taquiones.net is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
The tech oligarchs, embodying and collaborating with authoritarians, are the horror artefact of the immense power that lies in configuring and operating our digital infrastructure we live and love on. Cryptography may mitigate toxic infrastructure but eventually we need to find and arrange more convivial ways for going about our lifes. #deltachat and #chatmail are small contributions to people-sovereign convivial infrastructure. DM us if you need support setting up a new chatmail relay :)
@Thomas1108 we hear you. Changing messengers is serious work. There is no need to rush if you just moved to signal. It's a fine choice. For the time being, it would be suicidal for the US corporate operators of signal's infrastructure to use their power to compromise it. They could loose tens of billions of revenue with customers outside the US if they did. Maybe just consider #deltachat your insurance and a thing to eye mid/long term. Email will not go away anytime soon :)
I said it before on Mastodon. I'm reposting this again. Comparing #DeltaChat and #Matrix together, if you want hassle free and consistent messenger for private #E2EE chats, don't go for Matrix. DeltaChat is way better.
However, if you want something like a public forum, or a public chatroom, don't go for DeltaChat. Matrix is way better suited for that. And DeltaChat does not support public groups at all. In DeltaChat groups, there is no admin or moderator and everyone have got permission to remove or add the others.
I think I have to write a longer post on my personal blog about these two, comparing them together.
PS: Another Matrix encryption bug few minutes ago triggered repost of this.

Delta.chat seems pretty neat and one of the few times PGP is implemented in a user friendly way.
I very much appreciate that it builds on top of email.
Lack of push for self hosted servers is a bit of an inconvenience, I’ll have to look into running my own with push proxy I assume? #deltachat
@adbenitez @ucas @happybuddha How do I get access to this in #deltachat ? Is it a group or a bot?
@symcasolari a thing that has lot of potential for convincing people is the in-chat mini-apps of #DeltaChat which Signal doesn't have, with them you can have shared to-do lists, shopping lists, split bills (I am using it right now to split expenses with a friend while traveling and it is super cool), mini-games, collaborative editor, polls, etc. There is much more than just chatting and could replace dependency on several centralized services, also kids can use it without SIM cards
@opensourceopenmind if you don't want to use phones or SIM cards just use #DeltaChat https://delta.chat
@triskelion #Telegram "apps" are literally just a normal website opened in a webview, so it has all the problems of using a normal website, they have access to all your data and if the website goes down you lost everything, also for obvious reasons can't be used offline unlike #DeltaChat apps
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?

Awesome, the new Delta Chat Desktop Client for Linux Mint has arrived.
Now I can edit and delete messages after sending them.
Fantastic effort devs.
Another great leap forward in messaging technology.
Thank you folks.

There might be a slight oversight in removing *all* key management options from the apps. What about *only* exporting and importing account keys, possibly with all contact keys (ie without all chat history)?
#deltachat ‘Edit and Delete Messages’ changes are impressive!
I would appreciate a link to the pull requests where the exact changes are explained in more detail, right from the app changelog. The amount of repos involved is staggering and I would not know where to start searching. In any case:
¿A alguien le interesaría montar un grupo de #deltachat en español para probarlo y cacharrear un poco?
#Deltachat es un sistema de mensajería con el cifrado por defecto, que no reinventa un nuevo protocolo para estandarizarlos a todos (ver: https://xkcd.com/927/)
@phillip me being able to sync the full years-old history of my #ArcaneChat / #DeltaChat apps across several devices without needing any server, even while being offline just connected to the same wifi and without needing a "main/master" device, without depending on phones or SIM cards:
@reallylazybear I hate to be the bringer of bad news, but you are bound to get problems, it seems they require you to re-connect with the phone from time to time, it seems it doesn't really support multi-device without a dependency on a main device, for an app that has good multi-device without phone numbers check #ArcaneChat (https://arcanechat.me) and #DeltaChat
for problems with signal multi-device see:
https://framapiaf.org/@jeeynet/114177155835278699
@gabriel_andres please take a look into #ArcaneChat (https://arcanechat.me) and #DeltaChat (https://delta.chat)
good #decentralized alternatives, user-friendly for family and friends, no phone numbers or any private data required, painless configuration, just set a name and avatar and you are good to go, no SMS verification, no CAPTCHA puzzle solving, no SIM cards, kids can use it, also multiple devices supported without need of main phone device, and in-chat mini-apps! totally #e2ee
@hans if you are going to give it a try you can join this community group for testing and asking questions to other #DeltaChat users:
https://i.delta.chat/#6CBFF8FFD505C0FDEA20A66674F2916EA8FBEE99&a=invitebot%40nine.testrun.org&g=DC%20Community&x=y6dS91dlLLi&i=0bzEm4zAacX&s=GQQlKuqD-zH
#Signal took a huge bet that running on US big-tech toxic infrastructure is fine because its groundbreaking and industry-shaping cryptography is crafted to neutralize it and keep users safe.
But is it really feasible to live on toxic infrastructure in the longer run?
#deltachat rather takes a bet on the massive e-mail server network and interoperable protocols, and on #chatmail servers which enforce message encryption and metadata-minimization.
Delta is for when centralization turns sour.
Now everyone in the Netherlands is moving from #whatsapp to #signal , I am adding @delta to my chatapps (Signal and Matrix).
#deltachat is E2EE, EU based 🇪🇺 , can be used decentralized and is fully FOSS. It looks to be on-boarding friendly and very similar to what people are used to.
Let's see how it works in practice!
@jeeynet taking the opportunity to switch to #DeltaChat that doesn't require phone numbers, send the picture to your contacts and now that you have an actually reason/problem to switch is a good chance to move to something decentralized without phone numbers or any private data required,
multi-device is much better in DeltaChat, you can have as many as you want and every device is completely auto-sufficient without needing a main device
@lienrag @natacha @nicoco @jeeynet all issues from the ETH Zuerich security analysis were addressed.
There are more audits with the last one being on the Rust #OpenPGP library rPGP where also all issues were addressed.
Maybe even more importantly, #deltachat is focused on actual security outcomes for journalists, lawyers and activists in repressive countries. @Xeniax has done extensive user research and real-world testing. Many findings have been incorporated and addressed in Delta Chat.
Ne serait-il pas possible pour l'application de prendre pour titre le "sender" au lieu du "subject" de l'email ? Cela réorganiserait bcp mieux les choses...
#DeltaChat
Great feature's and good feedback conversation. Thanks devs. Top effort.
I've got the Google Play/Aurora update, thanks.
Any ETA on the Linux client?
Cheers.
@runbox @european_alternatives that doesn't even include #DeltaChat ☹️
Another useful feature of Delta Chat.
My Delta Chat app is synchronised across 5 devices. 3 Android phones(1 x Google, 1 x LineageOS and 1 x GrapheneOS), 1 MacBook Pro/Linux Mint 22.1 laptop and a Mac Pro 5,1/Linux Mint 22.1 Desktop.
Each profile within the app allows for "Saved Messages". So if you save a note to yourself as a message and post it on one device, it is available to all implementations of the app.
For example, I recently needed to keep a diary of blood pressure readings for a week for my doctor(coz' I'm an old bugger).
I recorded these readings as notes in Saved Messages on my laptop and when I needed them, sitting in my doctor's office, they were on the mobile phone I had with me at the time.
I'm not sure what the security implications are around this, but from experience, its one of the easiest note keeping and sharing apps I've ever come across, particularly as a cross-platform option.
Brilliant little feature well worth considering the app for in it's own rite.
@ElizabethLee you might want to reconsider it:
first, Signal is centralized and depends on phone numbers
second, with #DeltaChat you can use mini-apps in chats, including an app similar to Aegis that you are using, but Aegis is an android app, using the tool inside Delta Chat in your "Saved Messages" notes you can have your 2FA tokens synchronized (with e2e encryption) in all your devices without having to add them manually or the risk of losing them and needing manual backup
#deltachat as an alternative to Signal.
There is no shortage of startups and enterprises animated by, or outright proclaiming, replacing e-mail as the de-facto open internet messaging standard. VC Investors are forever fascinated by funding such endeavours. #matrix #simplex #slack etc are examples.
#deltachat endorses e-mail but reconfigures and repurposes it to serve for interoperable instant messaging. The #chatmail server network relays end to end encrypted e-mail only, and servers are reduced to dumb store-and-forward relays.
@n0iroh @Frando Nice! 😍 So we will have audio video calls in #deltachat in… two weeks? three?
Better be in one or I want my money back!!!
Another #deltachat release highlight that we didn't tell about yet: De-duplication of attachments and media files. De-duplication means that if you share a larger file to multiple chats, it will only ever exist once in each sending and receiving device's storage.
Same for #webxdc apps -- so if you use the 650KB big "v86emu" app running 32-bit ISO images, it will also only exist once in storage, even if each instance in a chat creates its own realtime LAN. Mini-tutorial https://chaos.social/@delta/114161626183191989
> Europe needs independence from the US [...]
> Whatsapp> signal
Signal is from US, and operates in AWS servers...
take a look at #ArcaneChat https://arcanechat.me
and #DeltaChat https://delta.chat
@Sagaliciouzzz take a look at #ArcaneChat https://arcanechat.me it fills all the checkboxes in your list plus it is decentralized and super easy pain-free anonymous registration without requiring any personal data or phone numbers. You completely own your data and can be used in several devices and have as many accounts as you want. It also have in-chat mini-games and collaboration tools like editor, calendar, shopping lists, etc all #e2ee
ArcaneChat is fully compatible with #DeltaChat
@feld what's this Deltachat thingy?
I'm getting that it uses email underneath it all. But is it any better in UI/UX than, let's say: Element (Matrix) ?
Finally finished moving all my two factor authentication accounts to TOTP app and can now uninstall Authy!
Some of the services that work fine:
- codeberg
- mastodon
- github
- npm
- microsoft
@adnan IMO, no. I know how big of a challenge it is to get a group to switch communications apps & in your situation I wouldn't.
I still trust #Signal & use it for my groups. If someone were just getting into using encrypted chat, then I would recommend #DeltaChat. I haven't experienced any buggy glitches, it has more upside & I love the community being built around it. It wasn't any harder for me to start using than matrix or mastodon.
Have I told you the good news of Delta Chat?
I use #Signal & like it a lot. I've played around with #DeltaChat & it's got some killer features that Signal doesn't. This is coming from a non-techie, but it uses encypted email in the background & nothing is stored on anyone's server in any country.
That's all awesome, but even more than that it's FUN! Itallows you to do things like play games in the chat with people making FOSS apps for it, I guess.
@feld can probably answer any tech questions, but I wanted to give it a shoutout.
https://friedcheese.us/objects/8dc022a1-438c-41f7-986a-f8e752a3e7c8
@adbenitez hola compa. Pues a impulsar el uso de #deltachat entre los hispanohablantes, que solo parece tierra de cubanos. En fin, mucho animo y a continuar.
@neil #gmail can be used with #DeltaChat gmail allows to create "app passwords" that can be uses by 3rd party apps to login, in theory #outlook has the same feature but it seems they shamelessly make it stop working silently
You can see more info about classic email providers and Delta Chat compatibility here: https://providers.delta.chat/
@ditol you can join the community group if you don't have friends yet using #DeltaChat:
@mathilde @neil @signalapp By all means, continue using Signal if you are happy with it, and have all your friends and family and activists there. Some people see advantages with #deltachat especially regarding arranging shopping lists in a chat, or "splitting a bill", or a checklist for preparing a joint travel. Anyone can attach such an "app" to a chat. Some others enjoy that devices can be set up without requring a phone number especially for children, see e.g. https://gladtech.social/@avoca/114097638574628729
@avoca @a10n @Cnoceda #deltachat is geared towards private group chats. In small groups technical moderation is not so important. A subset of people can always create another chat simply and continue there. Technical admins can only help so much. Maybe it's even the admin that is the problem?
There are >100 people chats e.g. from #38c3 or #fossdem25 that work quite fine. But YMMV
If you want Telegram-style channels with public subscription, then yes, some administration is needed.
Yes, I've just checked, and there is a message delete function.
How it works in terms of group moderation I'm not sure.
My basic understanding is each group member has the same rights/power.
I am unaware of an 'administrator' function though.
Everything You Think You Know About DeltaChat Is Wrong
https://blog.feld.me/posts/2025/03/deltachat-is-actually-good-though/
"email is inherently insecure, email can never be secure, it leaks a LOT of metadata and only the body is encrypted, subject can NOT be encrypted, you can NOT build a secure system on top of email"
#email #privacy #security #decentralization #e2ee #encryption #metadata #ArcaneChat #DeltaChat
@feld another point people miss: unlike on #Signal, #WhatsApp, #Telegram, etc where there is a central server watching all the social graphs of the whole network, in #DeltaChat and other decentralized platforms like #XMPP what a server can see is pretty limited and fragmented, We started talking about activists btw, and having the freedom to choose a server instead a central server potentially collaborating with your enemy is a killer feature
I can change my email address to another random one in the client -- even to a different chatmail server -- and all my chats will keep working. As soon as you send a message to your peers they will update to your new identity. This is a feature called AEAP -- Automatic Email Address Porting and hopefully soon we'll see a mechanism implemented that automatically enables forwarding of your old address to your new address (to not lose messages from people who don't know about your new identity yet), and then #DeltaChat can enable functionality to automatically rotate you through new anonynmous identities transparently.
@Some_Emo_Chick as alternative to #WhatsApp there is #DeltaChat which is more user friendly, for Android there is the #ArcaneChat client:
https://arcanechat.me
@feld @collectifission @davidbenque @sirjofri #deltachat for many years did not have push notifications on android and worked fine on most phones. In some cases people had to enable a permanent background notification to keep IDLE alive. But most often, messages are received in the background on Android without push.
@Andromxda I am using #DeltaChat to chat with my family since years, that is why I started contributing, I don't use #WhatsApp nor #Signal and all my family and friends are amazed at how easy and pain-free it is to onboard on Delta Chat, just setting a name, and that is it, no SMS codes, no captcha no BS, then just scanning each other's QR or clicking an invite link, no manual typing phone numbers etc.
@mikalai good point! The first years we had to make do with classic email servers. We barely expected anything else than "send message" and "receive message" to work. There was no way to get big email providers to change anything. When we then went for the #chatmail concept it meant the server doesn't need to do anything than to transport the message. No metadata, no rooms, no group state that most other messengers keep on their servers. Crossing out server state makes #deltachat p2p-ish
@k3fnb just because #DeltaChat uses the email protocol you are making some wrong assumptions that only apply to classic email, sure if you go doing activism using #gmail that is not safe, but to use Delta Chat, you don't need to provide ANY personal data / metadata and hence can't leak metadata, you can create an anonymous account for a protest and throw it away afterwards, if cops get your phone they get random contacts not phone numbers unlike in #Signal etc.
Today is a good day to familiarize yourself with the Russian concept of "managed democracy".
& to download #Signal and/or #DeltaChat
The downside of our project approach was that we often got experts being very dismissive on re-using email and #OpenPGP ... and there still is some opposition which often subsides when actually trying #deltachat and #chatmail, looking at security audits and our strong usable security focus.
There may also be surprising upsides. The UK "Online Safety Bill" which attacks end-to-end encryption integrity seems to not apply for ... e-mail. Because everyone knows, e-mail is unencrypted, right? :)
After trying out #deltachat and #arcanechat, I've discovered the #webxdc app store. My Dad loves #Sudoku puzzles, and I was tempted to play some competitive Sudoku with him. What assurance is there that there are no sketchy apps in the webxdc app store? Can these apps break out of their little jail, and root my phone? What would the #infosec community say? There's somewhat of a thread on the "threat model"/security of webxdc here (but I think it still needs more scrutiny):
https://support.delta.chat/t/webxdc-threat-model/3018
#puzzle #puzzles #competitive #game #multiplayer
The comfy feature I'd like but has security implications would be link previews. There's a bot you can add to a group chat which will produce the "quick view" or whatever of a page which is a static HTML snapshot but traditional link previews are nicer as it's rendered as part of the original message.
Besides the security implications of it there's also the uphill battle of sites breaking link previews because of AI scraping concerns so they whitelist iMessage/WhatsApp/Telegram access which screws everyone else over. I see it with Pleroma sometimes -- links won't get a preview because they 403/404 or just don't include the meta tags
Decentralizers, attention! :)
Last #deltachat releases introduced stable #p2p group membership not found in any other messenger. Members can add/remove peers also while being offline, and when everything comes online again, everyone has the same consistent membership view. We formalized and ran a simulation model using #TLA+ (invented by Leslie Lamport of vector clock fame):
https://github.com/chatmail/models/tree/main/group-membership
and a complementary #pytest model with more corner cases tested here:
https://github.com/chatmail/models/blob/main/gmc/test_gmc.py
@ezmyrelda TIP: when talking about #DeltaChat it is better to use the hashtag than only mentioning the delta chat account, because that way people like me that follow the hashtag can get your post :3
@lns 99.9% of my email communication is e2e encrypted, I am using #DeltaChat since years, never managed to actually use encrypted email in any other way, ex. why should my mom learn how to use GPG? meanwhile she and several family members that are new to phones are sending #encrypted #email to me every day without even realizing it
Dreamed of for many years, and now it became reality:
Delta Chat UI running in a web browser. 🤩
(read thread for more info)
@Cnoceda you can use your own email account or server as long as the provider allows you to use 3rd party email clients (ex. #outlook doesn't work, #protonmail and #tutanota doesn't allow it, etc)
About #ArcaneChat, yes you can import your profile from #DeltaChat
to ArcaneChat and the other way around, they are fully compatible
@qgustavor about the "many apps" that do crypto (I guess you are talking only about CryptoText and CryptoWisper?) apps are from 3rd parties, and yes, that two apps are a bit useless to use inside #DeltaChat, you could share the output to other insecure non-ecrypted apps tho, but I also would not trust the security of such apps it is just some amateur trying to create little apps
in any case mini-apps don't need to implement crypto as they benefit from encryption in DC automatically
Tengo más clientes de @delta que contactos que lo usen. Es una pena, porque me parece muy interesante, es casi un hack ingenioso para convertir el email en mensajería instantánea
@bjoern @teufel100 Seit April 2024 ist die Benutzung sehr einfach geworden, als "instant onboarding" mit hilfe von #chatmail servern hinzufügt wurde, und auch sonst viele UI Verbesserungen eingeführt wurden. Ein 3rd party Erfahrungsbericht: https://gladtech.social/@avoca/114097638574628729 und dann gibts noch mehr beim #deltachat hashtag
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 https://tante.cc/2025/03/03/who-is-free-software-for/
https://arcanechat.me server reached 1500 users!!!
the server is using around 1GB of RAM, CPU is almost unused, and only 1.4GB of storage used for encrypted user volatile data, that is around 1MB per user on average!
the cost of self-hosting a #chatmail server for #ArcaneChat / #DeltaChat is really low! and you don't even need to trust the server operator or even the VPS provider if you are selfhosting since all is #e2ee and safe against #mitm thanks to the green checkmark in chats
@bgtdsword great stuff -- maybe use #deltachat hashtag?
@jpdvm2014 hosting a chatmail server is always welcome but not necessary. Each chatmail instance can typically serve 10K's or 100Ks of users easily. Chatmail servers are more like routers than classic e-mail servers. They constantly forget messages, and #deltachat generally uses e-mail servers only as ephemeral transport, rather than persistent message storage.
#deltachat community milestones:
Dec 2023: first #chatmail server
Feb 2024: iOS push notifications
March 2024: ETH Zuerich #security analysis
June 2024: Instant onboarding on all clients
Nov 2024: #P2P #webxdc realtime and home-screen apps
Dec 2024: rPGP #security audit, 20 known #chatmail servers world-wide
Jan 2025: new #webxdc store, UI integrated app-picker, webxdc push notifications.
Spring 2025: is coming :)
money used: ~600K EUR, a tiny amount compared to other messengers.
Finally convinced my non-techy family member's to move from Signal to Delta Chat messenger.
Setup was a piece of cake and we now have 4 x iOS devices, 3 x MacOS laptops, 2 x Windows laptops, 3 x Android devices, including 1 x GrapheneOS and 1 x LineageOS,, and two Linux Mint computers connected seamlessly as one Family Chat group.
Not one single byte of personal information required nor a single SIM card needed between us, though of course we all have them.
The security benefits and other bonuses provided by Delta are great but the key here was a de-centralised messenger that allows easy setup for family groups across multiple platforms.
Well, that's it! I am completely open source finally. No Google account. No Apple ID. No Microsoft, Meta, etc accounts.
The only organisation's who have my real email address are my bank, my government and my education providers.
@scy @dequbed @joinjabber @sten @mxey
Delta Chat is used in, and designed for, people in repressive environments world-wide, and has some proven track record:

@Oneleggedjedi welcome, if you also want to move away from US-controlled messengers, like #WhatsApp, #Signal, #FacebookMessenger etc. Take a look at #ArcaneChat and #DeltaChat
> "As for me, webxdc apps makes me as adverse to it like when Signal added payments: it sounds like feature creep, and IMHO"
OTOH, that feature is what makes the app a bit special, all other messengers have same or more features as #DeltaChat, why to switch then? some people do because the mini-apps like shopping list, etc. and I don't understand why you say it is "feature creep"
the app keeps developing and adding nice features, in other areas, several added this year!
@AboutSignalNL better to switch to #DeltaChat that is decentralized, not a central service
for android there is a nice client called #ArcaneChat
@mray btw, that is Google Play, if you install #DeltaChat via #fdroid it is between 24 and 26MB
and #ArcaneChat is only 13-15MB in #GooglePlay and 17-18MB in #fdroid
