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.
@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.

@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
@adbenitez Horrific! This time you won't fool me. The new features sound nice but in about 53 releases like that #DeltaChat will cease to exist!!!! 😱
#DeltaChat Spoilers 📢
The new upcoming release will be 1.19MB smaller than previous release while having a lot of more features like:
★ allow to add any chat to the home screen
★ update "forward message" icon
★ do not allow non-members to change ephemeral timer settings of groups
★ sync message deletion to other devices
★ when reactions are seen in one device, remove notification from your other devices
★ don't disturb with notification when someone leave a group
★ and more!
Did you know that #deltachat literally shares cryptographic implementation code with #signal ? Both delta and signal use the ed25519-dalek crate ... Most messengers by now moved their cryptography to #rustlang . We did that in 2019. But in delta also all networking and message formats is implemented in Rust where other messengers (including signal) have a lot of platform specific code still.
@cherti
> Also Signal has no VC funding
neither has it #DeltaChat
about your "email is bad" tale, that is just the old tired urban legend, reality shows you can actually use it and ANONYMOUSLY WITHOUT GIVING PHONE NUMBERS
> something they actively advertise as a feature
using the more secure chatmail servers is what is being actively recommended, you have FREEDOM OF CHOICE tho, not bound to a central server
@adbenitez @Daojoan I recently discovered #deltachat and I'm quite happy despite the fact I don't know anyone using it.
I didn't know about collaborative editor and 2FA, can you tell me how to use it? Also, I'm not sure on how the mini apps work or how to properly use them
@european_alternatives could you add #ArcaneChat (https://arcanechat.me) and #DeltaChat (https://delta.chat) as alternative to #WhatsApp ??
Looking to move away from #WhatsApp ? take a look at #ArcaneChat and #DeltaChat
@Daojoan sad to see no mentions of #DeltaChat or #ArcaneChat
With them you can have a messenger, encrypted email and at the same time e2e encrypted notes synchronized across all your devices, 2FA PIN numbers app, collaborative editor and many other mini-apps all without depending on a central server
@MissGayle no, the servers don't even allow to send emails unencrypted, so all the emails must be e2e encrypted, there is no data mining, in fact the #ArcaneChat and #DeltaChat apps focus on removing all possible metadata from email even if you use them with ex. #gmail, you don't even need to use https://arcanechat.me server, you can even setup your own, unlike #protonmail and #tutanota, this is not a silo that requires to use their specific app with their specific central server
@v_raton take a look at #ArcaneChat https://arcanechat.me and #DeltaChat https://delta.chat they are totally free and decentralized
@toddtyrtle just use #DeltaChat or #ArcaneChat you can have as many email accounts as you want and it is 100% free
Currently playing around with https://github.com/MightyShadow702/v86Emu-webxdc which leverages https://github.com/copy/v86 into DeltaChat. Effectively allowing you to run a 32 bit .iso file inside DeltaChat as a webxdc application.
Right now tcp/ip is wired up with realtime communication over iroh 💥 🧠
@ljrk @chiraag @tortie @waeiski @Mer__edith I wish that the #EU would clarify its stance regarding #Signal: *is the AWS hosting problematic for them or not*? Let's assume *not OK* for a minute.
As to a Signal alternative, I *wish* I could recommend #XMPP over #Deltachat today. *AFAIK*, in XMPP, #OMEMO does perfect forward secrecy/double-ratcheting - but alas, the #iOS and #MacOS clients aren't the greatest at present. That lack of all common OS' having feature parity (very reliable notifications, Reactions, etc.) makes me hesitate in recommending XMPP for *everyone* today (but it's great for geeks).
Whereas Deltachat at least has usability parity for features across each OS it supports (which I feel users would highly expect *first*, before demanding a more modern encryption). Yes, autocrypt has no perfect forward secrecy, etc. and other metadata-related criticisms. But Deltachat is simple enough to learn, *allows servers to realistically be used in the desired country*, and works on all the common platforms. It's a decent choice for *today*, as a well-rounded choice (where tradeoffs must be made somewhere). And once the XMPP clients get better (in MacOS/iOS), I'll recommend XMPP as a goto *then*.
@waeiski the elephant in the room there, is that #Signal servers are said to be mostly on Amazon AWS.
Maybe they are thinking of an alternative like #Deltachat (with a posteo.net email address, or other such auto-encrypted email address not hosted on US soil)? This alternative exists right now, it's just that posteo.net addresses are not free to rent. Merely inexpensive. It's cross-platform: is said to be stable, even on #MacOS and #iOS or #iPadOS
@waeiski I just installed Deltachat from f-droid, and it offers to create a free email account (supporting autocrypt) with a server called nine.testrun.org (located in #Amsterdam).
So I guess #Deltachat is free to use in that sense. I'm using this test account to E2E-encrypted chat with my posteo.net account in Deltachat in #linux.
#Android
@maple #ArcaneChat is an android client for #DeltaChat, and Delta Chat is available for #iOS, #Windows, #Linux etc.
and now that you talk about young people, in several places people are not even allowed to get a SIM card at all until certain age, so apps like Signal that depend on phone numbers are a non-go, while I have seen several people using DeltaChat with their children, ex:
Porque todos los días son de terminal. #newsboat + #podboat para leer/oir feeds (incluido podcast o algún video).
El compa @libretics lanzo su podcast, hace un rato (lo paso por #deltachat y #xmpp)
Aquí la url https://podcast.libretics.org/@libretics/feed.xml, por si quieren darle una revisada o suscribirse. Ya saben, I ❤️ #cli Enjoy!
@sesivany I really recommend you to give a try to #DeltaChat anonymous login without any phone number or any private data required, you can create as many accounts and add as many devices as you want, all work smoothly no encryption problems with multi-device etc and it has a better interface than #matrix on the level of #WhatsApp and #Telegram super user-friendly and painless to onboard family and friends
And you LITERALLY own your data and can browse it and search it offline
@Andromxda letting people know there are other options and expressing your opinion is not "sending spam" or now anyone that doesn't agree with you in how perfect and "state of the art" is #Signal is a spammer to you?
#DeltaChat is not an "obscure messenger", says the fanboy of a messenger that even makes you solve a CAPTCHA puzzle on registration and make misleading blog posts about how Signal "doesn't depend on phone numbers now" that everyone misinterpret and spread fake news
Multi device setup with #deltachat only works within the same WiFi even though @n0iroh is integrated, a production quality P2P networking library for all platforms, with hole punching etc.
You may regard delta's "same wifi" restriction for multi-device setup as an additional protection against phishing attacks like Signal lately suffered https://cloud.google.com/blog/topics/threat-intelligence/russia-targeting-signal-messenger
Moreover, if your wifi does not work you can do a mobile hotspot and use that for transfer. No DNS/internet needed. Thanks Iroh :)
@f #ArcaneChat and #DeltaChat are also good decentralized alternatives for private chatting, take a look at:
@jcgonra21 #DeltaChat is even easier to use and register, no need for phone numbers, SMS verifications or solving CAPTCHAs, this also mean that besides the eldery, it can be used by the kids that don't have access to a SIM card yet, to chat with the family
if you are using #android take a look at #ArcaneChat a Delta Chat client for android:
@Tutanota an #email provider talking about alternatives to #WhatsApp and casually overlooking #DeltaChat 🧐
📢 ability to edit messages coming "soon" in upcoming version of #ArcaneChat and #DeltaChat 🎉🥳
This week in #FDroid (TWIF) is live:
- the faster you test 1.22.0 the faster the #MaterialDesign3 UI update is released. Do.Your.Part!
- #DeltaChat and ArcaneChat tell stories about #RIIR
- #emacs is more complete
- #CLT2025 sched app is live
- monitor your #BTC mempool
And 100 more apps in the news at https://f-droid.org/2025/02/20/twif.html
@johnoestmannmusic it is "open source" in fact the code doesn't really fully match, and when I tried to use part of it, it turned out some data was completely wrong in the repo (ex. JSON file with emoji data needed for emoji picker which would then be fetched from signal server the correct file)
I recommend the #DeltaChat platform, if you use android take a look at #ArcaneChat, a Delta Chat client I maintain:
Even though #Signal *itself* has sound security - taken in isolation - it's always moored in an ecosystem (that of smartphones which run #iOS or #Android) which, by default, have #AI set up to shoulder-surf Signal, sending reports back to the mothership. In #iOS, that AI is called "#Apple Intelligence", and in #Android, it's called #Google Assistant. Repeat, these are on by default. *Only a small percentage of your family and friends will pain-stakingly disable these.* Sure, Signal itself is secure by default, but "a chain is only as strong as its weakest link*. And the weakest link is the ecosystem which Signal is moored in - that of smartphones policed and patrolled by AI, which report back to their respective motherships *in a strong majority of cases*.
Alternatives like #Deltachat (for normies willing to open their wallets to rent an auto-crypt-compatible email address) and #XMPP (easily free to use, however realistic and mature only for non-iOS-users at present) *don't* require smart-phone "moorings" - thereby making possible the dodging of the almost-pervasively AI-patrolled ecosystems.
#deltachat is a minority messenger today and that's just fine for now. Changes often come from the precarious fringe which has to make ends meet, under hostile circumstances. Our approaches are aiming to provide working software that does its damn job. No unable to decrypt, no going for VC/Blockchain money, no bending the knee and no endorsing of corporate platforms. The #chatmail server network implements #interoperable #cryptography , does away with shady spam lists, catering for #Gmail etc
@obsoleszenz finest hand craft, as #deltachat is. no bulk ware or #ai bullshit
kill that cat! you can print as many stickers as you like: it is still https://delta.chat, REALLY! #catsofmastodon #caturday #deltacat #deltachat
@sirjofri@pleroma.envs.net @peter @rosano @sirjofri@mastodon.sdf.org yes, choosing a server upfront is tricky especially if it feels like a life-time decision. With #deltachat you can migrate with all "guaranteed encryption" chats to another server later. So the initial choice is not so important and delta offers "create profile" and "agree and continue" without asking for phone number or email. People don't even need to know it's email. It works without people knowing that is a current design guideline for our ongoing devs
@rosano @peter @sirjofri @dansup sure we as many others are very happy about pixelfed and all of the other fantastic Fediverse dynamics in so many corners 💜
We are happy with many people discovering that onboarding with #deltachat is easy ... while we are working on massive scalability to actually be able to move towards many hundreds of millions of users without incurring signal's cost and with an actually decentralized and resilient and blind transport layer. Not 100% there .. yet :)
Public service announcement:
1. If you want to link your #Fediverse profile to a chat account please consider just saying "DM me for #deltachat invite link" and NOT PUBLISH it to "all".
2. If you do publish invite links to groups and so on, please consider doing it with a dedicated delta chat profile that is not your private profile. Multi-Profile for the win.
3. We want to evolve the #securejoin invite link UX to better prevent unsafe practises. Involves tons of considerations. 💜
@adbenitez I bet you're lying! You chat #encrypted using #ArcaneChat , not #DeltaChat !
Roses are red,
Violets are blue,
I chat #encrypted using #DeltaChat,
and you should too 🥰
it is extraordinary, how #deltachat #android, over all the years, with all the #features added, did manage not to grow in size
- version 1.0 from 2019 was 64 mb
- today's 1.54 is 53 mb :)
✨ My first technical blogpost is out now. ✨
If you ever wanted to learn a bit about how
#deltachat works internally and why we have two ways to communicate with our #rust core, then this is the introduction to read
Interested to take a little tour through how #deltachat apps and the #rustlang core library are wired together?
@treefit and @WofWca provide a deep-dive into the history of apps migrating from a C-Foreign-Function-Interface to a #Rust based JSON-RPC mechanism, with entertaining horror stories like how an iOS release some years ago could delete profiles without the user intending it 😬
The post also highlights a few areas where folks interested to help could start ... https://delta.chat/en/2025-02-11-why-jsonrpc-bindings-exist
@13merleperle.bsky.social Versuchen Sie, #deltachat, in Deutschland hergestellt, dezentralisiert, keine Telefonnummer oder Zahlung erforderlich, völlig anonyme Konten
@BoogieMoscovitch at the end of the day Signal is also centralized, requires phone number to register etc
I recommend giving a try to #DeltaChat, it is decentralized like the fediverse and no private data is required for registration or collected on any server, just set a name and avatar and you are good to go (only your contacts will see the name&avatar, it is transmitted e2e encrypted)
@TheZeldaZone if you already have encrypted email, give a try to #DeltaChat it is basically encrypted email displayed as a chat app like #Signal, no need for phone numbers etc and your contacts can switch easily since the app allows creating anonymous email account on the fly, all they have to do is set a name and avatar, unlike SMS verification and CAPTCHA puzzle solving of Signal registration which is more complex
The #chatmail #fosdem talk from @compl4xx is public. It goes into topics such as
- why chatmail servers?
- how to setup a server with your child
- (avoiding) spam filtering
- metadata and guaranteed end to end encryption in #deltachat
- #cryptographic #interoperability for email message routing
Thanks to attendees for the great energy even if was the last talk on the day and also for questions and conversations afterwards!
Delta Chat is since some years gaining usage by people forced to flee. Several of our contributors themselves migrated and others fear they might soon have to. Our technical designs and social approaches rest on a #RightToExit on virtually all levels. No walled gardens. No presidents.
It's true that #deltachat is a money-poor project compared to mainstream messengers ... But the question at hand in 2025 is: which messaging system will persevere when corporate platforms get corrupted and break?
Ah por cierto...ya estoy por #Deltachat
@Willow I recommend you to try out #DeltaChat it is super easy to setup, no phone number or SMS verification, no CAPTCHA puzzle nonsense, etc
if you are using Android give a try to #ArcaneChat a Delta Chat client:
@crazypedia yet another centralized service? have you tried #DeltaChat ???
if you are using Android give a try to #ArcaneChat a Delta Chat client:
Six times so far ... is how often important parts of #deltachat were independently #security audited and analyzed. Thanks to IncludeSecurity, Cure53, Applied Crypto Team at ETH Zuerich and Radical Open Security.
Last audit is from December 2024 covering @rpgp , the minimal #OpenPGP Rust library that is gaining traction with others projects as well.
Shout-out to dignifiedquire and @hko for their excellent maintenance! For more info on Delta Chat related security audits: https://delta.chat/en/help#security-audits
@S1m @delta the code you point to is not used unconditionally in #deltachat:
- tech-savvy users can use #deltachat from #fdroid that does not include #fcm. instead, it uses the same techniques to run efficiently as #unifiedpush is doing
- for non-tech-savvy users using out-of-the-box phones: these phones kill apps, and unfortunately you need #apn, #fcm & co if you want reliable instant delivery. which you want if you want to compete :)
stance of today, all that gets re-evaluated often :)
With our #deltachat #chatmail and #webxdc efforts we put all intelligence on the end devices, and architecutally separate it from a transport layer that routes safely and fast but knows nothing.
There are a dozen or more #chatmail servers across many jurisdictions, all safely interopable with each other and classic servers.
Turned out we can dumb down email servers by relying on cryptography instead of IP reputation and ai/spam filtering. And have 200ms delivery times. We are not done :)
Did you know that #deltachat does not need and does not use key servers? Most other messengers (wa/signal/matrix/threema/...) actually operate or incorporate a cryptographic key server, managing the cryptographic identities of all users. Delta Chat uses decentralized protocols for key management avoiding a central storage of identities. The SecureJoin protocol is the key (sic!) innovation and was independently analyzed by ETH Zürich researchers earlier this year .... https://delta.chat/en/2024-03-25-crypto-analysis-securejoin
How many people do you know that have lost their messaging history on Whatsapp or Signal, photos etc during mobile phone transitions or breakage or through other shenenigans?
With #deltachat you can:
- export "everything" to a file and import it on any of the many different devices
- or just setup a second device through a QR code scan -- which was happily discovered here after an accidental factory reset https://libranet.de/display/0b6b25a8-2066-0695-ca24-081964494389
