git-sync looks like it does at you're looking for.

Oh, nice. Saving the link's content is exactly the feature I've been looking for.

As someone who was also recently looking for a multi device alternative for mihon/tachiyomi, I highly recommend Suwayomi. It's even somewhat compatible with Mihon. It can use the same extension repos and you can restore Mihon backups in Suwayomi, which makes the migration pretty smooth.

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.

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 think it's actually pretty clean. Thanks to the references on the person table all related entries in the database like posts, comments, etc. also get deleted if there are any. It's better than banning all those fake users and thereby spamming the modlog of all instances that federate with you 😅
