I was looking for a good and quick file transfer method and stumbled upon Warp on Linux (flatpak). It says the app is open source but I did a quick Lemmy search and someone mentioned the protocol magic wormhole is closed.

Even though I found the application very useful, like I can transfer files even when connected to a VPN service, the closed source nature turns me off.

Also when operating without a VPN, wormhole connects via local network, my desktop is behind a firewall, but the transfer still happen! How does it do that without opening a port in f/w?

Any alternate suggestions are welcome as well.

Edit 1. The domain for the magic wormhole relay and transit server that most open source clients (like Warp) use is magic-wormhole.io. I have to check if they really are open source.

Edit 2. There seems to a mention of the magic-wormhole.io domain in their PyCon 2016 presentation.

can you link to the post that claims the protocol is not open? I'm interested in looking into that
anyway, source for the magic wormhole can be found here: https://github.com/magic-wormhole/magic-wormhole which also links to both the Mailbox code and the Transit Relay code.

I think that wormhole.app page is different software from magic wormhole (and warp). It just has a similar name. wormhole.app does appear to be proprietary.

Warp uses magic-wormhole.io and my android client uses the same domain for its Rendezvous and Transit servers. I am still learning about what they really are.

So I think the mentioned URLs might be closed source, I don't know. But the default ones that warp use is this magic-wormhole.io (relay and transit) seems to be open source ones.
