Localsend: An open-source cross-platform alternative to AirDrop (github.com)
eigenspace 14 hours ago [-]
My problem is that all these alternatives require the devices to be on the same local network.

One beauty of Airdrop is that it creates and handles that local network automatically under the hood (as far as I understand). So you could be out on a hike with friends and Airdrop something.

The workaround I've found after switching to an Android device has been to teather my connection to my friend's device, which ends up creating a LAN that Localsend can work through, but this is not as nice an experience.

Device to device transfer, just a static github page.

gh repo: https://github.com/mbarlow/thinair

Creates QR codes for each device to scan for webrtc. Android to android will do an audible chirp that lets the devices know to switch from qr code mode to opening the camera to scan each others codes. Tested android to apple and working, the audio chirp doesn't get caught by apple. Just wait and eventually the qr code will dissolve to allow scanning step.

Just threw this together. I was playing with audio handshake using bird-like chirp "songs" or old school modem between smartphones. Fun putting phones together as they send audio frames and confirm to start transfer, but unreliable and slow to handshake. I would like to cleanup the flow to improve. I've started using it for sending files between iphone/android/pc without having to deal with apps, emails, accounts, etc. blah.

This is using webrtc and speeds are slower than a physical USB I get 3-4MB/s instead of local network speed of 30MB/s due to browser browser implementation bottlenecks. I needed fast local network sharing of files over 5GB and tried a lot of approaches and speed doesn't budge more than 6-7MB/s .

Also you don't even need a server atleast for now in chrome webrtc transfer can work over a file:// in firefox it doesn't. For signaling you could even use free peerjs tunnel or other when user is connected to internet and otherwise fallback to this QR or offer code sharing. This will become so useful if browsers eliminate those bottlenecks.

also even in localsend speeds are limited usually to my internet speed for some reason.

nomel 6 hours ago [-]
Whenever I need to use something like this it's because the device isn't mine, which makes this so much better than an app. Would be cool if there was a text message option, and a bit of server so the second scan wouldn't be required. Pretty funny how simple the concept is though.

Make sure to also try PairDrop https://news.ycombinator.com/item?id=47935875

It's a pretty polished PWA you don't even need to install as it uses WebRTC P2P streaming in the local network or via TURN over internet.

So a good solution for ad-hoc file sharing without ad-hoc network.

Airdrop is also pretty weird: sometimes it can’t find other phones (probably when a previous transfer failed silently in the background). Also, it had some issues searching for contacts when there was no mobile/Wi-Fi connection (tried to send photos to another phone in the mountains). Sometimes it could just freeze and not work… Apple magic here isn’t really useful.
WhyNotHugo 12 hours ago [-]
Indeed, Localsend only does the last step of what Airdrop does. With Localsend, you need to:

- Create an ad-hoc Wi-Fi network on one device.

- Connect the other device(s) to that Wi-Fi network.

- Now run Localsend.

The first two steps are a bit of a drag, and the fact that Airdrop handles it is what makes it so frictionless to use.

giobox 11 hours ago [-]
Right, the first two steps are what make AirDrop, "AirDrop". This isn't an alternative at all if it requires both devices to already be connected to the same WiFi.

AirDrop is fantastic for sharing files with people you don't know/just met - if we have to find and agree to join the same wifi before we interact we are no longer talking about the same feature.

If Apple's AirDrop implementation had required people to join the same WiFi first, the feature would never have taken off the way it has among non-techy users. I'm still today mildly surprised I can use AirDrop as a verb in conversation and most of the time the other party knows what I mean.

nine_k 11 hours ago [-]
Speaking of ad-hoc communication channels that do not require shared infrastructure: I like the idea of https://github.com/divan/txqr which sends data using animated QR codes. An ultimate guarantee of physical proximity. The bandwidth is not comparable to WiFi 6, of course, but no OS support is required.

Not only that, but with iOS 17.1 or later, AirDrop transfers will continue to work if you go out of Wi-Fi range during the transfer. It seamlessly switches to an Internet-based relay.

Which, in my view, significantly decreases the value proposition, as there is no way to deactivate this feature to my knowledge (at least not without also opting out of other useful features under the "Handoff" umbrella).

A typical Apple feature, dreamed up by engineers that are presumably not aware of the existence of metered data plans...

sholladay 5 hours ago [-]
You can disable it, actually.

Settings > General > AirDrop > turn off Use Cellular Data

That said, I don’t really see why you would disable that. It’s only a backup method for when the peer-to-peer connection fails. Unless you are sending huge files on a regular basis, I wouldn’t expect it to be worth disabling. Also, most metered plans I’ve encountered just cause your connection to be very slow after you hit the data cap.

If you are on a plan that automatically charges you excessive overage fees without warning and there is no other choice, then my condolences.

Oh, cool, thank you! I must have used the wrong search terms; I could only find vague hints about deactivating Handoff/Continuity.

I do use AirDrop extensively for sharing photos when traveling. One sharing session could easily eat through my roaming allowance.

Bluetooth is also very slow. Airdrop and Localsend achieve speed by using local wifi networks. The problem with Localsend is that the user themselves need to manage the creation of the local network.
askldfhalkdfh 12 hours ago [-]
This. Localsend may be very useful for a set of devices you control or influence. The USP of Airdrop is ad hoc sharing with people you don't really know. Classic case is meeting strangers on holiday and you want to swap some photos of the trip you're on. One or both of you doesn't have data or time to install anything, or it's just too hard to persuade someone they should install random app. Pairing Bluetooth or setting up local networks is way too convoluted and time consuming.

With Airdrop you have trivially easy, "just works" sharing with people in proximity. It works great between iPhones and Pixel phones now they support it. It just needs support to spread to more Android devices.

davely 12 hours ago [-]
> With Airdrop you have trivially easy, "just works" sharing with people in proximity.

Funny enough, I encounter so many problems trying to share things via AirDrop with friends, family, and even my own Apple devices that I just tell everyone to install LocalSend and I find that things work better.

I’m not sure why that is, because AirDrop used to work pretty well for me. But it’s been an exercise in frustration more often than not for me.

(Obviously, LocalSend works only as long as everyone is on the same network.)

It is entirely possible to inject (unrelated) wifi frames while being associated to a BSS without violating the existing 802.11 standards. That’s why Apple is able to implement AWDL on standard compliant wifi hardware.

However the path towards this type of interoperability would likely go through additional standardization via IEEE 802.11* and the Wi-Fi alliance. At which point Apple will need to implement and support the new standards. There is no need to reverse engineer AWDL to meet the new European interoperability requirements. What is needed is for wifi chipset OEMs to implement such standardization. Something pretty routine of them.

It can be expected that Apple will also maintain the proprietary AWDL in order to support their legacy devices.

Maybe a network nerd can chime in - is this implementation so difficult that it's unrealistic we'll see an OSS version?

granthum 12 hours ago [-]
I think the thing that makes an OSS implementation more difficult than iOS/macOS is the friction involved.

Say you've got an android phone, windows PC, and a linux box, and you want to be able to quickly drop files from each one. unless we get some kind of cooperation across all three platforms at the OS level, you'd at minimum need to install some kind of client into each system - when the nicest feature of airdrop is that it's baked into all of Apple's OSs, in my opinion. even if it worked exactly the same way, but had to be installed, I think it would see less use - and there's no real way for a single OSS project to do that across multiple OS platforms, to my knowledge

lxgr 9 hours ago [-]
The physical layer part really isn't complicated, and most Wi-Fi chipsets have supported something like it for over a decade now.

What's tricky is to specify and get everybody to implement the layers on top of it, including device discovery (frequently offloaded to Bluetooth for efficiency reasons), user identification (Apple runs a PKI for this) etc.

This is really nothing special as 802.11 implementations go, as it's pretty easy to do as long as you can control the physical channel for at least one side.

Many Windows, Linux, and Android devices have been supporthing this for years. It's usually called something like "simultaneous AP/STA mode".

lurker24325 13 hours ago [-]
This is misinformation, including most of the comments here, the majority of phones from 2014 support Wi-Fi Direct, and simultaneous group and station mode (2 BSS, yes even different channels). Even most Wi-Fi chips generally not just smartphones for a very long time. They stay connected to your home network.

When Quickshare drops your Wi-Fi connection, its not Direct anymore, that's just soft AP from an error, and if that doesn't work, it fallback to Bluetooth. Bluetooth is used for provisioning as well.

The only reason why many apps don't use it is because of buggy implementation, some phones require a full restart after using Wi-Fi Direct to fix connectivity issues, even Motorola's own product line with Smart Connect use it only with certain models, despite having Wi-Fi direct due to poor implementation (can be forced). They even have a white list of supported adapter for the Windows app since direct is used as well, can be unofficially force enabled for Mediatek based adapters (rare on some laptops).

Back in 2016 things were much stable on Android phones with Wi-Fi Direct, even with old Blackberry, there were many apps including file managers that used it before it was essentially dropped, even for onboarding/provisioning apps like HP printers...

Apple's Airdrop success is about gaining traction, in the era of Wi-Fi Direct or other methods, most people were not aware of such features, as it required an app to be installed, they used email/messaging, even when Airdrop was first introduced and preinstalled, it took years for the average person to use it.

I'm curious, what do you people use this for? What are all these (presumably large) files that you guys are generating and transferring, that requires the use of apps like these?

Like in my case, the only files I generate on my phone are photos and videos, and these get backed up by Immich, which I can then share with someone by sending them a link to the files/album in question. I imagine normal folks would use iCloud or Google Photos for the same task.

For syncing other files like documents and such, I use ownCloud OCIS, and I'd imagine most other folks would use something like DropBox or iCloud, or even just email or WhatsApp the files.

For local network transfers of say ISOs or something, I'd just copy them over SMB, which is pretty much universal and doesn't need any special app. Or even just plug in a hard drive, if I'm doing backups.

So I don't understand why I should be using this.

Sending someone a link to a photo is a much worse experience than sending them the actual photo directly to their phone.

Sending a photo over text message often compresses it, which isn't always desirable. (Not actually sure if it gets compressed when sent of iMessage)

OGWhales 14 hours ago [-]
Yup, for me I can see the device but when I try to initiate a send it just doesn't show up on the other device about half the time. I've not found a reliable way to fix it either, toggling AirDrop on and off on both devices seems the best way to fix it but only works like 70% of the time.

Look into Sendme [0] and AltSendme [1] (which is a GUI around the former), they use Iroh [2] which is an open-source encrypted peer-to-peer relay service to send data so there are no limits whatsoever for sending and receiving files, because there's no central server.

This kind of services that requires the user to share a seed/code to the recipient always seems kinda awkward to me. The code is not simple/short enough to be verbally communicated; If I can send the code, I usually can just send the file.
satvikpendem 10 hours ago [-]
Not necessarily. For example I might have a few gigs of photos to send someone, and I want to send them uncompressed. I could text someone the seed or QR code for them to download the photos, but I can't send those photos (especially uncompressed, even if over RCS or WhatsApp) over text.

Hi,

I am late to the party, but I was also building in this space in the last year,

Basically I did a peer to peer filesystem named keibidrop: https://keibidrop.com/

I made it public last week. It does what local send does, but also via WAN. Still did not launch the mobile apps.

And 1 up is that it has also a virutal filesystem that is synced both ways.

repository is here: https://github.com/KeibiSoft/KeibiDrop

The code is open source, except for the UI, and I did benchmark on loopback vs localsend (local send is faster :D )

https://keibisoft.com/blog/keibidrop-benchmarks-vs-competiti...

and was also trying to get a commenting thread in /r/golang yesterday!

behind the hood I went with PQC, + gRPC + FUSE.

I use it on all my devices and tbh it's the absolute best option I found.

Previously I was using syncthing or had to install ftp server, used wormhole after packing all my files into one, etc. Android QuickShare never worked for me (wouldn't help me much with sending to the pc either).

It has some rough edges (ie: on multi-homed devices it's less that ideal to see the one octet that matters, when the list is very long scrolling whilst sending will cause the process to crap out), but other than that it's always reliable.

I'm very happy with it too.

Shipped something similarly-shaped on Tauri instead of Flutter. Concrete numbers from my installers: ~27MB on Mac, ~45MB Linux .deb, ~53MB Windows, vs Electron's ~150MB floor. (.AppImage is the outlier at ~110MB — it bundles the runtime.) The size reduction comes from reusing the OS webview, which is also the cost: WebKitGTK on Linux behaves genuinely differently from Mac WebKit and Windows Edge WebView, so you spend the engineering time on cross-platform debugging instead of getting it free from Chromium.

The thing that actually surprised me wasn't framework choice though, it was Linux packaging. AppImage runs everywhere but feels second-class to most users. .deb covers the dominant distros but you're tracking a moving glibc version. Snap/Flatpak are the "official" cross-distro answer but their sandbox and permission stories burn weeks for an indie. I shipped .deb + .AppImage, and the "Why isn't this on the AUR?" emails started within hours.

LocalSend is the best app to transfer files from mobile to computer wireless that I have fund.

But it has one really big weakness/bug. When you transfer a file and it get interrupted, the half written file on the receiving end is not removed and you get an corrupted file. If you dont notice it, it could look like al files are transfered, but they are not. This is really bad, it is not how files should be "copied/transfered".

This has been on my mind a lot as AirDrop has continuously failed to find devices on my network (no VPN enabled on either device, no weird routing or tunneling, even after flushing networking stuff).

No. It is using a central “well known server” and requires internet.

Test:

    * Does it work in an airplane?
    * Does it work in a submarine?
    * Does it work in the mountains, when a thunderstorm is approach and you need to share the GPX?

Basically my Garmin Edge and iPhone can do this. Magic-Wormhole fails in all test cases.

Implementation shall be able to negoiate a connection locally (e.g. Bluetooth) and upgrade to peer-to-peer WiFi if need (Garmin doesn’t need that part, GPX are usually smaller than 1024 KB).

Modifications can be made to do that minimal peer exchange over BT. They may already exist, but I haven't used that part yet.

For years I have been syncing with great success using the most basic FOSS tools: `rsync` over `sshfs` on desktop, and SSHD (via an app called Dropbear available on F-Droid) on mobile, using an ad-hoc network over the wifi hotspot (which is turned on by Macrodroid - alas not FOSS - when the device is plugged in). This setup is rock-solid reliable and very fast.

To send files locally why not set up a wifi hotspot?

Then you can transfer files to and from uncool people with Android or Linux phones/computers using localsend.

I've never found this difficult and often use hotspots when I'm overseas - it's cheaper to get internet for one phone and share it with the others for example.

Also zero-knowledge logins (via OPAQUE), passkey/2FA support, no AI training now or ever, GDPR compatible. 2 GB transfers are free.

Blip definitely has a better UX and it's nice that it can transfer between networks through their servers (obviously don't be sending sensitive stuff cause who knows how much they can be trusted)

But I consider my usage of it to be on borrowed time cause there's no way they're gonna let everyone forever beam unlimited data through their servers forever. They're accumulating users before they make you pay, it's just a matter of time. But I'm enjoying it while I can.

Because none of them actually match the capabilities of AirDrop, since they essentially require controlling the full stack (UI, low-level networking including Bluetooth for discoverability, Wi-Fi peer to peer connections without dropping any existing infrastructure connection etc.)

Many have tried, I don't think anyone has succeeded.

Supposedly the EU interoperability mandate will make this possible going forward, though? (The tricky part is usually not getting your device to speak some protocol, but to get Apple devices to actually respond to your attempts.)
