Selfhosted

I'm not sure if there's one the best tool, depending on a case, I use mix of

• scp
• localsend
• croc
• https://github.com/dutchcoders/transfer.sh
• https://github.com/stonith404/pingvin-share
• pbcli (pastebin)
• I also have a script that sends me mail with files attached

Syncthing or https://pairdrop.net/

My solution is scp with termux. I can't suggest any better alternative.

Open source file manager Material Files lets you set an SSH server as a bookmark and mount it instantly. Moving files around just like like it's native. Works seamlessly through Tailscale.

Signal

I'll add in Bitwarden Send (including self-hosted vaultwarden), although probably doesn't make sense if you're not already using it for password management.

rsync -avr --progress in termux or a file explorer app built on top of scp or rsync. It doesn't work like your use-case, but I've been happy with it.

Android -> other I often use Share via HTTP.

This sounds great. Thanks.

For single files, I use qrcp

I use ADBFileManager https://github.com/T0biasCZe/AdbFileManager/ which is much faster than MTP

In my testing, the program copies files at speed of approximately 41.6MiB/s (332Mib/s) over USB 2.0, compared to MTP that copies at around 10Mb/s

I ll just hijack this thread : when plugging my android into laptop, the laptop doesn't recognise it as anything. And the phone doesn't give me the option to "share files" instead of just charge. Does anyone knows what's wrong?

I didn't see it mentioned yet, so I'll throw warpinator in the ring.

Clients are available for Linux, Windows, Android: https://warpinator.com/

For links, I use Pocket (you can use Wallabag, but I find the interface not efficient at all). For files, you can sync a folder with syncthing (but you only switch it on when you want a quick sync, otherwise keep it off for battery). If you just want to put some file on your phone, install FTP server (free) from F-droid and switch it on when you need it (there's even an optional switch on quick actions). Use Filezilla or any file browser (if on Linux) to exchange your files. Remember to switch the server off once finished, because FTP is not a secure protocol.

I use SyncMe which synchronizes smb shares to your phone. It's great once you have it set up, but it does take a little setup. Gotta have shares and whatnot.

Does your PC have Bluetooth? Definitely quick and sort of self hosted.

KDE Connect as another uas suggested.

Only buggy issue I have is that I use a VPN on my phone to access my local network when away from home. I have the VPN set up with Hairpinning so I don't have to disconnect from the VPN while at home which occasionally causes issues on my steam deck as the version of KDE Connect on the steam deck does not appear to have an easy way to connect to device via IP. On my desktop and laptop I run Pop!_OS and use GS Connect which gives me an option to connect to device via IP so I have less issues with my phone just randomly not appearing on those computers.

I'm using a selfhosted pastebin (microbin) as sometimes I want to transfer text, other files... It's very efficient and in my instance it's using 13MB of RAM, which is fairly lightweight for modern standards

sftp

You got some good replies and I personally am enamored by LocalSend, it is worth checking it out.

However, there is a simple way if a) you use whatsapp and b) the devices involved have access to whatsapp.
This involves not just sending files but you can send text and whatever whatsapp supports and you'll have a history of these chats should you need to have them later again. Probably possible with other platforms but I use whatsapp so that is what I setup for information transfer to myself.
The thing you want to do is create a chat group, add a friend for a very brief moment, remove said friend again after they accepted, enjoy your private group where you can dump any and all info into and pick up from wherever you have whatsapp available. The trick is to add a friend for a couple of seconds. If you create a group you are automatically in it but you cannot use it until you add someone else, then it becomes active and use-able. The fact that you end up alone in that group does not make it unavailable again. Weird but it works.
