“Poor planning on your part does not constitute an emergency on my part.”

Codeberg isn’t an entirely new forge. It’s just a well-known gitea/forgejo instance. Sourcehut would probably be a better example.

From what I’ve read you need it for Bittorrent or at least the chance of failed downloads is higher without it.

Definitely worth it IMO. There’s a lot of parts involved in a Matrix setup and this playbook handles them all for you. Just make sure to have a look at the changelog whenever you update your installation. If there are any changes that require manual steps, it usually explains those steps quite well.

Security is only one part of it. If you host a password manager yourself then things like availability, backups, disaster recovery and monitoring also become your responsibility. I’m hosting my own vaultwarden but there is only a very limited amount of people I would suggest self hosting a password manager to, because I know they have the knowledge to do it and understand the risks.

Well, only if you host it in the cloud. Not if you host it at home, for example.

If I understand it correctly, the passwords are stored encrypted, but not the additional data, like website-URLs and app-names. This way the password manager only needs to temporarily decrypt a specific password when it’s needed for auto-fill. In regards to the passwords that’s probably a bit safer than keeping all the data and the passwords unencrypted in memory. But the cost is that all the other data is stored unencrypted.

I think Stash should cover most of your points, except for the page-less scroll: https://github.com/stashapp/stash The only other software I know for this is Porn Vault: https://gitlab.com/porn-vault/porn-vault

I’m currently looking for a software to host my images and I found this table quite helpful to compare features: https://meichthys.github.io/foss_photo_libraries/
