It's 2025 - Why Is Offline File Sharing Still So Broken?

Aero on June 28, 2025

AI is writing code, smartphones rival space shuttles and we are streaming 8K from our wrists. But sharing a 200MB file with someone in the same roo...

what if we make a web app using express and serve it on local host.I think it should be working even while internet off.Plus, we can make the interface in our own way(no login and pass keys).
And the serving pc may be of any os, the user devces will get a consistent file sharing env.

It will work when one of the devices is a desktop. How about sending between 2 different mobile devices?

Yeah, that's a problem.
Ok, there is an app called warpinator (you may know) that we can use between pcs' and mobiles.

Fair enough. But as far as I remember, there is no "official" ports for Android or iOS or Mac.

I have been using it on android and linux. Its works well!
But, don't know about mac!
Lets see in future,if it gets mac support or maybe some other app that fills the need and gap!

Let's hope something fills that gap. Cross-platform file sharing is a mess these days - if you don't go the cloud way, that is.

tbh, I had some plans for building a file-sharing app with cross-compatibility between different os but it got scrapped. now that I read this article and also I've got quite fluent in KMP, you've kinda convinced me to build one such. I'll see if I'm able to build one after my current projects get done. fingers crossed.

this hits home, honestly. every time i run into this in person, i wonder if anyone at those big tech companies even cares about real-world file sharing. you think the lack of offline-first tools is because nobody sees profit in it, or is it just not on their radar

Or the cloud integration may have become so ingrained that it's just not a concern anymore. Let's face it, cloud integration brings in more data, but what about the lack of cloud? There used to be more offline-first apps that just worked. Where did they go?

Totally feel this - the amount of times I've tried to send a big file in person and ended up wasting way too much time is ridiculous. Have you found any local-first apps that actually get this right?

Right? Currently, I rely on the good old USB. I'll give an update when I find one
