We all love open-source software, but there are so many amazing projects out there that often go unnoticed. Let’s change that! Share your favorite open-source software that you think more people should know about. Here’s how you can contribute:
- Single Option Per Comment: Mention one open-source software per comment to be able to easily find the most popular software.
- No Duplicates: Avoid duplicating software that has already been mentioned to ensure a wide variety of options.
- Upvote What You Love: If you see a software that you also appreciate, upvote it to help others discover it more easily.

Let’s create a comprehensive list of open-source software that everyone should know about!
pigallery2 A super lightweight immich alternative which makes browsing photos a breeze
OliveTin, gives you a clean web UI for pre-defined shell scripts, with a dynamically reloadable YAML configuration.
There are a ton of things you could use it for, but I use it for container and system updates. A pre-processor runs on a schedule and collects a list of all containers and systems on my network that have available updates, and generates the OliveTin YAML config with a button for each. Loading up the OliveTin webUI in a browser and clicking the corresponding button installs the update and cycles the container or reboots the host as needed. It makes it trivially easy to see which systems need updating at a glance, and to apply those updates from any machine on my network with a web browser, including my phone or tablet.
Bookwyrm, a book tracker and review sharing plateform that is part of the fediverse allowing you to share your notes and review about books in the threadiverse as well as the twittoverse.
This is not open source software, it’s licenced under the Anti Capitalist Software Licence.
I still appreciate it in this list, but the caveat is important
Newpipe, an YouTube client, which is:
-
ad free
-
lightweight
-
useful, it allows downloading videos, music, and playing them when screen is locked
-
usable without account
-
multi-platform, it can also serve as client for the PeerTube, Bandcamp, SoundCloud
Also shoutout to Tubular which is the same thing, but with SponsorBlock for youtube
I didn’t know it could client for Bandcamp and Soundcloud too! That’s so cool!

Immich is a photo/video hosting solution à la Google photos
Guake, drop down terminal.
I use it for no other reason than it looking cool as fuck.
Portmaster, nowadays mandatory, monitor the traffic of all installed apps and even from the OS itself, blocking with a simple click all unwanted traffic, Inbuild DNS crypt with dynamic filterlists (customizable) blocking ads, trackers and unwanted crap from big companies. Optional SPN service (paid). Windows and Linux.
Hexchat, irc client
The gods of learning and studying with flashcards. You will never want another flashcard program, especially if you were still using Quizlet (so enshittified now…) because Anki uses SRS (spaced repetition system) which makes you review things right before your brain forgets it to reinforce the subject material.
Add-ons: Bread and butter of Anki, I use several to make beautiful automatic flashcards of reading material/videos/games when I study Japanese. There’s an add-on for literally anything.
Cross platform: Free on desktop, cost $25 on iOS, and free on Android, although Ankidroid is an unofficial app. Still great though!
Cloud: Syncs your anki database across devices. If you don’t use anki for a while, will delete from the cloud, but as long as you have your own local database intact, you can reupload again later.
Sharing Decks: If you don’t feel like making your own decks, download ones that others shared for free.
Anki is used by language learners, college students, med students, etc. If you need to memorize it, use Anki.
lol did they really make it paid on ios
It costs money to be an iOS developer
IOS and any apple device is shockingly expensive to develop for.
I recently found out after creating Linux, Linus Torvalds wanted to make a good open source scuba dive log software. Today, it’s probably one of the best, if not the best dive log programs out there and I recently used this myself on a recent dive and it’s great.

Having discarded many other options, I’m looking at Cloud Stack for hosting VMs at home and the job2 site.
This will be like your proxmox, libvirt, openstack (which derived from it), oVirt(RHEV,OLVM,etc).
If you are in the market for a new alternative, please consider this less-known option.
Is this viable for a homelab or is it overkill for that?
agate and amfora, a server and client for the text-based “small web” protocol called Gemini. Allows to publish and read text, images and media in a really simple and accessible way.
(Works also great in a local file network to distribute media and docs).
SMplayer, one of the best multimedia player, fast, capable to stream YouTube and almost everything, all codecs.
Windows (all), Linux, Mac
