OpenStreetmap as an alternative to the closed source maps.

OrganicMaps or OsmAnd to navigate and StreetComplete or EveryDoor to improve it.

LocalSend, a cross platform alternative to airdrop and nearby share.

My family uses it for almost all of our filesharing. IPhone to android, iPhone to windows PC, android to macbook, etc. Its works really, really well.

Syncthing, a peer to peer file synchronize that basically everyone needs, they just don't know it.

Bitwarden an open source, simple password manager it does it's job very well

TrailSense, an easy to use, comprehensive wilderness tool.

The goals of the developer are fun to consider:

Goals

• Trail Sense must not use the Internet in any way, as I want the entire app usable when there is no Internet connection

• Features must provide some benefits to people using the app while hiking, in a survival situation, etc.

• Features should make use of the sensors on a phone rather than relying on stored information such as guides

• Features must be based on peer-reviewed science or be verified against real world data

Likewise, the features being developed under those goals are great for getting outside:

Features

• Designed for hiking, backpacking, camping, and geocaching
• Place beacons and navigate to them
• Follow paths
• Retrace your steps with backtrack
• Use a photo as a map
• Plan what to pack
• Be alerted before the sun sets
• Predict the weather
• Use your phone for astronomy
• And more

Ruffle: You may not know it but most old Flash games (and basically every anmiation) can be played again with this, modern and in a Browser sandbox. Website owners can include it in the backend with a few lines of code and all flash games work again automatically, and it's also available as desktop app :D

Keepass/KeepssXC/KeepassDX (password manager for desktop)

Syncthing to synchronize database between devices.

Jitsi - Open-source and self-hosted video conference platform. You can even try it directly on their website.

IPFS - A distributed file sharing technology which is wonderful for file or site hosting (edit: wether it is uncensorable is open for debate)

Rust - A programming language and a powerful compiler that creates compiled memory-safe programs and can be used nearly everywhere

Fedora + KDE - A combination of a stable modern OS and a complete desktop environment

Wine - launch Windows programs on the latter

Lemmy

Bonus : AlternativeTo to find good open-source alternative software

PostmarketOS to actually own your phone.

VSCodium is the open source part of VSCode, so I prefer to use that.

Mull is firefox on android without the proprietary parts. Heliboard is a good android keyboard.

Paperless-ngx that allows you to self host an easily browseable archive of your documents. Fully featured with OCR, ML-powered categorization and the works.

https://docs.paperless-ngx.com/

GrapheneOS!

KDEConnect - I use it on Windows and android phone. Very nice when you get security codes or links on phone, want to send files or when I want to control audio|video and I watch from the couch.

in general: Fdroid nearly always has a more feature rich and performant alternative

Darktable Great digital photography RAW editor. Alternative to Adobe Lightroom.

Xournal - a great way to draw on pdfs

btop is a TUI (or TTY) resource monitor and management tool

• Very intuitive and easy to use
• Highly configurable
• Supports mouse
• Option to filter processes
• Theming support

linux, unironically. literally all local infrastructure is running on windows, despite the security risks this entails.

KepassXC for PC and KeepassDX for Android phones.

I personally would recommend it over Bitwarden since with Bitwarden you NEED internet to access your passwords, and even if is open source, i canmot trust it, security breaches can happen in any time, having your vault locally stored helps a lot.

There are more but i can't Remember them right now.

Video Downloader. https://github.com/Unrud/video-downloader

Strips all junk off any video url so you have the mp4 or mkv.

Use this to add youtube videos/playlists to jellyfin. Doesn't have to be youtube. Downloads any videos from a link.

Can also save audio only from video links if you want to.

Seal (Android)

It's an audio/video downloader that uses yt-dlp internally.

It's not only useful for YouTube, it can download media from most sources.

It also has a little "quick download" share target that comes handy when browsing YouTube (Music) and Po...other sites with tons of media 👀

Shotcut an amazing video editor.

Openwrt Routers can be fun too!

DietPi, for setting up an SBC (ie raspberry pi) with common server software. very good for a first-time self hoster like myself.

Universal UnifiedPush support so we can manage our own push notifications through something like NextPush on your Nextcloud. At that point I could completely remove Google Play Services from my phone without much trouble.

Owncast Stream whatever you want on your own platform and announce natively to the Fediverse!

IDK why but tons of folks think it's not feasible as they need million dollar computers. I've streamed to 70+ open streams, albeit as a test, on a like $5/month VPS. The key is that the resources needed are how many qualities you're transcoding, not how many folks are viewing. Yes bandwidth is needed for each viewer, but that's significantly less than people imagine.

Full transparency I run the [email protected] community, but I'm in no way affiliated with the project. I just love open platforms and open source.

Kanipaan https://yu7.in/kani, a CLI calculator.

For 3D Modelling / Printing, if you have even a little bit of programming / scripting ability, OpenSCAD is amazing.

It's basically just a small scripting language for generating 3D objects and performing 3D modelling operations and its so handy to be able to store important info as precise variables, and create new objects and cuts and stuff just with for loops and if statements.

I use the web version a lot of the time, and while it could use a little work, it's pretty amazing.

Couple I've come across recently and haven't seen here yet:

micro - a nano-style terminal text editor with modern features and plugins.

termscp - a terminal FTP (et al) client heavily inspired by WinSCP.

ubuntu touch, its actually at a usable state

Gnu Guix. By default Guix uses only free libre software, but there are ways to install it with a non-free kernal. Systemcrafters has a guide (this is what I used) as well as non-guix (guix repo for non free software).

Immich. Just found out about it, still gotta try, but looks good, an app that allows you to configure a Google Photos like app locally hosted, with automatic phone backups
