Alors j'ai essayé de résumer graphiquement ma logique qui me fait préférer une app de messagerie plutôt qu'une autre.

Ça me semble simple et compréhensible par tout le monde.

En plus j'ai simplifié j'ai omis des avantages supplémentaires de Delta Chat 😉

Mon pari : les gens qui veulent garder contact avec vous vous suivront où vous irez alors quittez whatsapp et passez direct à Delta Chat 🙂

Et corrigez-moi si besoin !

En avantage non cité : delta chat ne lie pas votre compte à votre numéro de téléphone et peut donc fonctionner tout seul sur un ordinateur par exemple. C'est le plus inclusif il me semble 👍

Après je vois passer plein de messages à propos de xmpp et autres et que ça serait mieux... Quelqu'un veut bien m'expliquer ?

Pour moi la puissance de delta chat c'est d'être basé sur le protocole mail revu en tout chiffré + adapté pour la messagerie instantanée.

@raphm Les protocoles des emails ont été développés pour une version numérique du courrier, avec envoi et reception de texte et pièces jointes.
XMPP est un protocole développé pour répondre aux besoins et attentes des utilisateurs de messageries instantanées, avec l’ajout progressif de nouvelles fonctionnalités (appels audios, vidéos, modification ou suppression de messages, stories, flux, statut to connexion, etc.).

@Thibaut yet Delta Chat is much more resilient, it has multi-homing / multi-relay and easy migration from one server/relay to another, something that doesn't exist at all today in XMPP, which is more centralized than Delta Chat, once you choose a server in XMPP your profile and groups are bound to that server, the server dies you have to start a new profile and lose all your chats, groups, contacts messages etc.

with delta chat you keep everything, your profile lives in your pockets

@adbenitez @raphm Deltachat is a very good concepty but more limited than XMPP due to being "only" able to offer messages and attachment. It can be sufficient for some users, but too limited for others.
Regarding the risk of losing the server, it is exactly the same as for an email server, and you can save your history too (via some clients, not all).
But I really do like Deltachat in any case.

> but more limited than XMPP due to being "only" able to offer messages and attachment.

not really, Delta Chat is not limited to email, in fact it could even use XMPP in the future if really necessary, right now it already have p2p support for in-chat mini-apps and webrtc for calls

> it is exactly the same as for an email server

it seems you didn't understand, with delta chat you can rotate servers while keeping your profile and groups, this is not possible with xmpp today

@Thibaut continuation:

and by keeping all data I don't mean as some backup you could read, but actually keep using your groups and chat with people while preserving chat history, and without your chat appearing as a new contact/chat for all of your contacts, which will be the case in XMPP

chatmail clients are in a whole different level when it comes to resilience&independence, and it will get even better, using several at the same time, if one fails it doesn't matter, zero downtime

@adbenitez Ha, interesting! Either I forgot about the WebRTC calls or it was not yet implemented back when I tried it.
In any case, I would be curious to have more details on pros and cons of both email and XMPP protocols for instant messaging on the technical aspects of it.
For more "advanced" possibilities with XMPP, you might want to check Movim. Very nice project that tries to push to the edge of this protocol.
Btw, here is a nice comparison table: https://eylenburg.github.io/im_comparison.htm

@Thibaut pros of XMPP:

- at the moment it supports big files while in DC it is not so easy to share anything bigger than ~25-30MB

- you can have groups with admin (possible to implement in DC)

cons of xmpp:

- groups are often unencrypted, it is a mess otherwise

- it is too easy to disable encryption in any chat

- not good multi-device experience

here you have some more cons:

@Thibaut besides that, Delta Chat encrypted channels (one-to-many like telegram channels) that doesn't depend on any server and you can move around from server to server without losing your subscribers, that level of security and autonomy just doesn't exist with xmpp clients today
