Hi! I've done some research on self hosting Matrix for Matrix Bridges on a Raspberry Pi 5. Some people have said online that Matrix will be too beefy for an RPI due to large federated chatrooms and information. However, would it still be worthwhile installing just for my own bridges for social media, and maybe as a secure way for friends to interact?
Not that the raspberry pi is particularly low end anymore, but if you do want to run matrix on low end hardware you may want to avoid synapse as it is very resource heavy.
There are a couple implementations that support bridges here
Uhm, this is not very good advise, as the bridges especially often do not work well with non-Synapse homeserver implementations. And especially Conduit also has a very different way to setup appservices, so it becomes much harder to configure the bridges correctly.
It might depend on the particular bridges, but all mautrix- bridges work great for me with conduit. In a way adding bridges to conduit is easier since it's all done through the admin room on conduit.
Matrix needs fast storage, and a lot of it, even if you only use it for bridges. A RPi5 with a good amount of NVMe storage will probably work, but if you only want to use it for bridges I would rather recommend to set up an XMPP server with Slidge which gives you better clients and can run on a RPi4 easily.
I'm unsure why he mentioned a good amount, as I am across several large spaces on the matrix using Synapse and have accumulated approximately 30GB of data in >1 year. I must clarify that I am the sole user of my instance.
Not sure if that's true. I've ran a Synapse Matrix server on a SBC before and it worked. Just for a few users though. I don't know if it breaks if you have like 300 people using that...
You could use conduit.rs as a server. That runs on a few tens of megabytes of RAM. Not a whopping gigabyte. At least that's what I'm using now. It's still missing a few features, though.
Funnily enough I considered that, but I literally couldn't find installation instructions anywhere on their site. The documentation has stuff for configuring a running instance but nothing for actually installing it, lmao
If you end up going with conduit, I would instead use conduwuit. More development effort and better docs IMO. I think maybe even one of the main devs from conduit moved over to conduwuit? But not 100% sure
Yeah. Their documentation is a bit "lacking" so to say... it's practically nonexistent.
They follow the usual procedure, though. So if you already set up 10 webservices on your server, you will know what to do. They documented a few special things like how to hook the appservices. But also that took me some trial and error.
I believe it's more for developers at this point. And people with a lot of expertise. That may change. And it already works well for the basic stuff. But i'm not sure if I'd recommend it unless it's a special case like this.
If it was the pi 4, I would agree, but the Pi 5 would probably handle less than 20 people. I have a 4 that uses Yunohost that covers a LOT of services. I played around with matrix but it required too much out of the system. But that's with a lot of other services running. Give it a shot and let the rest of us know.
BTW I had a lemmy/irc/bookwyrm/mastodon all running on the pi4 without any real issues. Mastodon is probably the beefiest/slowest app, and its been getting better as time goes on. So a PI can definitely work with fediverse apps.
From my limited Raspberry PI experience I believe their single core performance isn't great and synapse at least is single threaded. You'd have to use workers to utilize the other cores. If you have multiple pi devices you could also utilize workers on different pis and hosting postgres on one. Using only one, it would likely be quite slow like others noted.
