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!
Comparing #XMPP against #email protocols is too limited. What sets #deltachat apart is *vertical integration* and being driven by UI/UX considerations. Cross-platform Apps and Bots use the Rust core library which connects with #chatmail relays and classic email servers based on a higher level API -- abstracting over SMTP, MIME, #OpenPGP etc. See chatmail.at
#webxdc apps in turn use an even higher level stable API abstracting over email/xmpp/... see webxdc.org/docs/
Chatmail provides FOSS infrastructure for interoperable, secure, speedy and reliable end-to-end encrypted messaging. Check out clients as Arcane Chat, Bots or Delta Chat today!chatmail.at
1 cent per five years .... is the current marginal hosting cost for a #chatmail address, with which #deltachat apps facilitate world-wide private messaging including interactive #webxdc apps that run end-to-end encrypted in any chat group.
<1 Million EUR per year is the estimated marginal hosting costs for 350 Million EU citizens. Such scaling requires, however, research and development, including careful UX and #cryptography work. Related writing from @gordon

The trajectory of E2E-encryption is about de-platforming: There shall be no central machines that can control the edges/peers, and the social groups and virtual centers they freely form.
Our #deltachat R&D around #chatmail relays and #webxdc apps all aim to realize such a "zero-platforms" fully E2E-encrypted interaction model. However, this is *not* just about cryptographic cleverness. Rather it is about usable anti-authoritarian designs, as explicitly stated in January delta.chat/en/2025-01-23-webxd…

Dear fans of messenger comparison sports,
How does it factor in that on #deltachat there are many apps that can be used in a chat without requiring a login or even a privacy policy ... And the apps all work like cryptpad but automatically and without requiring any server side hosting?
Editing documents and checklists and calendars are all safely end-to-end encrypted without a server and anyone can write new #webxdc apps permission free.
Which other cross-platform messenger offers this?

Just finished implementing all the webxdc.js apis, the next steps are about hardening the sandboxing in preparation for the security audit together with @WofWca

With #deltachat #chatmail and #webxdc developments we aim to instigate a new modern foundation for secure E-Mail and a resilient Web without platforms. We are building a kind of #minecraft system for modern decentralized messaging.
But who are we building it for?
For all who need reliable trustable means of modern private communication.
While our work needs hackers and experts it's not designed for them. @tante raises interesting and important related thoughts tante.cc/2025/03/03/who-is-fre…
For a while I have been arguing that maybe there are some issues with the whole “Open*” movements, their founding myths and ideologies (see for example my talk at Fluconf). This criticism comes from a place of love.tante (Smashing Frames)
Woah! You can now run 32bit operating systems (alpine, ReactOS, ...) via the new v86emu #webxdc app available at webxdc.org/apps/#mightyshadow7…
Ethernet networking uses "webxdc realtime API" implemented via @n0iroh gossip channels.
Basically VMs are wired to an Ethernet that is constrained to chat members only and uses forward-secret encryption with #p2p connections. Result: Telnet and netcat are similarly secure as signal but with Peer-to-peer networking :)
Despite not having a lot of money we are yearly subscribed to give 300eur to the #foss #forgejo platform of @Codeberg who are currently suffering sustained network and abuse attacks social.anoxinon.de/@Codeberg/1…
Some of our #webxdc developments takes place on Codeberg. Thanks for persevering! #hugops

The realtime #WebXDC APIs are built on top of #iroh #p2p connections in #DeltaChat. Glad to be playing a part in this!

The time has come for a new #deltachat_desktop Test Release: 1.51.0 !
Besides many bug fixes we added a New App Picker 🚀 which allows to browse and attach #webxdc apps directly from attachment menu.

The time has come for a new Desktop Release! 🎉 Help us find the most annoying bugs so we can make sure this update is ready to be released on the website and in stores.Delta.Chat
Upcoming events:
We'll give two talks at #FOSSDEM about #chatmail and #deltachat in the modern email devroom, on Saturday late afternoon: fosdem.org/2025/schedule/track…
The friday before, we'll probably also appear and talk about about #webxdc at the #Matrix barcamp.
Sunday morning, our friends from @n0iroh namely @flub, will give a talk about the P2P-iroh network architecture fosdem.org/2025/schedule/event…
Otherwise, you'll find us mostly around #OFFDEM for chatting and more ad-hoc sessions.
Two new #webxdc apps: a one-dimensional pacman and shopping list -- already used by many families along with "calendar" and "checklist" for daily organization. All apps are discoverable on Android via "attach/app" or in the web via webxdc.org/apps ...
With webxdc apps you'll never have to sign-up to platforms again and if you are fed up with Delta Chat, you can use the same apps with Cheogram and Monocles (XMPP messengers).
Forks welcome: apps come with source and a repo link :)
DeltaTouch 1.10.0 is out, main features:
🔹 Realtime support for in-chat (Webxdc) apps, see delta.chat/en/2024-11-20-webxd… for more info.
🔸 Improved HTML message view.
🔹 On UT 16.04 (xenial), DeltaTouch will check for updated versions.

There are sometimes discussions about an end-to-end encrypted private social media e-mail chat network 🤯 Basically you could follow delta chat profiles and subscribe and probably react to their encrypted broadcasts ....
This and many other discussions are the "humus" on which #deltachat evolves and, for example, became a super-app: Android 1.50.3 spearheads direct #webxdc app picking via the "attach" chat action. Actually #cheogram and #monocles, both #xmpp messengers, released this first!
Those of you who have to work through Google, Apple and other store's compliance, we feel you! Maintaining around 16+ target distribution sites for cross platform apps takes a constant toll on us.
One of the giant features of #webxdc app developments is precisely that no store is needed. You can just write an index.html, a .js file and pack into a zip file and everyone can use this as an app in their chats, no store needed for permission and distribution.
Are you interested in enshittification-resistant application development?
After almost two years of collaboration with the wonderful @n0iroh team, we are happy to announce that #deltachat 1.48 apps on all platforms contain top-notch Peer-to-Peer networking support, including hole-punching and forward-secret end-to-end encryption. It is exposed through the new #webxdc realtime APIs and there are some nice initial showcase apps 🎉

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

I made a quick logo for my #webxdc time tracking app. Sadly I don't possess #logodesign skills, so it does not look very good, still better than no icon.
PS: if someone wants to attempt improving it, the pr is here: github.com/webxdc/timetracking…
This is just something quick and dirty, If you have more talent in logo design please make a pr or comment with suggestions or both ;)GitHub
