Hey,

I was wondering what folks use to quickly send a file or a link between your PC and android phone in a lightweight and self hosted way.

Currently I use syncthing to copy files around, but I'm looking for something more immediate, and quick than doesn't involve searching for folders in a file manager.

Example use case: Send a file from PC to phone. Notification pops up on phone, tap it to access.

(PC runs OpenBSD)

What lightweight software do you guys use?

Stuff I tried so far:

  • syncthing
  • xmpp
  • tox
  • scp and termux.
  • magic wormhole
  • telegram saved messages

Do you have any hosting in your home lab? Preferably something for running a docker container, but a hypervisor could do the job too.

Nextcloud is an option if you do. Technically speaking you could properly protect it and make it public. You don't have to do that though. Any file you upload on your computer could be copied to your phone or vice versa. If it's public, then this could be done from anywhere.

[–] [email protected] 1 points 6 days ago (1 children)

Yes, I have a Linux vm for docker. I've chucked up a pairdrop container. So easy.

[–] one_knight_scripting 1 points 6 days ago* (last edited 6 days ago)

Can't say I've used that... Yet. I like nextcloud because besides being compatible with Linux/Windows and having an Android app, it also has a simple web UI to access the files. It's probably closer to self hosted OneDrive than anything else I can think of. Kinda like the simplicity of pairdrop though.

[–] [email protected] 50 points 1 week ago (1 children)

I love localsend.

Works on Linux, Android, iOS, Windows, and Mac. It is basically an OS agnostic Airdrop.

It's FOSS, so you can go to the Github and build from source for OpenBSD, but I have no idea if that would work.

[–] [email protected] 5 points 1 week ago (2 children)

Dart (the language it's written in) doesn't work on BSD, so sadly that's out of the question for now.

[–] [email protected] 4 points 1 week ago

Dang, that's too bad. Hopefully one day!

Here are a bunch of local services I’ve used at one point or another from phone to PC or PC to PC. Not sure if any links are out of date.

KDE Connect

Wormhole (Closed Source)

LocalSend

SnapDrop

ShareDrop

FilePizza

Original Wormhole

PeerTransfer

JustBeamIt

Send Visee

[–] [email protected] 22 points 1 week ago (1 children)

+1 for LocalSend. Well worth checking out.

[–] [email protected] 8 points 1 week ago

Another +1 for it here. Use it multiple times a day between Linux, MacOS, android, and iOS.

[–] happinessattack 16 points 1 week ago

+1 KDE Connect. File transfer works great on Android, Linux, and even on Windows 10/11! Clipboard sync is also a game changer; super easy to copy and paste across devices.

[–] [email protected] 6 points 1 week ago

+1 Love LocalSend!

[–] [email protected] 3 points 1 week ago

PairDrop is a fork of SnapDrop, which at one point had more features and active development. Don't know, how it is nowadays though.

[–] [email protected] 39 points 1 week ago (3 children)

I usually use kde connect.

[–] [email protected] 11 points 1 week ago (1 children)

KDE Connect also works on Gnome, Windows and Android. I can't recommend it enough. Transfering a single image from phone to PC is instantaneous

[–] [email protected] 4 points 1 week ago

And having a unified clippboard is just so convenient

[–] [email protected] 3 points 1 week ago

Yeah, me too. It is quick and easy. I use SyncThing for things I want to keep synced.

Kdeconnect. Alternatively NextCloud or sending an email to myself.

[–] [email protected] 3 points 1 week ago* (last edited 1 week ago)

Seconding sending an email. SMB for big stuff.

[–] Deckweiss 12 points 1 week ago* (last edited 1 week ago) (3 children)

https://pairdrop.net/

open source, can be self hosted or you can use the official instance.


Personally I have been using KDE connect most of the time when I am at home.

Pairdrop I use more when sharing with other people across the internet.

[–] [email protected] 3 points 1 week ago

Never heard of that tool. Thank you for sharing it!

I use KDEConnect. I don't know about iPhone but it works with Android, Linux and Windows.

[–] [email protected] 4 points 1 week ago (2 children)

I have tried to use KDEconnect over and over, It doesn't work on my work network, it doesn't work on most of my home network, If my laptop my cell phone come up as different IPs it gets confused. It's discoverability is just absolutely horrible except for a select number of plain vanilla networks.

As I have basically all devices connected to my Nextcloud instance, I simply use that. I don't have any "time-critical" file transfers though.

[–] [email protected] 4 points 1 week ago

Well my transfers aren't "time critical" either, but life feels easier if I don't have to jump through hoops to solve a task that involves copy files around.

Re: next cloud, looking for something more lightweight than that.

[–] [email protected] 5 points 1 week ago (2 children)

I mean, the fastest method is likely to just plug the phone into PC and pretend it's a flash drive?

[–] [email protected] 5 points 1 week ago (2 children)

From memory MTP is pretty flaky and quite slow.

ADB push is pretty good but at that stage rsync is just as easy.

Put SSH in the phone and you can do it all from the computer too.

For more manual stuff; Ssh and X-Plore File Explorer.

Internal, sd card, ssh, ftp(s), google drive, dropbox, and a bunch of other cloud providers; treats it all like one big file system that I can casually copy/move files between.

For just syncing files between folders: FolderSync. The 'downloads' folder on my phone is setup as a 2-way sync with a folder on my server. Drop a file in either side, click sync, file is in both places. I use this to keep most of the files on my phone backed up, not just syncing the download folder.

FX File Explorer has a local web-access feature. Start it on your phone and access via local IP, then just turn it off when you're done.

Don't use on public wifi, it's http-only.

[–] [email protected] 5 points 1 week ago* (last edited 1 week ago)

Syncthing is fast. I have an IPv6 setup too which seems to help.

I have my downloads directory on my desktop linked to a downloads directory on my Android; you can't link to the real Android downloads directory anymore so I use another.

When the file is removed from the desktop downloads directory it disappears from mobile.

I tried using Bluetooth between them but it's more fiddly than Syncthing with my config. Switch Bluetooth on on desktop, connect to desktop, send file, disconnect, move file. Whereas Syncthing is always on.

However, before I started using Obsidian notes I used to transfer URLs using Signal's Note-to-self thing. Signal on both desktop and mobile.

Obviously, I sync between mobile and desktop Obsidian using Syncthing.

Taildrop works relatively well for most all circumstances. Only thing is you gotta use trayscale or cli currently for sending files from a Linux/bsd machine. I don’t know if opened has a port for trayscale but it definitely has a port of tailscale.

[–] [email protected] 4 points 1 week ago* (last edited 1 week ago) (1 children)

I use pairdrop. I don't personally self host it, but that option is available. It's better suited to more one-off situations, as there's no history kept anywhere.

Selfhost: https://github.com/schlagmichdoch/pairdrop

Open instance: pairdrop.net

[–] [email protected] 3 points 1 week ago

Not heard of this one. Thanks.

[–] [email protected] 4 points 1 week ago (1 children)

I often spin up a quick python http server. Just go to the folder which has the files you want to transfer and run the following command: python3 -m http.server. This will server the folder content Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) .... On your phone you can then browse to http://PC_IP:8000 and download what you want/need.

I've tried LocalSend for this, but I usually end up using more reliable ways like Syncthing (not instantly transfered, but at a decent speed) or sending myself the file on Element for Matrix (as good as instantaneous).

[–] [email protected] 4 points 1 week ago

I use QuickDAV and OwlFiles.

[–] [email protected] 4 points 1 week ago* (last edited 1 week ago)

I use Cx file explorer and mount my PC via sshfs in there. It's closed source but it supports a whole bunch of protocols including samba, ftp and webdav. And it can launch a webserver on your phone to offer the phone's files. But sshfs is the most convenient for me.

And for links and other small texts I use either KDEConnect's copy and paste sync or just send myself the text in Signal.

[–] just_another_person 3 points 1 week ago

I'd use anything else that is based on rsync over Syncthing

[–] [email protected] 3 points 1 week ago* (last edited 1 week ago)

SFTP or Matrix

[–] [email protected] 3 points 1 week ago

For a single file, I just use Bluetooth. For a lot of files, or a really big file, I plug my phone into the PC and set it to storage device.
