Not sure how important this is to anyone, but this does look as though it was heavily leveraging Claude and Cursor. May not be a bad thing, depending on the dev's usage of those agents, but I do think it's important to know.

regardless of whatever else you think about AI, it's a good idea to be very wary about security-sensitive apps that are written using LLMs.
there's a self-hostable S3 replacement called RustFS, with development that leans heavily on LLMs.
they had a security vulnerabilty last year.
one LLM-written commit added a complete authentication bypass to the code. literally, you could just send rustfs rpc as the auth token instead of an actual token.
it was fixed in a pull request named fix: Prevent panic in GetMetrics gRPC handler on invalid input which claimed to fix a different auth problem and just coincidentally removed the hardcoded auth token.
security stuff is hard, and LLMs are prone to over-confidence. that's a bad combo.
“Think of it like AirDrop for any device, any network”
Not available on iOS. False advertising much?
KDE Connect?
Not always work, specially on windows is so bad, but it is tolerable, they have made a lot of contribution to open source environment.
I use Localsend. Should I be using g something else?
Nah, it's fine.
I like wormhole
There are so many open source solutions to it at this point, yet nobody has thought of simply aggregating all of the various solutions into one with a simple GUI/CLI basically asking "Do you want to send it directly (P2P E2EE), indirectly (through agnostic server to hide IP), upload it (3rd part account/server needed), or make a share (announce your hash and IP on a discover network)?
Any reason I should use this instead of the 3k other similar products?
I have no such app installed. Which foss app is currently the most promising/successful/widely used one?
If there are so many, maybe it's time to work together ..
I use https://getcroc.com/
Other suggestions in this subthread assume existing direct connection, this doesn't.
Other comments mention Magic Wormhole and wush, didn't try those, probably work too
Local Send (if both divices ame in the same WiFi)
Sftp? Rsync?
KDE Connect
KDE Connect works over the Internet?
This is like a torrent. File sharing works as long as you keep the website open.
scp
Why is the universal Android Version 160MB?
Like everything these days... devs are not interested in saving storage.
Can someone compare this to Magic Wormhole for me?
After some reading it looks to me like the biggest difference is that Dashbeam uses an established peer-to-peer system (Iroh), and can operate without servers. Magic Wormhole uses servers instead of a peer-to-peer network to set up connections. Magic Wormhole requires a "mailbox" server to negotiate a connection, and may require a relay server for NAT traversal.
Dashbeam might also use a relay (I'm not positive about this - relays are described in the Iroh docs, and I don't know for sure whether Dashbeam uses them). But Dashbeam advertises NAT hole punching that might avoid use of a relay in more situations. That should lead to higher transfer rates since you're not limited by the bandwidth of a relay run as a public service.
Dashbeam doesn't use a mailbox server. The trade-off is that Dashbeam "tickets" are too long to read over the phone, or to type in by hand. Magic Wormhole's pairing codes are designed to be short for exactly those use cases.
Dashbeam has mobile apps, ~~it look like Magic Wormhole doesn't.~~ Edit: looks like there are mobile apps after all!
So it looks like the advantages of Dashbeam are:
- potentially faster transfers
- doesn't rely on publicly operated servers
- appeal to fans of peer-to-peer protocols
- mobile support
And the downside I see is:
- you need an existing digital channel to send a ticket to set up a connection
Compared to some other services, like Pairdrop.net, it looks like Dashbeam might not have automatic local network discovery.
Another advantage, according to them, is this software allow people to resume downloads/uploads and it is a plus over kdeconnect or simpler clients like lanxchange (no one knows this last one).
Another point is they allow to share folders, some clients like this do not allow that.
Magic wormhole has 2 that I've found. This could be interesting though.
Thanks, internet friend! ❤️
Oh nice; thanks for pointing that out!
You're welcome internet friend!
How does this compare to wush?
DashBeam has gui haha
So it's worse?
If you are a normal pc user, no. If you are a hacker, yes.
Anyone want to explain why / if I should use this or syncthing?
Syncthing is a file syncing service. This is a file transfer service.
Dashbeam is more for occasional transfers, it seems. You want to send me something right now, you use Dashbeam.
Syncthing (which is great and I use) is more for background sync between devices. I use it to sync and backup my important documents automagically between my devices.
So, Syncthing is definitely great and you should use it, if it fits your usecase. I don't know about Dashbeam (in the sense of whether it actually works or not), but the usecase seems a little different.
Yes this seems like more of a LocalSend alternative, but with the added benefit of working over the internet so you don't have to be on the same network
I haven't used this but from their website / description it looks like they are more of a on-demand file transfer service, e.g. they are comparing themselves to Magic Wormhole, PairDrop, LocalSend, etc.
Syncthing has its roots in being used for automatic file/folder synchronization, that's its strength. But sure, you could set it up for a one-time file transfer too if the other person is willing to set up Syncthing on their end.
DashBeam does seem to be able to do transfers via web browser, that could be an advantage if the person you want to transfer something to/from does not want to install anything extra on their device.. but I don't know how well any of that works in practice.
Good question, the actual idea for both is a great one and not something I was aware of.
Looking up an actual comparison, I can't find one yet since this is so new, but perhaps that's part of the plus, since new might mean better transfer process and speed, security, etc. Old isn't always a bad thing, but some commentary I ran across looking for alternatives to Syncthing was because it had limitations they ran into due to it being designed for specific needs and not general purpose?
