Sandstorm without self hosting has no interest though. (Edit: see below, where the creator states it _can_ be run locally)

Buzz looks like a more reasonable direction than this does.

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!”

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

Honestly it is faster running locally.

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.

That is actually cool.

Maybe it is my bubble, but the experience people are having with Anthropic particularly is motivating a big “get this stuff back under control” effort so while it may not be strategically optimal for Cloudflare the local hosting would prove more valuable to enterprises than maybe a few years back, even if presented as a backup plan.

Neat! How does that work with the AI Gateway portion? I see some references in the code but at a quick glance I can't tell if you can configure it to skip AI Gateway.

	▲	kentonv 5 hours ago \| parent [-]
		Use of Cloudflare AI Gateway is optional. In the default configuration, you just plop your Anthropic/OpenAI/Gemini/Workers AI/ollama API keys into the UI and it talks to each provider directly. That said, I would recommend AI Gateway, it has a lot of nice features. :)

You're not alone The name "cloudflare-os" by itself made me think this was heavily based on Cloudflare

Do you have a store/list of public blueprints like sandstorm?

▲

kentonv 5 hours ago | parent [-]

Not yet, but that's an obvious direction to take things. :)

I'm really excited by the idea that this platform makes it safe to use blueprints that someone else vibe coded, without worrying about whether they checked it for security bugs, etc. Basically if the app works, it works. So yeah, there absolutely should be a marketplace so everyone can try everyone else's stuff.

BTW there are three blueprints installed automatically (docs, slides, sheets).

Couldn't the blueprint exfiltrate incoming data to an external location for example?

		Blueprints shouldn't (if I know anything about Kenton) have access to the Internet/external locations without you granting it permission to.
	▲	kentonv 4 hours ago \| parent \| prev [-]
		The blueprint is just code, it does not include data or capabilities. It's, I suppose, possible that the agent added secrets to the code itself. Not, like, API keys -- the agent never sees those. But it could have extracted sensitive info and put it into code, perhaps? We can implement restrictions on exporting blueprints from workspaces that have seen sensitive secrets, though this might be more annoying than useful. It's a tricky balance.

Thank you for your work over the years, sandstorm is a really interesting and inspiring piece of software. I'll certainly try to self-host CloudflareOS.

Yes, just like SaaS was a limitation to it's utility, PaaS is still a limitation, just on a different level.

There is also qm with smol machines. I found this out the long way, by looking at the contributors to qm at https://github.com/yc-software/qm where I found BinSquare, the founder of smol machines. Then I found a tweet about a public instance of it where I could try out having it code something agentically - I'm in the replies here: https://x.com/binsquares/status/2083305704274976819

I guess the lock-in is to Cloudflare Workers, which is limited to JavaScript. I would in fact look into projects that are built around MicroVMs and WebAssembly. It seems Buzz would be happy to use smolmachines, or whatever. You'd have to roll your own permission system, but smolmachines would at least take care of being able to use stuff within an app, by offering persistent, portable containers.

Actually I think now I can finally say why this sandstorm.io with Cloudflare OS has lock-in. The promise is "you can pretty much go wild" and that you can hand it off to non-technical people to do that. Much as you squint, there is not a sophisticated access control system available to self-hosted users. There's a framework for building a sophisticated access control system, but that isn't the same as having something open source that you can self-host and let non technical users go wild.

However, this is cool. I just agree with you that Buzz sounds more interesting to me as someone who was into Sandstorm.

Workers also supports Python, Rust and anything via WebAssembly (Go, C, etc)

	▲	benatkin 2 hours ago \| parent [-]
		Ah, that changes the amount of work and the reward in the equation for attempting to self-host Cloudflare OS. And I knew that I could run WebAssembly manually inside of JavaScript, but it seems to be runnable directly too. What would help me to know further is how Cloudflare OS integrates its access control in that open source project, and if it is conveniently available to WebAssembly, Python, or Rust workers.
