What do you mean? This is 100% open source and self-hostable! https://github.com/cloudflare/cloudflare-os It runs on the open source Workers Runtime: https://github.com/cloudflare/workerd You can run it at home if you want. There's even a Home Assistant Gatekeeper.

So you can run it off the public internet with no sneaky external dependency on cloudflare, slack etc? And it would be functionally the same? With the same performance if you put enough hardware there? If so cool, and that should have been clearly in the announcement, because as it sounded it is “I am a sucker, lock me in!”

> So you can run it off the public internet with no sneaky external dependency on cloudflare, slack etc?

Yes. It even supports ollama and works decently well with some local LLMs.

> And it would be functionally the same? With the same performance if you put enough hardware there?

Honestly it is faster running locally.

> If so cool, and that should have been clearly in the announcement,

We had so many things we wanted to say, it was hard to fit them all into one story.

The blog post is for an enterprise audience. My tweet thread is for the hacker audience.

This is effectively a Codex/Claude app competitor. Good move from Cloudflare since it helps them sell their core infra offerings. I like the direction they’re going with access control.

Yep, a pre-wrapped Codex for enterprise. Seems like the logical evolution from setting up an MCP.

Codex for enterprise is Codex for enterprise.

Everytime I read about new things from Cloudflare they look really cool but I cannot shake the feeling of not wanting to use them for fear of lock-in, am I too paranoid?

Yes. Be locked in. It's better to go 100% and only pay the switch costs if you have to.

Developing abstractions to let you switch technologies has 2 costs: The actual development, and not fully utilizing a specific technology. Lots of people prefer pain in small doses because it can be rationalized as eventual payoff.

There are degrees of this decision, of course, but I would say most folks worry too much about this particular champagne problem.

> the sandbox is so secure that you can pretty much go wild -- the AI cannot introduce a significant security bug. This can only be correct when the application can’t affect anything outside the sandbox. Which would significantly restrict useful applications.

See my next tweet in the chain: https://x.com/KentonVarda/status/2084990302784307363 ------------- Of course, personal apps are more useful if they can connect to external services. Cloudflare OS introduces a "connector" system we call Gatekeepers. This is sort of like MCP (and MCP is supported as a kind of Gatekeeper), but with a lot more: * Instead of exposing tools, a Gatekeeper exposes a Cap'n Web RPC API. That m…

> * When an action requires approval, the agent does not need to stop and wait for it. A Gatekeeper will simulate the outcome, allowing the agent to keep running and queue up more work. You can then approve everything in a batch at the end. Hopefully, this means you no longer feel the need to turn on auto-approve! (But you still can if you want.)

Can you say more about how you simulate outcomes of approvals? For example, if I need an approval to be granted permission to read a document, how could it simulate the document contents?

I liked Kenton's take on this: https://x.com/KentonVarda/status/2084990137180590572?s=20 Text from tweet: Today we are releasing Cloudflare OS, a chatbot with connectors, just like every other tech company is doing. Except actually, it's different. This is a remake of Sandstorm[.]io, my startup from 10 years ago, except this time built on Cloudflare Workers (the platform I've spent the last 9 years building) and deep…

That should have been the announcement. The article posted buries the lead. Cloudflare OS reads like almost any other AI knowledge base until midway when apps are introduced and then becomes overly technical with a code snippet.

We really struggled with how to present this to multiple audiences at once.

My tweet thread, and the GitHub readme, is really the presentation intended for the HN crowd. The blog post is for a different audience.

I feel exactly the same. The CF services I do use are DNS and R2. I'd be curious if there's a guide somewhere that lists their services through the lens of lock-in. For example, R2 is somewhat S3 compatible so it's less risky to use because I can swap providers.

> What if, when you wanted a new feature in the software you are using, you could just prompt your agent to add it?

Yep, that's precisely the vision I formulated some months ago: https://manuel.kiessling.net/2025/11/04/what-if-software-shi...

Ah look, yet another one jumping into AI party.

This is the middle of Cloudflare's "Agents Week"... and I believe they had an Agents Week last year. We're like... at least a year or two into Cloudflare being in the AI party. ;)
