Regarding different outputs for the same seed: have You changed seed source to CPU in A1111? The noise You get that way is consistent across different hardware vendors and different from the GPU-sourced one.
I have used A1111 just now to check and got very simmilar results to ComfyUI that way.
I use beets in my setup and I am pleased with the results, keeps my library nice and clean. It is very capable by default and you can extend it even further with plugins. It will do fine importing well sorted albums and if you have a mess there’s also tag by filename and acoustic fingerprinting. You can use multiple metadata providers and adjust their weights for preference. It’s well documented and multiplatform (it can also be deployed as a container on a NAS system and manage of your imports). The biggest drawback is that you have to read a few pages of the docs before running it or do some dry runs.
My bad, I should have worded that better, thank you for making it clear, that’s exactly what I had in mind.
General advice would be to look boring and hide your IP as much as you are able (get a domain). As long as you’re not looking juicy you won’t attract skilled attention. It’s like locking a bike, most bad actors will just pass by looking around for one without a lock or a real fancy one worth their resources.
You can utilize Cloudflare’s free offerings, starting with simple stuff. Their DNS Proxy is essentialy a single-click but will help substantially. You can build on top of that with simple WAF rules, such as droping connection attempts from IPs originating from countries notorious for “poking around”. You can also reverse that rule and whitlelist only your country.
Keep your firewall tight, don’t expose other ports, put your services behind a reverse proxy and redirect everything to HTTPS. Start simple, constantly improve, learn more advanced methods/concepts.
I usually recommend this one. There’s a section for NPM you’ll find useful.
I used to run Authelia with NPM. It supports TOTP as second factor.
I know of a project that may match your description: https://github.com/azukaar/Cosmos-Server
I remember seeing it some time ago in a self-hosted community, but don’t remember on which platform.
Pretty much vanilla, only --xformers --medvram arguments and CPU seed. In that case, someone with more A1111 experience should weigh in, mine is limited, I mainly use comfy nowadays and probably am not up-to-date with development.
