Practically every single FOSS application I use is highly useful to me, and of course, free, so I’ll just list them all here.
- Immich - A full-featured replacement for Google Photos, has a sleek UI, face detection, albums, a timeline, etc.
- Paperless-ngx - Document management system, saves me a ton of paper hoarding, and makes everything easily searchable with OCR.
- Syncthing - Simple file synchronization between my devices, on my terms. Doesn’t share data with big tech companies about my files, and hooks up extremely fast P2P connections that beat cloud-based services by a long shot.
- Metube & Seal - Simple interfaces for downloading with yt-dlp, can download from YouTube, but also many other sites. Doesn’t spam you with popup ads or junk redirects like those “youtube downloader” type sites. Seal is my favorite of the two, but is only on Android.
- Image Toolbox - Insanely feature-packed app for doing practically anything you could want to an image. Converting formats, clearing EXIF data, removing backgrounds, feature-packed editing, OCR, convert to SVG, create color palettes, converting PDFs to images, decode and encode Base64 to and from images, extract frames from gifs, encrypt & decrypt files, make zip files, and a lot more. All local.
- Rustdesk - No-nonsense remote desktop, tons of features, simple file transfer, cross-platform compatibility, and P2P communication without needing a third party server if you so choose.
- LibreOffice - Essentially everything you’d get with Office 365 (e.g. Word, Excel, PowerPoint) but without the $150 price point. Compatible with the same file formats, and has the same functionality.
- Cashew - Feature rich financial app for budgeting, tracking purchases, saving for goals, etc. Doesn’t have automatic import, but I find that manually putting every transaction in keeps me aware of my spending much better than before, so for me it’s quite worth it. Install directly from the APK, or use on web though. The version on the app stores has some features locked behind a paywall.
- Linkwarden - Bookmark manager with cross-platform support, a web interface, automatic tagging, automatic archiving of any saved links in multiple formats, collaborative sharing capabilities, and more. It’s free, but you can also pay $3/mo if you want them to host it for you.
Edit: And Umbrel (on Raspberry Pi) if you want to host things more easily. Basically just a much more hands-off, user-friendly docker for people who don’t want to tinker as much.
Edit 2: Non-FOSS, but Obsidian is the best note taking app I’ve ever used. Great selection of community-made plugins (which are FOSS) for additional functionality, and all notes are in standard cross-software-compatible Markdown. No locked-in proprietary formats.
firefox
considering the big monopoly of chrome based is not really free, it’s paid by google or microsoft mining user data
In fairness, Firefox is also paid for by Google.
Firefox gets like 90% of its funding from Google for making Google the default search.
That’s funny, that’s the first thing I change when I set it up on a new device.
Blender, Gimp, Inkscape, OBS (open broadcast software), Linux distros of various sorts, openHAB, LibreOffice, Firefox (and plugins like uBlock), PiHole, VirtualBox, Notepad++, Paint.NET, VLC, 7-Zip, FileZilla…
I’m sure there’s more.
Linux, Firefox, virtualization, Blender, KDE Plasma, ffmpeg, Krita, Inkscape, yt-dlp, Godot, programming language toolchains
add Graphite to the list
woah, ive never heard of this one. it looks awesome. thanks for sharing!!
blender for sure, its amazing, especially when every comparable software is an expensive subscription
Godot
I cant believe it has a better user experience than unity, an app that has a 412 USD/month paid plan
Wikipedia. Not an app but still deserves a mention.
Wikipedia is free because it’s wrong a lot.
People pay for facts, not opinion. When it comes to “news.”
Well… that’s not true exactly…
Besides… innit like 1 guy runnin’ all o’ Wikipedia?
I’d say the same about archive.org too.
VLC is a big one for me.
Wasn’t there some big thing where they tried to buy it and the person that made it was just like “nah”
some new weird video format opens windows stock media player because it’s not yet associated with vlc
“Hey… it looks like your going to have to buy a codec…”
manually open in vlc where it runs seemlessly
People buy codecs?
default behaviour of Windows Media Player…

Oof
Literally never heard of the end user being billed for the codecs.
[Edit]: I think I should rephrase. Could I please be informed about how are codecs priced?
I’ll take “things that haven’t happened to me in years for a dollar Alex”.
A variation happened to me last week that’s why it came to mind. Was opening an mp4 recorded on a digital camera on a new laptop. So the stock player had a go and gave a message similar to the above. vlc was installed moments later and of course had no issue…
It won’t keep track of my place in a Playlist to resume so I trashed it.

I love Aves’ functionalities and speed, but I can’t stand its UI design. Who TF thought it would look good to have a bright and glowing ring around photo folder thumbnails in an otherwise minimalistic UI?
The dev is also a dickhole
I am not surprised but please elaborate.
Can’t believe no one has mentioned Home Assistant. Automation engine for home and have local control over almost everything “smart” at home.
You got a link to that? It has a pretty generic name so I want to make sure I look up the right product. 😅
This one? https://www.home-assistant.io/
Yeah that one
For me: Jellyfin, Audiobookshelf, Keepass, and Aegis
What is aegis in this case? (It’s way too generic to successfully search for)
2FA
The Dialer.
- Comes with every phone
- 10+ digit number instantly connects you with millions of people, services, and institutions
- 3 digits connects you with life-saving emergency support
- Very low-latency voice support
- High quality audio (most of the time)
- No ads
- No obnoxious UI
All kidding aside, I’m routinely astounded at how we have yet to top the ease and utility of old-fashioned phone service.
Until you said kidding I was sold. “Where can I find this elusive beast??”
Wow you’re right. How can we enshittify this? Perhaps you should hear an ad first before we connect you to the other side?
Shit I shouldn’t give them ideas
Plz delete this
7zip
I haven’t used windows in about 15 years on my personal machines but see 7zip referenced everywhere…why is it so popular? Can windows 10/11 or whatever we’re on now not compress/extract most things itself or do people prefer it for some reason (nice interface etc)?
I’m always amazed when I’m following a tutorial written for windows and it says “download and install 7zip, then extract the file using 7zip”. I just right click the file and extract it…
Windows only recently got support for 7z and RAR. For the several decades before that, it supported neither.
Recently? Feels like it’s been more than a decade now…I could be wrong though
You are wrong. Until recently Windows did not natively support 7z or unrar.
Looks like just 2 years ago. My bad!
WinRAR anyone ? 🤭
What do you mean? I paid \s
So it was you

Signal. Highly secure communication. No ads. Easy to use.

Reee
That reminds me, I should donate
