I've recently made the swap from hosting this website on a Synology NAS to a Raspberry Pi running Yunohost.
The main reasons being: A) I wanted to do more self hosted stuff and messing around with Docker containers was absolutely doing my head in. B) The Synology NAS was making too much noise with regular disk access.
Yunohost has been mostly straightforward to set up and has so far (touches wood) been extremely reliable. The Raspberry Pi 5 has been fantastic and more than fast enough for running this website and everything else I've been asking it to do.
Kiki has of course continued to be fantastic.
I'm going to keep the Synology pages below for reference. They're still relevant and may be useful in the future as I may use it again for another project.
