A comment on Siggo: A terminal GUI for signal-CLI, written in Go.

Can someone shed some light on the landscape here? I thought there were only 2 possible ways to use Signal; the mobile apps and the desktop. Is this CLI app somehow talking to them? If anyone can make a client, then what's stopping someone from building better mobile apps and indeed a web client!? Other than of course the sheer effort that's involved obviously.

This uses signal-cli[0] (communication happens over D-Bus) and signal-cli in turn uses a patched version of libsignal-service-java[1]. The latter might be used in some of the clients provided by Signal (not sure) but the signal-cli + libsignal-service-java combo talks to Signal servers instead of any apps running locally.

Nothing is stopping you from building a web client for yourself.

I guess libsignal-service-java might be used in the Android app?

That's what I was thinking too but then last commit was 7 months ago. Not sure if any of the latest features would have required new code in libsignal-service-java though.

The CLI is Java and probably not well documented.

In the past I think Open Whisper systems have been hostile to third party client builds interacting with their servers, so I'm not sure they'd welcome third party client implementations.

I mean, as soon as third-party clients were a thing, the Play and App stores would be immediately clogged up with Signal clones left right and centre, all of which steal your data and then ??? it.
