Announcing the Cloudflare Data Platform: ingest, store, and query your data directly on Cloudflare
The Cloudflare Data Platform, launching today, is a fully-managed suite of products for ingesting, transforming, storing, and querying analytical data, built on Apache Iceberg and R2 storage.
Thanks for that post! It was a great help when I was building Cirrus
January 17, 2026 at 8:30 PM UTC I wonder what would be most useful to the ATproto ecosystem for Cloudflare to provide. Any thoughts @danabra.mov ?
January 17, 2026 at 6:46 PM UTC This is really cool. I like the way the agent skill is basically "run with --help"
January 17, 2026 at 10:19 AM UTC These were the suggestions from my Opus-based agent at the time. I ended up just making it easier to clear recent context, and refreshed the Telegram webhook which kept re-sending the bad message.
Every Friday, Cloudflare has a "dev platform demos" call that's just packed with back to back cool stuff. It's so exciting. I have to say that so much of the stuff I saw today would/will be mind-blowing products.
January 16, 2026 at 7:34 PM UTC Well, Cloudflare is undeniably the best place to host ATProto apps. The bosses are all still over on X though, sadly.
January 16, 2026 at 7:30 PM UTC I don't get into arguments about my employers, if that's what's going on!
January 16, 2026 at 7:27 PM UTC As my normal feed is now blissfully lacking in them, I can go and experience bad replies in a controlled way
January 16, 2026 at 7:22 PM UTC 100%. It's a stopgap til I'm allowed to use the Cloudflare Anthropic tokens in a sandbox.
January 16, 2026 at 7:17 PM UTC I block so freely. Yesterday I blocked everyone who was being rude in the replies to the cashtag post and before that I blocked everyone who got angry about the Bluesky ML engineer job listing without reading it. My feed is great.
January 16, 2026 at 7:13 PM UTC Nobody was as surprised as I was, which in retrospect is a bit silly
January 16, 2026 at 6:21 PM UTC I'm relying on the super cheap coding plan, which is why I'm using it
January 16, 2026 at 5:46 PM UTC They missed me so much, the whole Astro company followed me to Cloudflare.
January 16, 2026 at 2:16 PM UTC GLM-4.7 is a great value model for your stateful agent, but be careful to not brick it with wrongthink
His wasn't disgraceful, but it was ridiculous. He basically won it for not being GWB
January 16, 2026 at 9:03 AM UTC More people on the left need to read the Culture books. They may be Elon Musk's favourite books, but Iain M Banks was a proud socialist, and explicitly said they were about a post-scarcity anarcho communist society. Whatever happened to fully-automated luxury communism?
January 16, 2026 at 7:52 AM UTC Me when my phone turns off bedtime mode and the overnight news alerts arrive
January 16, 2026 at 7:42 AM UTC Mid 40s update: I put my shoulder out for a week throwing a ball for my dog.
January 16, 2026 at 6:28 AM UTC Have any other PDS developers had this: videos from Cirrus seem to disappear from the Bluesky CDN after a few days. Still in the PDS, and they work when first uploaded.
January 15, 2026 at 10:04 PM UTC Yeah, we use it to serialise content collections to disk, for server island props, and I think action responses. Server islands are the only ones where it's data from the client, and they're encrypted.
January 15, 2026 at 10:00 PM UTC Astro 6 beta is here! The biggest change is a completely new dev server. The old one pre-dates SSR in Astro and used different code paths. The new one uses the Vite Envirnment API to run the same code as SSR, reducing bugs and allowing stuff like running dev if different runtimes such as workerd.
January 13, 2026 at 9:02 PM UTC No moving after it's created, sadly. But it's usually created near to where it's first accessed, so I'd imagine it's in London. A fancy map here shows where they're created where.durableobjects.live

Cirrus PDS now supports specifying a placement region for your data. Give a region hint, or specify EU-only storage. 🥂 🇪🇺
What you mean you don't have a cool studio with breezeblock backdrops, just a cold garage with breezeblock walls?
January 13, 2026 at 4:26 PM UTC My problem is with the web and mobile version. I'm not sure how to make those ones switch
January 13, 2026 at 4:13 PM UTC You need your .dev.vars file. That has your secrets. It's very important you don't lose it. The signing key in particular because there's no way of recovering it! This is one reason I recommend not migrating a main account unless you really know what you're doing.
January 13, 2026 at 11:50 AM UTC ⚠️ JPEG XL landed in Chromium! ⚠️

Gerrit Code Review
npm i @getcirrus/pds@latest then npm run deploy (switch to pnpm, yarn etc depending on what you used to install)
January 13, 2026 at 11:45 AM UTC The relevant person isn't on Bluesky. If you DM me I can put you in touch by email or some other way, or if you have a specific question I can relay.
January 13, 2026 at 10:42 AM UTC In related news: Bluesky will refresh expired tokens that return a 401 or 400 when the page first loads, but in subsequent API calls it only refreshes if they return 400.
January 13, 2026 at 8:25 AM UTC Claude Code web/mobile etc uses Sonnet. This PSA brought to you by the debugging session that went around in circles for half an hour until I thought to ask it what model it was. CC from the CLI found the bug instantly.
January 13, 2026 at 8:25 AM UTC Cirrus is really buggy, but I'm automatically deploying from main so if it breaks I don't need to listen to any complaints
January 13, 2026 at 12:24 AM UTC Tell the others: AI is legal on Bluesky, and everyone is building stateful agents
January 12, 2026 at 4:11 PM UTC Niche thing that may help some people: if you have a headless Mac that will no longer boot without a password, you don't need to attach a monitor, you can login over SSH and it will then boot properly.
January 12, 2026 at 1:44 PM UTC Of course your data would still be mirrored to the US relays, but it would mean the source of truth location was controlled. Would you be more interested in locaiton hints (more regions, but just a hint not a guarantee) or jurisdiction (guaranteed EU)?
January 12, 2026 at 11:48 AM UTC Would people be interested in data placement location/jurisdiction support in Cirrus? By default Cloudflare places the Durable Object close to the place where it's first requested, but it is possible to give a hint about where to place it. You can also force it to place it in the EU. Worth doing?
developers.cloudflare.com
Data location
Jurisdictions are used to create Durable Objects that only run and store data within a region to comply with local regulations such as the GDPR or FedRAMP.
Should be fine. The secrets are in .dev.vars, which is gitignored. The published wrangler.jsonc includes your handle, DID and public key.
January 12, 2026 at 6:55 AM UTC Deliberately no. You can deploy another Worker if you want another account. I wanted to avoid complexity of account management, so it's single-user only
January 12, 2026 at 6:48 AM UTC Yes, Cirrus uses SQLite-backed DOs, which works great. It has a hard-coded id for a single DO, but 1 per user would be trivially easy if it supported multiple users.
January 12, 2026 at 6:09 AM UTC Cloudflare Durable objects are really the perfect platform for ATProto, and I said that before I started working here!
January 11, 2026 at 7:11 PM UTC Telegram. Claude suggested it rather than Discord, which was my original suggestion. The API is incredibly easy and I already use it.
January 11, 2026 at 6:51 PM UTC Zero. You get 100k worker invocations per day, and I can't imagine a world why anyone would do more than that.
January 11, 2026 at 6:50 PM UTC Reading them all like that makes it obvious I need to change them to all be verbs
January 11, 2026 at 5:29 PM UTC All commands that I ran: pnpm create pds@latest <- bootstrap the repo, build and deploy pnpm pds migrate <- copy across all posts, settings, media etc pnpm pds identity <- transfer the DID/handle to the new PDS pnpm pds activate <- enable pds & tell the network pnpm pds status <- check it works
January 11, 2026 at 5:20 PM UTC This is the complete, real migration of @mk.gg from the Bluesky PDS to a new Cirrus PDS Worker. The more boring bits are sped-up to get it under the 3 minute video limit. The real thing took about 12 mins. Try it yourself: github.com/ascorbic/cir...
Ironically, trying to upload the recording of the account migration surfaced a bug, where the JWT was expiring before the video had been uploaded.
January 11, 2026 at 4:57 PM UTC The full migration took around 12 minutes, almost all of which was waiting for the blobs to transfer.
January 11, 2026 at 3:25 PM UTC I did plan to post the full migration recording, but I think I'll skip this bit!
This is all run locally on your machine. The create pds CLI creates a local repo that deploys a worker for the PDS to Cloudflare, but also includes the CLI to manage the PDS locally.
January 11, 2026 at 2:55 PM UTC Funny I know exactly who you are talking about, despite not being aware of any such Twitter discussion
January 11, 2026 at 1:57 PM UTC Turns out there's nothing in the spec that means the token needs to be emailed, so instead I've implemented a stateless, HMAC-signed token that you get from the CLI. No email needed, and more secure anyway.
January 11, 2026 at 1:46 PM UTC I'll add more detail, but the cli should take you through the whole process
January 11, 2026 at 1:31 PM UTC Yeah, after trying and failing to remember the package name for the SSH client, I thought I'll just ask Claude to do it all. "Explore this environment and install the basics that we need"
January 11, 2026 at 1:01 PM UTC Oh, it worked fine for me (as you probably see). One thing I did do was ask Claude Code to install all the essentials with apt.
January 11, 2026 at 12:15 PM UTC OK, I just tested a full end-to-end migration from Bluesky to Cirrus. Deploying the Worker, migrating the repo, migrating out the DID from Bluesky, notifying the relays and checking the status. It took less then a minute, and was entirely done with the interactive CLI. Now to test migrate out.
January 11, 2026 at 12:14 PM UTC Yeah, and it asks for permission to open the port when you first click on a URL. Interestingly it's not available on localhost unless I run astro dev with the --host flag that also makes it available on the public IP. Then it's available on both.
January 11, 2026 at 10:50 AM UTC I was inspired to do it by Wes95 by @wes.dev

Architecture: @hono.dev and Cloudflare Workers for the APIs Cloudflare Durable Objects + SQLite for repo and pref storage, and firehose websocket server Cloudflare R2 for image and video storage Official ATProto libraries where possible for everything protocol-related
January 4, 2026 at 9:55 AM UTC You can migrate between them, but not have more than one live at a time
January 4, 2026 at 9:49 AM UTC I think you're misreading that sentence. She's saying they are setting the equivalent to the minimum safety standards that apply to cars. They're setting a baseline for all products that use their APIs. Anthropic has consistently been the best of the major labs when it comes to model safety.
January 4, 2026 at 7:11 AM UTC I've not done all the calculations, but this should fit easily within the Cloudflare Workers free plan. If it doesn't then it's probably a sign you should spend less time here
January 4, 2026 at 5:56 AM UTC I've not tried it with bun, so I'll look at that. There's nothing to see at the site root. It's all API calls. I should probably serve a page from there though.
January 3, 2026 at 9:21 PM UTC My experimental single-user PDS has a name! Meet ☁️ Cirrus, the lightest PDS in the Atmosphere npm create pds@latest
Has anyone ever explained why npm returns a 404 for auth errors when publishing?
January 3, 2026 at 5:47 PM UTC Monkey paw curls: how about three then. Taiwan is hardly sleeping easy right now
January 3, 2026 at 9:10 AM UTC (Just pointed Claude at @timkellogg.me's blog and told it to do some reading and get on with it)
January 2, 2026 at 10:30 PM UTC Took a break from building a PDS like everyone else to build a stateful agent assistant like everyone else.
January 2, 2026 at 10:27 PM UTC I suppose statistically it's always lots of people's first day on the internet, but the replies to @bsky.app sure do have a lot of people being confused by their first day on the internet
January 2, 2026 at 10:21 PM UTC I switched to For You a few months ago and it's been my default ever since. It's so much better than the alternatives.
January 2, 2026 at 7:14 PM UTC I don't really get the point of this piece. Ads may not make sense to you if you're not the target audience. Doesn't make them slop. The only takeaway is that these b2b services have margins high enough to justify subway ads even with a very low hit rate
January 1, 2026 at 11:19 PM UTC It does include all the Murderbot books, most of which are novellas.
January 1, 2026 at 11:03 PM UTC I thought it was great, despite the rest of the season being a bit meh. Pleasantly surprised.
January 1, 2026 at 5:24 PM UTC I'm still building it at the moment. You can try it by running "pnpm create pds", but it's still very much a work in progress so don't use it for anything important
January 1, 2026 at 3:52 PM UTC This runs on a Cloudflare worker. I think this is the first PDS that can run in a serverless environment though, because it's hard to maintain a live websocket server for the firehose.
January 1, 2026 at 3:01 PM UTC Thanks! Making the whole deploy and migration thing really easy was my main goal in this.
January 1, 2026 at 2:54 PM UTC It's going to be very easy to migrate to my PDS, and you can try it out in dev first. Here's an end-to-end migration of @mk.gg to my local dev server. All real, all real-time except media download which I sped up.
It depends on a dozen or so of the atproto libs, so I think that one is off the table
January 1, 2026 at 12:00 PM UTC It's not called myPDS after the possessive pronoun. It's actually named after My Widenius.
January 1, 2026 at 11:29 AM UTC Maybe just exclude common false positive TLDs from protocol-less detection. For English, ignoring .no, .me, .it and .to would catch most mistakes.
December 31, 2025 at 1:42 PM UTC They don't stop when they lose signal. They work in tunnels and other places without signal or GPS. The computer is onboard. They do stop at junctions where the lights have failed.
December 31, 2025 at 1:38 PM UTC I should probably come up with a name for my single-user PDS software, rather than just calling it "my PDS". Though myPDS has a ring to it
December 31, 2025 at 8:05 AM UTC This is really cool, and also the exact opposite of what I'm trying to do with my PDS. This is like the reference PDS with all the extra bells and whistles, while mine is like the reference PDS minus bells and whistles
December 30, 2025 at 6:34 AM UTC I'm not sure they are more energy efficient tbh. The hosted models can make better use of resources, with higher utilisation. The exception might be if you live somewhere with a particularly low emission power grid.
December 29, 2025 at 7:18 PM UTC I'm using a durable object which can maintain the firehose websocket, as well as the SQLite db that stores the repo. Otherwise it's fine to run on demand. The durable object supports hibernating websockets, so it's very resource-efficient.
December 29, 2025 at 3:07 PM UTC Yeah, it took me a few (Claude-assisted) days. Keeping the scope narrow helped a lot
December 29, 2025 at 1:31 PM UTC There are docs for the endpoints but none that I found that are very helpfully organised into which is responsible for what part. In the end I mostly got it from the atproto repo, and then implemented others that I'd missed when I got errors. It needs to proxy the rest to Bluesky.
December 29, 2025 at 12:46 PM UTC I'm creating a new PDS implementation, but using the official libraries wherever I can. e.g. all the repo/MST stuff, crypto and CBOR stuff use the official libs. The XRPC server stuff is mostly new, as is storage, auth etc
December 29, 2025 at 9:48 AM UTC I'm taking the "personal" in my PDS to its ultimate conclusion : it's single user only. If you want to support another user, deploy another copy. This greatly simplifies the implementation. Being able to do this at no extra cost is a huge benefit of using a serverless architecture like Workers
December 29, 2025 at 8:59 AM UTC Yeah, there is quite a bit of that in there. It definitely comes across as something where portability was an afterthought. I've been using the official libraries for everything except the PDS itself, which I'm basing on Hono, with Durable Objects for state and websocket handling
December 28, 2025 at 9:27 AM UTC Their market share in chat is much lower, but not in API use. Claude is one of the most popular models for coding, which is a huge market and almost all paid usage. They ary burning cash though, because they're spending billions on training new models.
December 28, 2025 at 5:45 AM UTC It was annoying, but did remind me of early Twitter where people were inventing retweets, @mentions and hashtags before they added them to the platform
December 26, 2025 at 8:32 AM UTC Yeah. Even if he just thought that it's some linear algebra analysing the internet, I'd expect he'd find it nice that the result of the calculation was that his work deserved a Christmas day thank you email. Or at the very least find it interesting.
December 26, 2025 at 6:50 AM UTC It wasn't even Anthropic. It was this interesting project where several agents have shared access to a computer. Claude chose to send the emails. theaidigest.org/village/goal...

The story of how the AI agents did on their goal.
They are useless. Gemini can identify its own creations, but any other AI detector is no better than guesswork
December 25, 2025 at 5:21 PM UTC Making "For you" the default with some bootstrapping for new users would make so much difference
December 25, 2025 at 4:36 PM UTC I reckon, though I have to admit I'm craving herring now. I need a trip to IKEA.
December 24, 2025 at 4:39 PM UTC I mean, I like herring, but that's a lot of herring and not a lot of charcuterie
December 24, 2025 at 4:10 PM UTC It's that time again! I made this about 7 years ago and it's still the most useful thing I've built.
December 24, 2025 at 3:12 PM UTC Durable objects are great for stateful stuff like this, and you can do long running websockets very cheaply
December 23, 2025 at 1:45 PM UTC If I had to predict which current website will still be around in 50 years (on whatever the web is), that's the only one I'd be confident of
December 23, 2025 at 8:49 AM UTC Two weeks off work means I'm bound to be tinkering. Thinking of building a little PDS that runs on a Cloudflare Worker. Anyone tried this? It should be a good platform for atproto stuff.

I really think you need to try a current LLM in research mode. Your impression is completely out of date.
December 21, 2025 at 6:32 PM UTC This is simply outdated information. Current LLMs will all use search tools to do research, visit web pages, and provide links to citations. They don't rely on their training data for facts.
December 21, 2025 at 6:10 PM UTC That's a very bold, very specific claim. Got anything to back that up?
December 21, 2025 at 5:16 PM UTC I actually liked it, and I have massive hands! Not enough to ever choose a small mouse again, but I definitely preferred it to the Mighty Mouse and Magic Mouse.
December 21, 2025 at 2:02 PM UTC Those were both great, but the original iMac remains the coolest piece of tech I've ever owned.

The worst is when it forgets it's already running and ends up with dozens of instances running on different ports in the background
December 20, 2025 at 11:58 AM UTC At least it got the megalopolis ZurichAmsterdam in the right place

December 18, 2025 at 10:29 PM UTC Pages isn't going away, but Workers is the best choice for new projects.
December 18, 2025 at 10:21 PM UTC Total energy use is indeed very high, but that's because hundreds of millions or even billions of people are using it. But as a percentage of a person's own energy usage or environmental impact it's tiny, and focusing on individual use is a distraction from more important issues
December 18, 2025 at 5:11 PM UTC If you're referring to training, the energy use is indeed massive, but it's amortised across billions of interference requests, so per query is absolutely tiny compared to the direct usage.
December 18, 2025 at 4:33 PM UTC A typical LLM query uses about 0.3WH, which is about 30 seconds of laptop use, so doing research the hard way certainly uses more energy. I can offset it by driving my EV 2 meters less next time, or turning off my kettle half a second earlier.
December 18, 2025 at 8:27 AM UTC They provide links, and they're good at it now. They used to be bad at it, but they're loads better now and you can click through and check.
