It’s covered by paying users. I’m one and happy to have my subscription cover Anyone who wants a free, private email address.

Just use a sonatype nexus 3 image and proxy docker hub, etc. Then you pull images through it.

You use calibre web. Then on the Kobo you connect it to your computer, backup 1-2 files, then change the store link to your domain name for your calibre web. Simple json file iirc.

Works well but doesn’t sync progress I don’t think.

It is BUT you are limited to their test servers for mobile notifications and they honestly suck. It’s a coin flip whether you get them. And if you want better you have to set up your own container system like them with firebase and Apple Dev ids.

I like it still but for a Greenfield project I’d probably try matrix 2.0 on synapse with element x as the mobile app.

If you don’t need notifications I’ve actually found just adding it to Firefox as a pwa works well for me. Mobile interface is surprisingly good.

Except a lot of people won’t take just money.

It’s psychological but it’s true.

I’d like to see some documentation that says passkeys were intended to never be synced across anything.

Everything I have ever read is that it’s basically asymmetric cryptography like ssh keys. You have a private one, generate the public and give it to the site. It stops reuse of passwords and site breaches become useless as the public key is useless for attacking an account on another site, etc. (well, besides whatever data was lost in the breach which is outside the scope.)

I see no reason to limit someone having the private key on their phone, their desktop, etc. Having to generate yet another passkey for every device is inefficient and would decrease adoption of this.
