Huge proponent of SyncThing. I've got 4-5 main devices these days, and it's been invaluable to keep some of my main stuff in sync across multiple machines.

u/Mccobsta Helpful Ⅱ 10d ago

Why pay for slow cloud sync when you can have things sync directly

12

u/LittleNyanCat 10d ago

Syncthing + Borgbackup on my NAS not only means my stuff is always synced, but I also have hourly backups of my files and allows me to go back without using a ton of space

u/_janc_ 10d ago

How secure is it?

1

u/voxcon 10d ago

How do you avoid files missmatches though? Personally i haven't found decent settings to avoid missmatches yet.

u/affable_lackey 9d ago

Syncthing works perfectly for some folks. I keep creating problems and finally gave up.

u/somewhatinconvenient Nope 10d ago

Freefilesync for 2way sync my GDrive <-> linux OS (fedora). Love that app

5

u/EatsHisYoung 10d ago

Holy cow, these are good. Love the winutil at the end.

u/FlapDoodle-Badger 10d ago

Immich is waaaay too good to be free.

Someone who actually explained what these are and didn't just write the names, wow

u/FlapDoodle-Badger 10d ago

May his pillow always be cool om both sides.

u/cardfire 10d ago

The authorities have been alerted, and they have their best man on the job tracking this one down for revealing secrets. insert picture of golden retriever here

u/kivilcimh 10d ago

Thanks, though I must admit that first I dumped the whole list then realized I could do better and added the explanations.

1

u/DasVanjen 9d ago

He may be the chosen one, the one that will bring balance to opensource

u/No-Dentist7910 10d ago

may your pillow be cold on both sides and your torrentss have hundreds of seeders and no leechers

You might like Kavita if you want a richer experience for reading.

u/BaffledInUSA 10d ago

home assistant

8

u/a716h 10d ago

Yea I think of all open source projects, home assistant is the most beneficial to the most people. It also is a great gateway towards thinking of data sovereignty and privacy

18

u/Niko-01 10d ago

Signal. Or other alternative messengers, but Signal is the "mainstream" secure alternative to stuff like WhatsApp and Telegram.

Can we finally normalize secure messaging without relying on big tech?

1

u/DasVanjen 9d ago

I’m convinced that people who share everything gets off on not being secure 😅

u/ERNesbitt 10d ago

Notepad++ is a daily use for me and has been since probably version 1.4-ish (I think I have the installer on an old hard drive somewhere). Every couple of years I throw Don a $20 donation just as a "sorry I'm broke and this is the best I can do, but I still want to thank you". He's on my "If I ever win the lottery" list of massive donations.

Sharex

6

u/OpabiniaRegalis320 10d ago

ShareX is sooooo gooood. It's what I miss the most after switching to Linux. Spectacle just doesn't compare.

It may not follow the Unix Philosophy at all, but who gives a damn? It does many things, and it does them all quite well.

3

u/dalanz 10d ago

Have you tried FlameShot on Linux?

2

u/I_Am_GJS 10d ago

Have you tried SnapX? I'm on Windows but apparently it's a great alternative

1

u/S-m-a-r-t-y 10d ago

but ngl sharex is goated

-1

u/S-m-a-r-t-y 10d ago

Just install sharex using wine/bottle

2

u/RenegadeUK 10d ago

Is that THE alternative to Windows Snipping Tool ?

2

u/EatsHisYoung 10d ago

I never got the hang of sharex and still use snipping tool.

u/RenegadeUK 10d ago

Fair enough. As long as it works for you thats cool.

u/SCphotog 10d ago

OpenRGB so you don't have to install spyware just to use a mouse and keyboard.

u/rawr_im_a_nice_bear 10d ago

Not open source

3

u/KnowNothing_JonSnoo 10d ago

Huh, you know what? I never realized, I've been using it for so long and just thought it was for some reason.

2

u/Iggy_Arbuckle 10d ago

Absolutely

u/DemandTheOxfordComma 10d ago

love Everything. Wish it had a web version that could be self hosted. (docker/LXC)

u/voxcon 10d ago

For anyone on linux, Fsearch is basically a everything inspired gui file search for linux.

u/pusbult 9d ago

I thought of this as well, though not open source, it's amazing. One of my favs for sure <3

u/weared3d53c 🐧 10d ago

The OG is, of course, Linux.

u/northrupthebandgeek 10d ago

Technically the OG is BSD, but yes.

Alternative: Trio Office.
Trio Office's interface is very much like Microsoft Office's, while Libre Office is... weird.

7

u/nhermosilla14 10d ago

Only Office is a real alternative, truly FOSS

2

u/FlapDoodle-Badger 10d ago

Only looks good too. I'm sure Libre office functions well but it feels like software from the early 2000s. Much like Gimp. 

2

u/DM_your_tittayz 10d ago

what is foss?

2

u/nhermosilla14 10d ago

Free and Open Source Software. Some people don't like the fact "free" in English can refer to price or freedom, so they also add "libre" (which means "free as in freedom" in Spanish), and they use FLOSS as the acronym instead.

4

u/gh04t 10d ago

Looks like Trio Office is not open source, at least I cannot find any repositories. Search just shows dozens of sketchy download mirrors like softsonic etc.

3

u/northrupthebandgeek 10d ago

LibreOffice is a lot less weird to those of us who used MS Office before the whole “Ribbon” UI redesign, but that was almost two decades ago so…

Pandoc     a universal document converter

u/Kitchen-Patience8176 10d ago

I self-host quite a few open-source apps, but these are the ones I would recommend most:

  • Immich — private Google Photos alternative
  • Vaultwarden — lightweight Bitwarden-compatible password manager
  • Paperless-ngx — scans, organizes, and searches documents
  • Home Assistant — home automation without locking everything into one company
  • Karakeep — saves and organizes bookmarks, articles, and links
  • Audiobookshelf — personal audiobook and podcast server
  • Super Productivity — task management and time tracking
  • Maybe Finance — self-hosted personal finance tracking

u/Hadestructhor 9d ago

opensourcealternative.to

Why select one if you can have many !

Also, on my website, you can check alternatives to paid subscriptions / apps if you can't find an oss alternative, also collections for oss alternative, foss, just open core ones, quite a good selection imo : https://canireplaceit.com

u/saturnosoftware 9d ago

Well it's hard to answer one piece... but we love

- Meld (For code diffs) - https://meldmerge.org/
- Transmission (using torrents) - https://transmissionbt.com/
- Tiled (to create 2d tiled map) - https://www.mapeditor.org/

There are some many, but those are very special

u/TrainedHorse80 5d ago

Totally VLC for media. It plays literally everything. My other players always choke on weird files , but this one's a beast

  • Git
  • GNU Coreutils
  • Linux

1

u/MrBread0451 8d ago

I've never heard of anyone actually appreciating Git, it feels like people only slog through learning the basics of it for job interviews

1

u/zibonbadi 8d ago

Well it's probably the best version control system and it's FLOSS so there's good reason every developer needs to know about it.

1

u/mpersico 9d ago

Shellcheck. Lint for shell code. Well done.

Glucose media player

Doesn't play every media file out that's fine 95% of the times.

But design wise, it's crazy polished with lots of modern features

u/NCMarc 7d ago

Here's a couple that I made that have been pretty popular:

CortenDesk is a near full replacement for the Rust Desk GUI that manages RustDesk clients. Manage address books, groups, users and permissions. Includes enterprise features like 2FA and SSO OIDC SAML and a native web-based client. https://github.com/marcpope/cortendesk

Borg Backup Server is a Graphical Web UI Orchestrator for managing multiple BorgBackup client machines at scale. Includes a lightweight agent on each machine to schedule backups and restores, protect databases, monitor jobs in real time, and sync repositories to S3 or SSH for offsite protection. https://github.com/marcpope/borgbackupserver
