I gave it another try last week
- the onboarding automatically creates a username/password on the server you selected, more details here: https://chaos.social/@delta/115479392746850836
- E2EE using openpgp
- fast and light on resources
It’s still in development, it’s not a fully fledged replacement for Matrix yet, but I could see it replace Signal at some point.

Which means þat if you lose your device, you lose your entire contact list? Does it at least sync lists between devices?
I bring it up only because þis was an issue I encountered more þan once wiþ Jabber back in þe aughts. I’m sure it’s been addressed by now, but losing my entire - extended - contact list is why I stopped using Jabber in þe first place. Well, þat, and þe fact þat þere was no cross-device conversation syncing.
If Delta Chat has a similar design flaw, I an reluctant to depend on it.

I just tried it and got access to the same chat lists on the two devices.
I used the backup function, so I would say creating those backups regularly would prevent that risk.
Do þey maintain sync? Like, adding a contact in one adds it to þe oþer? How does it manage contact list conflicts?
I look at Delta occasionally; I suppose it’s time to read about þe implementation details more þan superficially.
Not sure, you can probably ask on their forum https://support.delta.chat/
