@tomgag #DeltaChat is the solution to all your problems, I have been admin of a #chatmail server for a while now, hosting +7k users in a cheap vps with 4gb of ram, only around 10GB of disk used, to be honest I sometimes even forget I have the server, it just works, requires zero maintainance, storage is auto-cleaned after 20days, profiles are auto-deleted after 90days after user stops using the account, profile creation is automatic, without spam problem because spammers can't write to people

@phanthomas if you use #DeltaChat or #ArcaneChat, I recommend you to use them with #chatmail accounts, which provide faster speed and prevent spammers/scammers from sending emails to your kids and other family members, only other family members will be able to get in contact with them via QR scan or invite link

YEAH! today, high noon in Berlin, Jonathan will present the upcoming #e2e #deltachat channels! well done! 🤘🎸

@mavnn I think you're right but you know what could be even better, a combo of your solution + something to associate links/QR with named tags

e.g: if I call this QR "Jose Perez" and share it with Jose Perez, then the app shoudl tell me the person who just opened a converation with me through that exact QR (or link) is using the QR with the tag "Jose Perez".

If I don't understand incorrectly you can have multiple different QRs to initiate chats. I don't know how though. But those QRs having a name tag could be interesting.

Am I making sense?

@adbenitez is this even feasible?

#DeltaChat

Another day another friend I convert to Delta and new UX issue discovered:

> people need to be reminded to put pics so you know which José you're talking with.

EDIT: At the same time if you share your QR or link in WhatsApp to just your contacts. In a status saying you're leaving WhatsApp.

#Deltachat

@fluidlogic @lunte161 @delta for information about #deltachat funding and organisation, also https://delta.chat/en/help#how-are-delta-chat-developments-funded gives some insights

Trying to get to the core of what's change on their Dovecot version. 🤔

I'm not keen on pre-built packages.

@xerz give a try to #DeltaChat it is the closest it exists today to a #decentralized #signal without phone numbers and with working nice multi-account and multi-device (without dependency on a main device!) and it even had polls before signal, and other in-chat mini-apps, #collaborative editors, #shopping lists, #games etc

@delta I think the killer features are simple:

1. Actually decentralised. Not tomorrow, not theorical, not a work-in-progress. Decentralised: NOW.

2. WebXDC apps taking advantage of that decentralisation are going to be one of its biggest pulls. PixelSocial can entirely overtake local neighbourhood/family FB groups for example once is a bit more feature-complete.

3. Everything's encrypted without annoying you like Matrix

4. UI feels famiiliar like old pre-FB-purchase Whatsapp. Smaller learning curves or no curves at alll, are awesome.

#Deltachat

@profoundlynerdy Ok, alright. Was asking because there are real flamewars going on about which one is the right one to use.
So, there's #Matrix and all it's apps.
Simpler, and more #KISS to me, is #XMPP:
Install #Prosody using #YunoHost
Use #ConversationsIM on #Android
#Monal on #iOS and you're good to go.

Little bit more oldschool to me is #DeltaChat: Just use the mail protocol for chatting.

@fuat2mb @delta_chat it's a neat idea to postpone server choice until later, and onboard with some default.

#deltachat apps are currently learning to use multiple addresses at once ("multi-transport"), along with cryptographic hardening against evil server operators. The goal is to provide multi-server onboarding by default, and to automate server migrations (although for a while there will be an advanced settings interface where it's manually managed). You'd be onboarding "to the network" :)

Well, maybe we need to be more clear what we are trying to do: #deltachat apps are a cross-platform private messenger suite, that aims to provide a consistent UX/UI for users with lots of experience using WhatsApp and Signal.

Telegram has good fast UX but is hardly a private messenger (it has a central cleartext database of everyone and everything).

Matrix and XMPP are well-esteemed fellows in federated messaging, but so far didn't grow a WA/Signal-level cross-platform messaging UX.

YMMV

@LisaBanana some point for #DeltaChat over #signal:

it has collaborative in-chat mini-apps, this is a huge game changer, suddenly your family can organize the house's shopping list and anyone add/remove items to buy, some people use it for this reason alone

the children of the family can use it without sim, the elderly without scammers contacting them by phone number

easy onboarding, no phone numbers, no SMS codes, no CAPTCHA solving!

Capture d'écran 3.5 Billion Accounts: Complete WhatsApp Directory Retrieved and Evaluated Vienna researchers retrieved all WhatsApp numbers. The 3.5 billion profiles represent the largest data leak in history—and it's worse than you might think. The entire member directory of WhatsApp was available online unprotected for retrieval. Austrian researchers were therefore able to download all phone numbers and other profile data—including public keys—without encountering any obstacles. They found more than 3.5 billion accounts. Measured by the number of people affected, this is likely the largest data leak of all time. Part of the research group has already dealt with WhatsApp several times and, for example, determined what WhatsApp reveals despite encryption and discovered how an attacker can downgrade WhatsApp encryption. Nevertheless, WhatsApp operator Meta Platforms turned a deaf ear to the new research findings for a year.

@midge @hdrc @Tutanota #DeltaChat all the way, no phone numbers, no personal data AT ALL required for registration, decentralized, in-chat mini-apps, it even had polls before #signal and in a much more flexible way, together with collaborative editor, calendar, shopping lists, split-bills, mini-games, all #e2ee without depending on any server

Mental note of an idea before I forget and never tell anyone: @thunderbird should adopt and dig in deep on being the best in class mobile and desktop client for #DeltaChat in addition to being an email and RSS reader. Compete on simplicity and features against closed, commercial Messangers, not just corporate email. Thank you for your attention to this matter.

Probando Arcanechat (Movil) y Deltachat (PC) y tengo decir que me esta gustando una estética muy de Telegram sin toda la morralla que se le esta metiendo, lo único que me falta convencer a gente que se pase, eso ya es más jodido.

#ArcaneChat #DeltaChat #ChatMail

@phl maybe ask @adbenitez to get the full marketing-blurb :) but as far as we understood: there are more services integrated like a set of chat bots and UX/UI tweaks/improvements/mods that may or may not make their way to the mainline #deltachat apps sometime.

So what's "extra" about #ArcaneChat in comparison to #DeltaChat? That's kinda the only thing I couldn't readily see on the website.

@largo some user-visible differences to Signal:

- onboarding with #deltachat is among the fastest in the industry

- easy to create multiple chat profiles

- multi-device setup and export/import are easy, also between different platforms

- no phone number needed so eg children can participate without forcing a SIM card on them, and without making them discoverable anywhere

- shopping lists, travel checklists, and games like Wonster (a wordle-clone) or Tetris are available for group fun

Signal just released a "poll" feature with great fanfare, while all #deltachat apps already integrated a full suite of chat-shared apps, checklists, polls, shopping lists, calendar, editor + tons of games.

Better, anyone can create new apps, eg as github/codeberg forks from existing apps, and post it to their chats for instant deployment. No need to ask for permission, register an account, and no hosting or DNS: actually "server-less" and fully end-to-end encrypted :)

Any data that is collected on servers will eventually leak or be abused otherwise.

By design, no one can enumerate #deltachat profiles which are private and not published on any server. Conversely, #chatmail relays do not see or collect private data or metadata.

But wait, there is more :)

We are currently evolving end-to-end security protocols and UX to **survive an attacker fully taking over a server**. The attacker shall not even be able to message users, let alone impersonate anyone.

I'm positively convinced that #deltachat is developed by some kind of magic.

I wonder what would happen if their developers took on the hard problem of cheating in online games like CounterStrike or ApexLegends. 🤔

@maikel it's unlikely #deltachat contributors go for tying identities to insecure and tightly state-controlled phone-numbers. It would be tons of efforts and would derange us from our goal of providing private messaging tooling, easily replicable, useable and extendable at federated scale. However, easing getting-in-contact UX flows are a high priority and under continuous contributor discussions.

I might be deleting my Matrix account, I find it utterly useless. Let alone the continous ask for confirming encryption is incredibly poor UX.

@delta sounds in paper like the ideal federated service and the interface of the Android app so far looks like old-whatsapp which makes it easy.

But frictionless account discovery is still the issue. How do you talk to your contacts using DeltaChat when you can't find who on your concact list (eg.: by phone number) is on DeltaChat?

Signal and Telegram do discovery better in that they allow you to choose if you want to be found by phone or a handle.

#deltachat #matrix #UX

We were surprised to hear today that Forbes.ru (a subsidiary of the global Forbes brand it seems) recently published an article quoting an expert recommending to use #deltachat on the backdrop of restrictions of Signal, Whatsapp, Telegram, Discord and Viber in Russian networks.

https://www.forbes.ru/tekhnologii/548966-ne-gasite-vasi-ekrany-cem-zamenit-telegram-i-whatsapp

@rysiek @dos @mebbie I'm a non-developer daily driving #postmarketOS on a #Librem5. Eveything important works including VoLTE calls, SMS, Wi-Fi, 4G, web browsing, web apps, #e2ee messaging and calls on #Signal, Matrix, XMPP and #DeltaChat, GPS, camera, etc.

#deltachat is a private messaging app. It'd be easy enough to offer various public groups to boost onboarding, and let everyone play. But one would land in a large group that isn't very private, with lots of needs for moderation tooling, troll handling and other social-media issues. Not our current cup of tea.

We are grateful for the many folks here onboarding their families, projects or friends, founding special-interest chats, setting up #chatmail relays etc. This is wonderful, cheers!

@ferrex you are right. #Olvid is pretty well done regarding UX for boarding and getting in contact, largely similar to how #deltachat does onboarding, with interesting differences. Something to learn from (we think in bot directions). Thanks for pointing this out to us!
Do you happen to know any olvid people in the fediverse? It's not an open source project and work with a central transport server, no federation etc, but still interesting to engage with from a UX standpoint.

Também queria provar um outro cliente de Delta Chat, ArcaneChat, mas não sei como fazer tendo as duas apps no telemóvel... O sistema vai com códigos QR e... 🤷🤷

Alguém sabe? Obrigado

#Arcanechat #DeltaChat

@adbenitez if these #Deltachat channels can be shared and joined by QR code, I say they have a chance to succeed where #RSS feeds failed. The normies of the world are loathe to copy magical URLS and paste them manually into some other app.

Which #OpenSource #decentralized, group #chat which supports E2E (end-to-end) #encryption is best? #infosec
#fediverse #Matrix #XMPP #Deltachat #privacy #security #OMEMO

@adbenitez having said this, I know more than one person who administer larger group chats in #WhatsApp (100's of members), and an important feature for them is that the administrator of the group can set the group "read-only" for most members. This is to stop people from posting whatever they want. This rigidly locks the group topic to what the few privileged posters post. This very much makes it like a "one-way" mailing list, where you either subscribe, or you don't (but you don't really contribute postings back in an open discussion). This is to silence unruly upstarts who might actually compete with, or run across the grain of the chat room's more narrow, focused, stated intent. These more strongly hierarchical-minded types would not like #Deltachat (nor #RSS, sadly, which is what I would prefer to recommend to them).

I'm trying to convince these "glorified mailing list" types to use #Signal (has group features similar to WhatsApp), but the progress is very slow.

@d1 that read-only groups are a poor implementation of channels (like #telegram channels), which are coming soon to #DeltaChat

Many experts caught up in the past crypto/decentralization discourse fail to recognize one key innovation area of #deltachat and #chatmail efforts:

A user interface (UI) and experience (UX) that mimicks and closely resembles Whatsapp and Telegram ... who both have a central cleartext database of identities, social graphs and, in the case of Telegram, also messages and media, of billions of users!

We prefer to ground every discussion in UX/UI terms and measure security by outcomes for users.

@lexinova @upofadown FWIW there are some non-electron clients https://chatmail.at/clients and an upcoming post about an experimental Tauri one. The current #deltachat desktop electron-based client tries to both size-bloat/ram wise do better, and also e.g. bars the frontend rendering process from doing any Internet connections which are purely done via the Rust core library, for all #chatmail clients.

@fabrice @freddy we hear you but it's the truth: by onboarding to #deltachat today you are diving into an experimental testrun of "the future of email" , also known as #chatmail https://chatmail.at

Finally we, as app distributors, want to fully disentangle from any "default" server. Testrun will become history :)

Alt...

homepage of https://testrun.org with the subtitle "experimenting with the future of Email"

I agree. @delta did a great job with this UX. Built upon the email protocol (with e2ee encryption added) they are just as decentralized and federated as email, or for that matter Mastodon. They are a great deal MORE decentralized than Signal or say, BlueSky now. But their UX did an excellent job "hiding" the complexity. Others decentralized/federated platforms should learn from this example! #deltachat
https://chaos.social/@delta/115479392746850836

@crazy_pony

1) there are bridges ("matterdelta") which provide interop with Matrix, XMPP, Telegrram, ssh and anything that Matterbridge provides. It doesn't preserve end-to-end encryption and so bridging bot choice is tricky.

2) There are growing efforts around 3rd party #chatmail clients https://chatmail.at/clients. Interoperability is "free" between all chatmail clients (#deltachat being the prominent one). Unlike #Signal we welcome third parties to the party :)

@delta I agree, #Deltachat is awesome for superfast account creation, then sharing the account by QR code. No password set or stored, no phone number or email given, no password manager grumbled about necessitating

We hereby challenge _all_ other messaging apps, FOSS or not, to provide a more convenient private onboarding experience than #deltachat

1. Install app
2. "Create new profile"
3. Enter nick name, tap "Agree and continue"
4. Tap "+" and "new contact" and provide/scan qr code/link

Voila! A secure private chat, familiar to those coming from Whatsapp or Telegram (without "AI", with #a11y).

Note: chat identities are private and can not be queried or discovered. Servers keep no track or metadata

for things like this I completely avoid upfront any platform that depends on phone numbers and I prefer to use #DeltaChat

Per un cost molt baix, menys de 5€, pots tenir un servidor de #DeltaChat (els anomenen relays) capaç de gestionar tranquil·lament uns quants milers de perfils.

"A Debian 12 server with reachable SMTP/SUBMISSIONS/IMAPS/HTTPS ports. IPv6 is encouraged if available. Chatmail relay servers only require 1GB RAM, one CPU, and perhaps 10GB storage for a few thousand active chatmail addresses."

https://github.com/chatmail/relay

Hey @delta! Reading this https://delta.chat/en/2025-05-22-browser-edition got me thinking. I live in Firefox but miss Chrome’s one-click “Install PWA as app”. What about a Tauri-based helper + a Firefox extension that wraps a PWA into a desktop app in one step? Hosting stays light: the PWA is cached; relays/self-hosted instances can serve the client. Keeps control with admins. Interested? 👍🏻

Great post from @Jdm2 about his getting away from WhatsApp and looking into #deltachat

https://write.as/jdm2/deltachat-y-arcanechat-son-las-definitivas-alternativas-a-whatsapp

We also just reposted his invitation to a Puerto Rico group, because we think the way this group is instigated is exactly right: ask for people to drop into a DM, or like with the borken.social Fediverse instance: show an invite link only for authenticated users 🎯

Non-public invites maintain some privacy and sense of joiners and brings e2ee messaging to instance communities.

Ja sé que tots sou molt racionals, però en el #DeltaChat, quan entres dins dels grups, en el fons de pantalla, a part de clar/obscur podria existir també la opció d'insertar una imatge des de la teva galeria, per canviar el fons?

Countering toxicity and fake takes is not just a technical question (moderation, admins etc) but one of social curation both collectively and privately: which people and groups do you/we trust for what. No tool can automate that.

#deltachat is for private e2ee messaging and mutually curated group chats, and not random social media propelled onboarding. We are with #Signal here and not with #simplex and #matrix who offer public anonymous discovery of large chat groups with lots of unknown folks.

@surfhosting thanks for trying and telling about your experiences!

We generally recommend to use #deltachat for private chatting and your "300 people group" does not sound quite like that. Delta Chat is not geared and not well suited for groups of hundreds of people, today. Are the issues you noted related to such larger groups? If not, would you mind sharing a few, maybe on the https://support.delta.chat forum?

Today, we were nicely surprised by @gianmarcogg03 with a new comprehensive (italian) #deltachat introduction video, going through initial setup, groups and chatting, second device setup, #webxdc apps, bots, calls and playing Quake -- all the nice things you can do these days :)

https://mastodon.uno/@gianmarcogg03/115462294953394774

containing peertube, odysee and youtube links (latter provides English subtitles)

Fun fact: devs noticed some tiny but embarrassing glitches in the UI which are now getting fixed as we speak :)

@vermaden @delta you can make #DeltaChat desktop work on #FreeBSD

you can build it yourself https://support.delta.chat/t/delta-chat-on-freebsd/2948

Or wait a bit, because @feld is working on making a real package for it.

@delta

...but there is one thing that #Deltachat does not provide while it works perfectly fine with #Signal ... the desktop client that works on #FreeBSD and is available in #FreeBSD pkg(8) packages.

The 'web' approach (such as https://web.whatsapp.com for WhatsApp) would also satisfy my needs - I can use a client in the browser - but if there is no 'native' client and no browser client option for #FreeBSD - that means total NO-GO for me.

I find it bold stating that #DeltaChat doesn’t need a hyperscaler like #Signal does when it is based on… email servers. Where there is no audio/video calling. Where every sender and recipient server knows who is communicating with whom. Where you need to trust every decentralized server to not keep that information. Maybe be less smug if you can’t provide metadata protection. 🙄 @delta https://chaos.social/@delta/115454041149791990

Signal's president claimed it takes billions to replicate the availability and reliability of "hyperscalers" (AWS/Google/Microsoft/Cloudfare) that Signal uses.

#chatmail and #deltachat are about disproving this claim by

1) making relays super cheap (DONE)

2) enabling chat profiles to use multiple relays redundantly (WIP)

3) distributing relay knowledge among chatters (TBD).

Fat servers, corporate overlords and billionaires: not needed and better to not exist for a convivial e2ee future :)

Delta Chat és una aplicació de #MissatgeriaInstantània que respecta la #privacitat al màxim perquè xifra els missatges de persona a persona (també en els grups), és programari lliure i els seus servidors son federats.

@liaizon I feel like #DeltaChat is exactly that: a lesson in almost every aspect of what is possible and what should be done.

@machocam @liaizon That is indeed an interesting question, and as it seems to happen more and more #DeltaChat seems to have a surprise ready: Due to the battle proven email-server software we have today, combined with the fact to set up the infrastructure to basically only facilitate messages slipping through the cost is – compared to Signal – a fraction. I'm no expert and have no experience, but what I hear sounds impressive.

Buenos dias a todes desde #deltachat usando su #mastodonBridge

@ivangj Jo, quería probar a instalar #DeltaChat en mi BlackBerry, pero veo que el archivo apk requiere Android 5 como mínimo y mi BB solo es compatible con apps hasta Android 4. No sé si habría otra manera de instalarla (sí puedo usar XMPP con una app antigua, por ejemplo) @delta

Was just looking at #DeltaChat but frankly, who would I use it with? I’m sure it is wonderful but I have nothing to say.

@delta @ati1 Re: #DeltaChat on #Librem5. I just tested the experimental direct 1:1 calls and it worked great : ) The call ring sounded loud and clear on my Librem 5!

@delta
It ist great and I love It! 📞 🤩

#deltachat #call

We are aware of roskomnadzor just having ramped up their blocking efforts in #russia against #deltachat 's default onboarding chatmail relay. Signal, Whatsapp are degraded/blocked for a longer time already.

1) Delta Chat has first class shadow-socks proxy support (try ss:// links you can find ... Delta has management-proxy UX)

2) many other chatmail relays work fine and inter-chatmail/email server traffic continues unimpeded

3) if you can help with analyzing please drop into our DMs.

La gente de #DeltaChat vuelven a impresionar 🤯 ahora con llamadas P2P (**en beta**)... Donde los servidores no necesitan hacer NADA especial, ni siquiera actualizarse. Todo sigue funcionando bajo estándares de #email. 😍

Hay algo mágico en una aplicación que consigue ser tan independiente incluso de su propia infraestructura. 🪄

Brillante trabajo, @delta, mis felicitaciones. 🚀

Believe it or not: #deltachat is growing audio/video calls starting with the currently rolling 2.22 releases ... A few people already had two hour long stable calls :)

Calls are an experimental option while we continue to work on reliability, UX/UI revisions, and configuration of TURN servers on #chatmail relays and in clients.

We want calls to reliably work across all major platforms, networks and phones, including #UbuntuTouch

#DeltaChat

I've been on the hunt for some accessible, easily self-hosted (on prem or datacenter) chat solution for a while now, and I've been looking very closely at deltachat/chatmail.

Not gonna lie, the fact that just uses mature SMTP facilities for transport is making me weirdly aroused.

If anyone has experience running their own chatmail server or just using deltachat in general, I'd be glad to hear from you.

#DeltaChat #ChatMail #SelfHosted #HomeLab

@delta @fedicat @eXOfasia there's one in #Canada, which is nice. #ElbowsUp #DeltaChat

Good news! It's getting harder to keep track of new #chatmail relays :)

Recently several public relays were added to the https://chatmail.at/relays list, in Warsaw, Helsinki, Romania and Barcelona.🧡

If you have #deltachat installed on mobile, you can go to any chatmail relay website in the list and click on a link there to create a chat profile.

It's wonderful to hear about collectives setting up chat infrastructure like the recent https://xat.fedi.cat from @fedicat and @eXOfasia

@kuketzblog

#DeltaChat needs update:

DC has 500K+ downloads in google play

e2ee encryption should be "yes", default onboarding servers don't even allow to send/receive unencrypted nor can people disable encryption, while #Conversations has "yes" and the xmpp servers don't enforce encryption, groups are often unencrypted and it is easy to disable encryption

max. number of participants per group is 1000 (depending on server)

Werft mal einen Blick auf die Messenger-Matrix. Trotz aller Bemühungen kann es sein, dass nicht alle Informationen zu den Messengern aktuell sind. In diesem Fall bitte ich um Rückmeldung, damit ich die Matrix anpassen kann. ❤️ 👇

Not taking Venture Capital money means:

- No pressure to maximize monetization of usage (for every million of VC funding you need to find ~100+ Million in value later).

- No prioritization of growing fast with PR campaigns that promise the moon and stumble on the ground

- No billionaire who ultimately profits

Instead, we seek public funding and private contributions for #chatmail #deltachat and #webxdc developments.

Thanks to everyone who is helping and already test-driving things :)

home page picture of https://testrun.org text title "Testrun.org" with the sub title "experimenting with the future of Email" the picture is a collage and shows the head of a dinosaur with an open mouth and many teeth trying to swallow a Zeppelin that seems to be flying directly into the mouth. Next to the dinosaur head is a classic "@" email symbol. the middle part is blue, and has overlay graphics of a moon-like planet and some old computers in the back the bottom part contains a picture of a sysadmin ca. 1975 in front of computer screens that show green letters on a black screen. There also are separately three cryptic letter chains that seem to translate to "Communications", "Command" and "Sigma". Another "@" sign is left of the computer screens.

@cos hi, for your information there is a #DeltaChat #matterbridge plugin, that means you can bridge Delta Chat rooms to #Matrix, #Telegram, #XMPP, #IRC, etc

https://github.com/deltachat-bot/matterdelta

there is also other alternative bridges, ex. search for Telegram here:

@redbr1ck Delta on itsessään ihan kiinnostava, mutta siitä puuttuu Matrixin yksi oleellinen ominaisuus eli sillat. Deltalla voi jutella Deltakäyttäjien kanssa, mutta Matrixilla pääsee olemassaoleville kanaville eri viestimissä. Ainakin itsellä tuo on ihan ratkaiseva ominaisuus kun suurin osa omista yhteisöistä pyörii matrixin lisäksi irkissä, telegramissa tai discordissa.

Mutta Delta on kuitenkin "hyvien puolella" ja toivotaan että yhteisöt valitsee sen esim discordin tai muun suljetun/keskitetyn vaihtoehdon sijaan.

Ps. Matrixin ja Delta Chatin välille on rakennettu siltaa, mutta näyttää että homma on jäänyt kesken. Ehkä se joskus saadaan kasaan.
