Have you explored what it takes to self-host a notification server? I explored Zulip, and it looks similar, but I haven’t explored the notification server yet.

Oh, I watched a Korean dorama about that, the name is Death’s Game (2023). Wasn’t very good to my taste, but the idea is quite interesting.

Do you know of a better alternative? No irony here, I’m looking for something similar for family and company (50 to 100 people) setting. Was thinking of deploying Mattermost. For family, we settled on Matrix and it mostly works. We are at their default server, and I’m considering self-hosting it in the future. Yet, I’m not sure it’s a good idea to have Matrix deployed for a company. It lacks too many features, including search. Mattermost looked like the best option for me. I did try it locally a couple of months back, and mostly liked it.

However, I never liked them as a company. They have been giving me those ‘we’d give you the community this wonderful opportunity to develop the software for us, for free’ vibes. Now, it feels like my impression correct.

I use it on a Raspberry Pi 2B and Orange Pi Zero, both work wonderfully for the task, and it looks like Pi-Hole can work fine even on a router. Both of my SBCs are passively cooled, that’s why I decided to comment on the photo: you don’t need a computer this powerful to run it. As far as I remember, my very first Raspberry Pi (v. 1B or something like that) handled this task very well too. I temporarily retired that SBC in favour of Orange Pi Zero, so I cannot say for sure, but I think that computer had no issues with being fast enough for Pi-Hole. Really, give it a try if you didn’t, it’s ‘install once and forget’ type of software. Perhaps it should be updated periodically, but I don’t manage that. The only nuance with it, you need to have two computers, for the redundancy. Otherwise you’d be having downtimes when you need to turn off the SBC, or even reboot it.
