Note that it's less clear how secure croc is. Magic Wormhole would be the reference there, I think. I have seen issues on the croc repository regarding security, not sure what the state is today.

Granted croc supports resuming transfers, which magic wormhole doesn't.

I've used croc extensively and had no issues.

100% endorse croc, you can use croc in any GPU renting service (e.g Runpod).

coc is also available on android which maked it really useful. Although kde connect works very well at least for smallish files, it requires pairing devices you might not want to pair permanently.

croc's throughput was also a lot better for me. I think this is due to them using multiplexed TCP streams.
