docs VS Spectrum 2

I'm unclear if it supports relay mode, but if so, you can invite Matrix, Signal, and WhatsApp users into the same group chat! [1]

I've been using this on my self-hosted version of the bridge and it does wonders for those friends who are on Signal but don't want to try another app.

Also, a lot of people just don't want to swap between apps for direct messaging people on different services. This means you can use any Matrix compatible app [2] to chat with anyone on Matrix/WhatsApp/Signal/Telegram.

If you have a matrix homeserver you could run whatsapp in a virtual machine and bridge it to matrix. https://github.com/mautrix/docs/blob/master/bridges/go/whatsapp/android-vm-setup.md

This is the point where I lose everyone and a big reason for this is that people don't understand how libpurple works with Pidgin, Finch, Adium, bitlbee, spectrum2, telepathy-haze, and maybe others I'm not aware of or forgetting. So that's what we're going to try and tackle today.

Turn any XMPP client into that fancy multiprotocol chat app that every cool kid want.

> Signal, Telegram, Discord, Steam, Mattermost, Facebook, Skype

Spectrum is an open source instant messaging transport. It allows users to chat together even when they are using different IM networks.

https://github.com/louiz/biboumi

Biboumi is an XMPP gateway that connects to IRC servers and translates between the two protocols. It can be used to access IRC channels using any XMPP client as if these channels were XMPP MUCs.

------

I'm using all of those daily to connect to all my other accounts, Slidge is the most modern one and is having lots of features ported to the modern XMPP extensions.

It's actually closer to spectrum2 in how it behaves. I hope slidge will get as rock-solid as biboumi is!

I want this to take off. I'm tired of having to follow trends: IRC to ICQ to MSN to Skype to Google Talk to Facebook Messenger to Whatsapp to Signal.

Pidgin is good (I also miss the ancient Trillian, even though it was closed source), but limited to a local device.

There are XMPP Transports as well for these (see https://git.eta.st/eta/whatsxmpp , https://gitlab.com/nicocool84/spectrum2_signald , but sadly https://spectrum.im/ is surprisingly finicky to set up.)

There are at least hundreds of implementations of XMPP that are interoperable (at 5-6 actively developed server implementations, many more libraries and many client applications). There are at least hundreds of thousands deployed XMPP services.

In addition XMPP can be linked with other protocols/networks via bridges/gateways. Some examples:

- Spectrum: XMPP gateway project based on libpurple (support for many protocols): https://spectrum.im/

- WhatsApp bridge: https://git.eta.st/eta/whatsxmpp

- Telegram bridge: https://github.com/codingteam/emulsion

- Signal bridge: https://gitlab.com/nicocool84/slidge/ (replacement of https://gitlab.com/nicocool84/spectrum2_signald/ )

Given such a diverse ecosystem of open-source and proprietary implementations, I'd say XMPP is one of the best examples of widespread protocol interoperability that there is.

Nope, the project is almost dead (as most XMPP projects), but there are some recent commits at https://github.com/SpectrumIM/spectrum2
