For photos, I have been using Immich, and have been very impressed. It has pretty much all the features I want (automatic backup, chronological timeline, mobile/web app, face tagging, semantic search, albums, sharing, etc). It’s a server you self-host though, so setting it up might be a pain if you’ve never done something like that before.

You have any sources for that? Never heard of this before; sounds interesting.

And a drop in costs too since their system has to support less users.

What is this optimized cmatrix you speak of? The normal one slows my desktop to a crawl when it runs.
