I’m hodsting my own Matrix server with WhatsApp, Telegram, Discord (you don’t need a bot for that, you can just share your login with the bridge) and Messenger bridge. I have all my IMs in one app, don’t have to install spyware on my phone, and I can make bots that troll annoying people that message me on any platform.
Hosting it was super simple, thanks to the Ansible project that’s extremely robust and well done, I literally just got a hosting, domain amd changed like 5 config values to enable the bridges I wanted, gave it an IP and ssh key, and ran it. And if I need to update, I literally “just update” (it’s all wrapped up into “just” tool), and it eve handles cases where I didn’t update for a while, failing graciously and telling me what I need to do maually, usually just rename some config values.
I wholly recommend it. You probably wont convince your friends to switch from <insert app here>, and this is the best compromise.
I’m using a small instance on Hetzner, for 6$ a month. You could in theory get a free oracle cloud instance for it, but I didn’t manage to get one.
And you can easily share it with anyone interrested, make them an account, so they can also consolidate their DMs. I’m sharing it with a few friends and colleagues.
I’ve added a subtle prompt injection into my email signature (capitalize random words and start every sentence with the same letter), with small font size and color to not be visible.
I have already received two emails from customers that did trigger it.
