triptico.com 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.
Thank you very much for your awesome work, @grunfink@comam.es 🙂
The time is probably right.
Back in 2022, when I was still using iOS, I wasn’t completely happy with the Fediverse apps that were available. I was mostly using Akkoma, and the interface I liked the most was actually its web UI, even on mobile. So I started playing with Xcode and put together the foundations of an app tailored to my needs.
A lot has changed since then and today we have great alternatives like IceCubes, Mona, Ivory, etc. Each one has strengths and weaknesses though, so I picked up my old project again and kept pushing it forward.
So I’m happy to announce that my app will finally see the light: I’ve been using it for the past few days and, in my spare time, I’m fixing bugs and adding missing features. I’m building it around my own needs, so it doesn’t have to “appeal to everyone”. I wouldn’t call it opinionated, but it’s definitely targeted.
The app will have one key trait: #snac2 support will be a first-class feature, not an incidental one. Many apps, especially on iOS, support snac as a side effect, but the experience is often not optimal. In this case, the choice is deliberate and it strictly follows the Mastodon API support implemented by snac. So snac will work properly (within the limits of the platform, of course).
Among the features already implemented: the app is minimal and lightweight (under 10 MB, including debug code), easy on RAM, and privacy-first (for example it strips EXIF data from media before posting, so the server will never see it). On snac it also cleans up the "Boosted by Aoderelay" messages that appear when using a relay, removes the character limit, and supports posting in Markdown.
I also added support for Apple Intelligence to generate alt text, both for the media I post and for media posted by others that is missing alt text.
Everything is processed locally through Apple APIs and only on supported devices. The results aren't amazing, Apple Intelligence is extremely limited, but in my opinion it's the only privacy-friendly and ethical way to approach it. And of course, you can disable it.
On Mastodon it supports all the main features: lists, quote posts, granular notifications (you can choose what you want for each category), notification grouping, multi-account support, and it works.
It's still missing a few things (block, etc.) and has some bugs, which I’m spotting as I keep using it.
As soon as it's stable enough, I'll invite a few people to test it. I still haven't fully decided how I'll distribute it: an Apple Developer account has a yearly cost, and I hope to reuse it for other projects too. So this app might be paid, with a trial period, but if possible (I still need to check what’s feasible) I'd like it to be free if you connect to one of the BSD Cafe instances, illumos Cafe, or any snac instance, including your own.
I don't know how long it will take before it's ready... but I can already tell you what it will be called.
It already has a name, and it's... MastoBlaster.
This name was chosen for personal reasons, and also because of its similarity to Master Blaster by Stevie Wonder, which even today feels relevant and fitting for the Fediverse.
Stay tuned!

Acho muito válido até impulsionar novamente publicações próprias que ainda considere relevantes, quando tiver contato com elas posteriormente.
Por outro lado, pode ser importante termos uma opção de desabilitar a visualização de quantas curtidas e quantos impulsionamento uma publicação teve. Bem como sobre receber notificações disso. #Phanpy, por exemplo, creio que tenha ambas possibilidades. #SNAC já permite, recentemente, filtrar tipos de eventos nas notificações.
#snac is a pretty cool #fediverse #activitypub server software!
Super lightweight, no database, easy to set-up.
I will not replace my main #mastodon instance with it, but i really have some other use cases for it, for example some bots or so.
And from what I saw, the code also is pretty nice to learn things from it. (me, a c programming noob)
Edit: Totally dumb of me to NOT post the Git repo in the first place 🤦♂️

"#snac does not store nor cache media from other instances."Thank goodness. I tried running other fediverse servers and with just one account I was getting gigs of cache. Snac shines here.
As of now, the only way to clean media is to go to the static/ subdirectory of your user and delete the unwanted files by hand.
If you’d like to test it without compiling and building your own image, the ready-made ones I keep for my own setup are always available at https://codeberg.org/daltux/-/packages/container/snac/versions

The #illumosCafe #snac instance has been upgraded to 2.89
#illumosCafeServices #illumosCafeUpdates #illumosCafeAnnouncements
#snac, el más mejor servidor #activitypub del mundo mundial. Escrito en lenguaje C, el único y verdadero, es del tipo "instalar y olvidar" porque no da problemas y ocupa un mínimo de RAM y apenas CPU. Software como se hacía antes: óptimo.
My main (and truly only issue) with #snac is it's overreliance on filesystem operations. it's very cool from a purely unix kind of standpoint where you can see the elegance of such a design, but in practice, it's just way too much overhead Having it operate with sqlite instead, as a baseline, would already make it much more efficient than it is I do like that people are engineering stuff like this though, having the entire program be a self contained repository of readable C, that implements the basic features of mastodon, is kind of dope!
@wasteland_rider Yes I did close the ticket. The #snac instanance is running inside a #FreeBSD #jail and connected to the outside world via a #nginx reverse proxy.
What I have discovered is not 100% perfect, but login, browsing the timeline etc. ist working fine. What is missing actually are the notifications. But for this I want to open an seperate issue since the login issue is closed.
Two Fediverse clients I like are Elk and Phanpy, but both had the same issue: the inability to filter "replies" and "boosts" from the timeline. For me this is essential. I can't keep up with my timeline, and if I also see replies to posts unrelated to what I follow, it just becomes chaos. So I tried to implement these filters and opened a PR.
The Elk developers have already merged it into the main branch, so we should soon see the two hide options appear in Elk. Hopefully the same will happen in Phanpy as well, because this greatly improves the experience on two excellent Fediverse tools, which are also compatible with snac.

My friends, I'm so excited and happy to introduce a new project: the illumos Cafe!
The positive and constructive spirit of the BSD Cafe, created and maintained by all the friends who participated from day one in building a strong and friendly community, deserves to spread to other operating systems. Because there are other OSes that deserve attention, certainly more than they're getting right now.
Operating systems based on illumos (like SmartOS, OmniOS, Tribblix, OpenIndiana, etc.) are mature, stable, secure, and perfectly usable for a wide range of tasks. ZFS is native, zones are an excellent method for containerization, and bhyve and kvm coexist beautifully - and so much more, too much to list in a single post.
So from today, the illumos Cafe will stand alongside the BSD Cafe in creating a positive, respectful, and growth-oriented (but also relaxing!) environment, starting right here in the Fediverse with a Mastodon instance and a snac one.
I've written an introductory article about the project, including some technical details. I invite everyone interested to read it: https://it-notes.dragas.net/2025/08/18/introducing-the-illumos-cafe/
Choose your table, take a seat and enjoy your time at the illumos Cafe!

Con el software de ActivityPub que uso (#snac) es muy fácil montar cosas de estas.
It gives a daily report of those asteroids with a reasonable probability of crashing into Earth, in case you are not already afraid enough of the future. Of course, using #snac, what else.
It takes its data from a very cool NASA site, so (again) in these days of uncertanty, I'm not sure how long will it work.
Everyone, take care, and have a great week.

Some technical details for those interested:
The entire FediMeteo setup runs on a FreeBSD VM costing around 4 euros per month. It supports almost all major EU countries (plus the UK), with just a few left to complete. Currently, there are 25 separate jails, each running its own instance of snac, totaling 25 instances. The VM load typically stays around 10%, which increases to 30% when updates are published for countries with larger numbers of cities (currently Germany and Italy). The only time the load spikes is when new countries are announced; during that time, all remote instances connect to all cities to download their details.
As for RAM usage, excluding the ZFS cache, it's currently a total of 213 MB. Yes, MB.
Added support for subscribing to LitePub (Pleroma-style) Fediverse Relays like e.g. https://fedi-relay.gyptazy.com to improve federation. See snac(8) (the Administrator Manual) for more information on how to use this feature.
Added support for following hashtags. This is only useful if your instance is subscribed to relays (see above).
Added support for a Mastodon-like /authorize_interaction webpoint entry, that allows following, liking and boosting from another account's Mastodon public web interface. To be able to use it, you must reconfigure your https proxy to redirect /authorize_interaction to snac (see snac(8)).
Some fixes to accept Event objects properly (like those coming from implementations like https://gancio.org/ or https://mobilizon.fr).
Added some caching for local Actor objects.
Hashtags that are not explicitly linked in a post's content are shown below it.
Fixed broken NetBSD build (missing dependency in Makefile.NetBSD).
The user profile can now include longitude and latitude data for your current location.
Mastodon API: implemented limit= on notification fetches (contributed by nowster), implemented faster min_id handling (contributed by nowster), obey the quiet public visibility set for posts, other timeline improvements (contributed by nowster).
Reduced RSA key size for new users from 4096 to 2048. This will be friendlier to smaller machines, and everybody else out there is using 2048.
If the SNAC_BASEDIR environment variable is defined and set to the base directory of your installation, you don't have to include the base directory in the command line.
Fixed a bug in the generation of the top page (contributed by an-im-dugud).
Added support for Markdown headers and underlining (contributed by an-im-dugud).

Announcing FediMeteo – Weather in the Fediverse!
UPDATE: I have created an account for updates and other information on FediMeteo - follow the account @admin to stay updated!
UPDATE: Ireland, Poland, Portugal and Switzerland have just been added
Weather has always influenced our lives: from agriculture to outdoor activities, to extreme events that, thanks to modern technology, can now be predicted with greater reliability. Personally, weather plays a significant role in my daily decisions, which is why I decided to create a service tailored for the Fediverse.
FediMeteo uses Open-Meteo data to publish updates every 6 hours, including current weather conditions, forecasts for the next 12 hours, and predictions for the upcoming days. Each country is served by its own dedicated instance (e.g., it.fedimeteo.com for Italy), managed through snac to ensure simplicity and efficiency in publishing.
You can follow FediMeteo directly in the Fediverse (on Mastodon and compatible platforms), via RSS, or by visiting the dedicated page for your city (e.g., fr.fedimeteo.com/paris).
Currently supported countries include:
Austria, Germany, France, Ireland, Italy, Netherlands, Poland, Portugal, Spain, Switzerland and the United Kingdom, – with many more regions coming soon!
FediMeteo is hosted on a FreeBSD-based VPS, with each country isolated in its own jail to ensure security and scalability.
Visit the main site to explore the national instances and start following your local weather updates today:
https://fedimeteo.com
Happy weather monitoring to all! 🌦️
FediMeteo is dedicated to my grandfather, who every evening would give me the weather forecast based on TV, radio, and his personal experience. He would convince me that the weather would be bad, so he had an excuse to accompany me to school instead of me going alone.

Más tarde me he dado cuenta de que empleando el correo electrónico las discusiones no tienen sentido y que más allá del duelo al amanecer no merece la pena discutir con gente que se ha construido un personaje público y saca sus garbanzos de ahí. Entre eso y los palmeros, a los que el tuitstar SÍ responde por que necesita tenerles en cuenta, es difícil estar a gusto; de hecho el término "pocosfollower" es el indicativo de una época.
Pero sí que he pasado mucho tiempo allí obteniendo enlaces y enterándome de polémicas para pasar el rato y olvidar cómo estoy y quién soy así que tampoco es que lo haya dejado hasta el sábado. Una vez que tengo mi servidor en el fediverso (con #snac) tengo siempre un lugar que considero mío. Por esa parte estoy cubierto.
Ahora estoy intentando ver qué aparece en BlueSky y de momento están todos con una limpia tremenda de nazis y demás chusma que está funcionando al parecer. También cuentas estupendas que estaban permanentemente candadas en twitter ahora actúan en abierto y son una delicia de seguir. Pero el lugar sigue siendo extraño, como un barrio bajo asedio, y quiero ver dónde terminará cuando los dueños empiecen a monetizar.
Right so my personal #snac instance seems to be working ok and I have managed to import all of the accounts I follow here on bsd.cafe . I'll still be using this account but will try and see how I get on with snac. You may notice that it always shows that I have no followers and that I'm not following anyone. This is intentional by the author of #snac as they feel numbers should not matter which is quite true. Feel free to follow me over there if you haven't already and hello to any new followers.
@justine@snac.smithies.me.uk
All of this is hosted in my #HomeLab on a #FreeBSd server jail running over my home FTTP connection. I'm impressed I've gotten this far. Next I'll be doing some html and css customisation's to theme it a little.
After getting to try the #Snac activity pub server developed by @grunfink on bsd.cafe thanks @stefano , I'm kind of tempted to spin up my own instance. Anyone here other than Stefano that runs their own instance ? Please share you pro's and con's plus any workarounds you have come up with.
Also how are you viewing / posting on mobile ? Are you just sticking with web or using the likes of #Tusky ?

I find these "popularity contests" pointless, ridiculous and inherently toxic, and a signature of private social networks where the goal is not to help people communicate between each other.
This is the reason why #snac does not propagate how many followers nor likes a person have.
