable are a fantastic team.
Can't honestly say "I can't believe..." for a long time now, because I actively select for openess. To be fair, I am old and started playing with Free software in the '90s, switched over to Linux desktop fully as student in 2003, etc.
You will get already many responses to your question. Let me answer you the opposite.
I concluded after starting using FOSS software, that it was much easier to find high quality programs searching by "open source [feature I want]" or "[program] alternative open source" and I have lost hours and hours searching, installing and cleaning my PC because of malware I downloaded.
Kicad.
Cura. I've been using it for over a decade, and it is still hands down the best 3D printing slicer. S3D (I think that was it's name) was on top for a while, but was ~$200 for features that really weren't worth the money.
@dl007 Marlin, RepRap, PrusaSlicer: a vast part of the 3D print ecosystem has seen a huge leap given all the open source projects it is quite impressive to compare the current state vs where it was a few years ago
Not sure if these have been mentioned already but gstreamer and llvm.
Joplin for notes, Inkscape, and Darktable.
One I never see mentioned is Azuracast, which lets you run an entire radio station. Cool stuff.
Mixxx is the first that comes to mind
Neural amp modeler

For me it is KDE Plasma desktop. By far the most powerful, customizable, flexible and innovative of the computer desktops today. And despite all these features and power it is still one of the more lightweight ones.
Also there are other great KDE apps and GNU/Linux operating system in general. Just love how they respect my digital rights and freedoms and my privacy and I do not need to use proprietary alternatives which are just getting more bloated and include more and more spyware. Not to mention their constant dumbing down of the interface and closing it up.
- Ice Cubes
- LanguageTool
- Telegram client
- Xonotic
- SearXNG
There are many great open source projects that are amazing but the model is to avoid developing critical core functions and put them as a separate paid system. Abusive imo
FOG Project - it has saved me a ton of time at work deploying labs and software and I believe it only has a couple developers.
It’s probably safe to use but ghidra feels so sus considering who made it
For some reason i thought Brave was closed source
