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.
I think you’re looking for something like this: https://github.com/meeb/bandcampsync
Username on github seems to be the same as on Docker Hub: https://github.com/sciactive/nephele
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.
