Anyone here with practical experiences compared to the slightly more expensive M3 Pro? (except it's not supported by Rockbox)

Tried the same some time ago. While setup is fun, maintenance etc. is mostly underestimated. Following Murphy's law, things mostly break in uncomfortable times (deadlines, etc.).

My (current) strategy: Do without the "last functionality" and stick with boring, local software/approaches. Not everything needs to be synced to / accessible from any device -- at least for me... One well backed-up machine, a few online services (e-mail, github for collaboration, ...) and long-proven applications like Photos.app. Something close to the situation 15 yrs before?

Why did they not consider Pimcore? Other parts of their platform seem to be using Symfony too...

Could be either used as "full CMS" or as data source for a downstream static site generator...

... I felt quite confirmed while reading this. After months of thoughts and plans, I finally invested some hours to install Gitea on my Synology NAS and migrating all GitLab projects there. Combined with Synology Drive + Wireguard running on an EdgeRouter by Ubiquiti, this feels somehow good. Of course, just for my personal files that don't require collaboration with others ...
