I started a short blog series to share my experience creating a custom feed for Bluesky — a pet project that started as “let's build a triathlon feed” and (spoiler alert!) now can be used for any topic : ) https://cuducos.me/building-a-custom-bluesky-feed-part-1.html

@jimray.bsky.team: "We're proud to be supporting npmx with a $6K grant as a part of our ongoing ecosystem support. (...) The atmospheric web is bigger than any one application, and projects like npmx are exactly what it looks like in practice" 💙 Thanks a ton, Bluesky team! Cheers to the social web!

I'm thrilled to announce that I'll be joining Bluesky as interim CEO. I deeply believe in what this team has built and the open social web they're fighting for. More here: toni.org/2026/03/09/c...

We're so excited to support @thisismissem.social's work bringing FedCM to the open social web! atproto.com/blog/working...

there aren't many folks who can bring such a full picture to the W3C on decentralized login the way @thisismissem.social will be able to. this is great news for atproto re: steps towards a browser-native login experience, and other ecosystems will benefit too. i will be following along closely!

one account wherever you go ☺️ your handle isn’t just for one app anymore ! we took @hello.pckt.cafe for a walk across the atmosphere

Almost 5k 🚀 let’s get there today - tell your friends! 🇫🇷 On passe les 5,000 aujourd’hui? Parlez d’Eurosky à vos amis! 🇪🇸 ¿Llegamos a 5,000 hoy? ¡Cuéntaselo a tus amigos! 🇩🇪 Schaffen wir heute 5,000? Erzählt euren Freunden von Eurosky! 🇳🇱 Halen we vandaag de 5,000? Vertel je vrienden over Eurosky!

We're rolling out a change in image format. If you see some images taking a second to load today, that's expected.

The blacksky.community web application now uses our own API servers to load posts, timelines and profiles. When data is missing (accounts on the edges of the network, outside of our primary community, etc) we leverage @microcosm.blue

Congrats to the team @tangled.org!

huge! congrats @tangled.org :)

I'm building on atproto because building infrastructure like "Drafts and Scheduled Posts for every atproto app" is easy as 1-2-3 and as cool as alf. Announcing alf, the atproto Latency Fabric: leaflet.pub/p/did:plc:3v...

🔴 LIVE https://stream.place/pfrazee.com And we are live with office hours!

new blog post on permissioned data in atproto! this one introduces "buckets", the protocol-level primitive for shared access control. I walk through two approaches that don't quite work and land on something that I think does let me know your thoughts!

It's been almost one full fortnight since our last one, we're doing office hours again this Friday. And we're bringing special guests to talk all about building on atproto. smokesignal.events/did:plc:lysq...

New blogpost about atproto It's not federation, it's not a p2p mesh. It's a secret third thing: practical. www.pfrazee.com/blog/practic...

Did you miss @zeu.dev teaching us about ATProto No worries! Check out our conversation on the Web Dev Podcast, then code along with us on Learn with Jason. WDP: codetv.dev/series/web-d... LWJ: codetv.dev/series/learn...

What even is the AT Protocol? @jason.energy and I talked about @atproto.com and what the future of social media can look like, where users are in control and developers are given more interoperability opportunities

yes! sync 1.1 leans into the end-to-end principle: end consumers (e.g. apps) perform their own verification. technically relays don't have to! but what makes a *great* atproto relay? a great relay protects consumers from garbage and network abuse, which is why indigo/relay verifies the events.

sync 1.1 made atproto relays dirt cheap. also... computers are fast.

the full PLC story relies on: - independent governance - public, formal auditability to stake its reputation - in case of emergency, credible exit even in the case described below, there is a story for auditability (see thread). plc read replicas shipped, governance and transparency logs ahead!

just added @standard.site support to my blog when I deploy a new version of my site, blog articles are automatically synced to my pds (npmx.social) ... and therefore immediately discoverable on any standard.site reader, e.g. @greengale.app ...

We've released a self-hostable reference implementation of a PLC read-replica service to make the Atmosphere ever more decentralized. @retr0.id has details on what this all means. atproto.com/blog/plc-rep...

We've been hard at work on a new website with new guides, better docs, more translations, even our very own blog. We think it looks pretty sharp, too. It's now easier than ever to just build things with AT Protocol. atproto.com

in atproto office hours folks asked about two-week session lifetimes for oauth public clients, such as SPAs. i spoke about a surgical little proposal to have our cake and eat it too: SPAs untouched but with client authentication! for those interested, here it is: github.com/bluesky-soci...

🔴 LIVE https://stream.place/pfrazee.com And we are live with office hours!

I can save bookmarks with @margin.at, file them in collections created with @semble.so, and both bookmarks and collections are visible in Margin and in Semble Oh, and if either Margin or Semble shut down, this wouldn't impact my data All of this dark magic is only possible thanks to AT Proto

hey we're really working on permissioned data! read the first in a series of posts i'll be doing about our design decisions along the way. this one is about our decision to not do an e2ee system

Hot off the internets — there's a brand new kid on the DASL block: Web Tiles! It's still early days, some key features are missing, and there are some rough edges, but you can publish tiles to AT and play with the idea! webtil.es

so, if you're on @tangled.org, we're there too! 🕸️ 👉 I just set up a read-only mirror of @npmx.dev for our friends there 🩵

@npmx.dev project landed over 700 PRs in the past two weeks from well over 100 contributors. so sick!

some thoughts on how to implement public community spaces in atproto. I think it is important for us to stretch what the protocol can do; and there are some great opportunities for self-hosting, moderation, customization, etc

so this is a thing now

Bluesky office hours on Streamplace this Friday!

I love this. atproto at its best nekomimi.leaflet.pub/3m6pcklmvt222

brew install goat goat firehose --verify-mst --relay-host wss://bsky.network

This transition is now complete. The 'bsky.network' firehose and jetstream instances are all functional. Connected services should have transitioned smoothly, though in some situations may require a restart.

we've rolled out support for @bluecast.app links in Live Now! bluecast.app is a super nice audio streaming app built on atproto — especially popular with many of our bsky friends in Japan

2026 is the year Bluesky and the Atmosphere really come alive here's what's next bsky.social/about/blog/0...

atprotoans using tap, important update here! if you build from source from indigo: git pull && git checkout tap-v0.1.4 go build -o tap ./cmd/tap <redeploy> if you run with docker: docker pull ghcr.io/bluesky-social/indigo/tap:latest <redeploy> (ensure to replace container!)

going to transition the 'bsky.network' relay firehose this coming week! should be smooth, but we'll be doing announcements and keeping an eye on the ecosystem when it happens

getting somewhere

I blogged! I blogged much too late in the day for non-Pacific time zones again! When will I learn??? Find out, on my blog!!

yall isn't it cool we get to rethink what hanging out together online looks like?

This is the most succinct version of a post I've been trying to write for two months. When I stop for just a sec to think about the possibilities of The Atmospheric web, I'm a little overwhelmed by how exciting it is. Come build it with us!

formats over apps

stream.place links are now supported in the Live Now beta! OTA update rolling out today. love what @iame.li's building. when you stream there, your LIVE status on Bluesky is auto-updated. very cool demonstration of how Atmosphere apps can interconnect and benefit each other.
