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 :)

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

Ho fatto un tutorial su @delta@chaos.social, un sistema di messaggistica istantanea libero e privato basato sulle e-mail, ma con un'esperienza utente molto simile a WhatsApp, se non migliore. :peertube: PeerTube: https://videos.gianmarco.

...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 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 chaos.social/@delta/1154540411…

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 :)

Base tech resilience comes from tools that can be used offline. #deltachat apps are offline-first in that you can create chats, send messages, look at messages/media and trigger establishung contact via qr code scans. And you can use #webxdc apps (with checklist, calendars, editors, shopping lists etc) because they not only don't require Internet but are barred from accessing it, providing privacy that doesn't require #gdpr or consent or login.

#deltachat #UbuntuTouch #deltatouch

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.

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

Feedback and debugging happens at support.delta.chat/t/help-test…

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

Recently several public relays were added to the 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 xat.fedi.cat from @fedicat and @eXOfasia

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.

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 :)

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.

There is no single central #Signal server. Signal uses #AWS cloud, plus Google Cloud, Microsoft Cloud and Cloudflare, all under US legislation. If any of these clouds goes down or becomes otherwise problematic, chatting degrades or fails.

With #deltachat you can choose #chatmail relays ( chatmail.at/relays ) which distributes the risk across a wider network. We are currently working on the multi-transport feature to finally remove any central point of chat failure chaos.social/@delta/1153621448…

With @signalapp having a problem because AWS us-east-1 is having trouble, I'm looking at installing @delta as a side-channel for situations like this ... does anyone know if it does video?

I know it's a chat function, and I'm not asking for miracles. It's a genuine question about capabilities.

I see there are web apps, and capabilities to integrate things, so I'm wondering what's available in the base install.

My investigations begin ...

Dear @Tutanota would it be technically possible for you accept the setting for #deltachat ?

Thanks in advance.

While #chatcontrol poses an existential threat to the Freiburg merlinux GmbH and distributing #deltachat apps from within the EU to all stores worldwide, it would resist any chatcontrol legislation up to the German constitutional and EuGH courts.

If the EU based company would need to fold in a few years, there would likely be forks distributed outside the EU that will *seamlessly* continue to function. Our architecture and FOSS licensing makes sure of it. See also chaos.social/@delta/1134177407…

We consider our efforts aligned: #deltachat #chatmail and #webxdc implement "right to exit" on all levels of our decentralized messaging project.

- deploy your own servers permission free and interoperable with all e-mail servers ("federation mast")
- all apps and libraries and server components are 100% Foss
- interactive chat-shared web-apps can be used in other messengers

Woah! Only now did we discover a great blog post from @wq who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay runtimeterror.dev/self-hosted-…

It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.

#deltachat is being used in virtually all world regions where one or more other messengers fail to work. We recently released a major milestone (V2 security hardening releases) that prepared the ground for chat profiles to have multiple #chatmail relays at once ... failure or blocking of a single relay would not disrupt chatting anymore. But multi transport also helps with the "centralization problem in decentralized systems" ... delta.chat/en/2025-06-04-surge…
(Funding is looking good currently btw!)

Delta Chat: A big user surge and funding for decentralized scale

Beginning June we witnessed a sudden surge of Delta Chat usage especially in the US and Cuba. We don’t know the social dynamics behind it but it probably helps that Delta Chat apps resiliently work...

#deltachat #chatmail

We do not aim for #deltachat to be another social media app. No #ai summaries or suggestions. No public directory of contacts. No discovery via outside identifiers (mobile phone or email). Just you and your contacts privately messaging, in a solid simple user interface on all platforms. End-to-End encryption enforced on two layers. #chatmail relays know and retain nothing, no content or metadata. #webxdc apps allow for custom interactions on top of chats.

Contributors and donations welcome!

V2 #deltachat is rolling out after weeks of internal testing, a major milestone revising how end-to-end encryption works and bringing more beautiful contact and group profiles, direct access to chat-shared apps in the title bar and a "new email" action with setting a subject for those using a classic server.

Best of all, users and developers don't need to co-ordinate anything for upgrading to V2 despite the massive security rework behind the scenes :)

Everyone returns to email in the end. We are there already. #whatsapp wants you to add your email to secure your account ... despite all the nay sayers and numerous well funded attempts and claims to kill #email not even WA can do it. #deltachat #chatmail and #webxdc are about deep collab between people, projects and operators to evolve email from within. It is not just about SMTP and IMAP and MIME and OpenPGP which are all exchangeable and can be improved ... Which we set out to do. Cheers.

#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.

Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role github.com/chatmail/models/tre…

Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. arstechnica.com/security/2025/…


WhatsApp provides no cryptographic management for group messages

The weakness creates the possibility of an insider or hacker adding rogue members.
