Note that this is fundamentally different from the Astral acquisition. At the end of their announcement, they stated:

> Cirrus CI will shut down effective Monday, June 1, 2026.

And earlier in the article:

> Joining OpenAI allows us to extend the mission we started with Cirrus Labs: building new kinds of tooling and environments that make engineers more effective, for both human engineers and agentic engineers.

It isn't a product-led acquisition, but more a talent one.

troyvit•1 day ago

This is kind-of neat too, at least in the near term:

> In the coming weeks, we will relicense all of our source-available tools, including Tart, Vetu and Orchard under a more permissive license. We have also stopped charging licensing fees for them.

rmast•1 day ago

That part is amazing. Back when I first heard of tart I thought it was amazing, with the one downside being the license.

Hopefully development on it continues, or a community maintained version keeps it going.

Just want to note that we will continue maintaining and improving our virtualization solutions actually with even greater attention. SaaS options like Cirrus CI and Cirrus Runners will eventually wind down so we can focus on incorporating pieces internally.

I mostly clicked the link because I was curious if Cirrus Labs operates Cirrus CI and if so how that would be impacted.

Looks like I’ll need to move the FreeBSD CI jobs for open source projects I maintain to another solution. Anyone have suggestions for alternatives?

Same for me. I liked the native BSD runners, qemu on gh is much slower.

hirako2000•2 days ago

It could also be a suite of product acquisition, the CI could be a product OpenAI is interested in having, but not sell.

trollbridge•2 days ago

Yeah. Much like Astral - acquiring both the product (because they need to use it internally, but don't care about trying to resell / market), and they also want the talent to keep maintaining it / add features they want.

super256•1 day ago

>It isn't a product-led acquisition, but more a talent one.

I am pretty sure OAI mostly cares about their virtualization IP for MacOS. They already extensively use WSL2 for sandboxing Codex on Windows, and I imagine they want something similar for Codex on Mac.

I’m happy for the founders, they’re great folks. I contributed to CirrusCI a bit in the past and it was a great experience. I even advocated for Cirrus in a couple of my last $DAYJOBs (with varied success). Congrats Fedor!

I’m very sad they’re shutting down, though. IMHO CirrusCI was very close to a perfect CI system (I wrote a blogpost about it [0]). I’ll now have to find something to replace it with in my personal projects. I guess I’ll run their cirrus-cli in GitHub Actions for a while. But GitHub Actions is really poor. I heard some good things about Buildkite.

Having tried many other CI systems, all of which ultimately turned out to be subpar, it makes me incredibly sad to discover only now that Cirrus CI is (was?) quite a bit better than them. :( Thanks for the blog post, though!

tagraves•1 day ago

Well, check out RWX! We don't do exactly everything like CirrusCI did -- most notably, we aren't open source and we are still managing all of our own infrastructure for running CI right now -- but we have a great "local" story and a validation CLI (`rwx lint`), and a lot of fundamental changes that make us better than other CI systems too :)

Why would anyone move to a closed-source tool like yours? It's 2026.

FTA:

from Tart's github:

> [Tart is for] macOS and Linux VMs on Apple Silicon to use in CI and other automations

My (naive?) hypothesis is this kind of expertise is why OpenAI chose to acquihire.

threecheese•2 days ago

Same; the reason everyone ran out to buy Mac Minis last month is it gave their Claw access to iMessage, their browser cookies, and a residential IP. Cirrus provides a way to provision and orchestrate MacOS VMs, which is exactly what I did for running Openclaw (for a minute …).

dangoodmanUT•1 day ago

Note that apples terms do not allow someone to sell something like an agent running on macOS. They have explicit cut outs for 24-hour minimum leases of full hardware, but they prohibit this with vms

jen20•1 day ago

Not to sell Tart short (it is quite good), but it's "just" a wrapper around Virtualization.framework with a few extra pieces. This is the kind of thing that Codex driven by experts _should_ be able to build very easily.

w10-1•1 day ago

Agreed. The benefit from not having anyone else or any partial (container) solutions in the computing chain is huge for secure isolation. Getting rid of the intermediary solves a universe of possible problems.

That said, I've been free-riding on tart because they've often surfaced issues I needed to address. Free riders like me are possibly the reason these companies can't make their own way.

TheTaytay•1 day ago

Yes, but it’s also currently the best one. They have OCI compatible Mac VM images that are prebuilt. It’s quite good.

I liked “our incredible journey” more when it wasn’t rushing headlong into OpenMawAI

jeltz•2 days ago

Every great journey must have an end. As far as I understand Cirrus CI was struggling due to Github Actions eating their market. Cirrus CI was in my opinion much better than Github Actions but it is hard to compete with a bundled solution.

esafak•2 days ago

What was good about it? It looks pretty ordinary to me: https://cirrus-ci.org/features/

anarazel•about 23 hours ago

Ability to trivially use custom VM images was quite nice. The amount of CI time spent installing dependencies or copying a cache of installed stuff is nontrivial. Particularly for Windows the time difference is often very substantial. But even for plain Linux, there's no point in apt-get update && apt-get install the same set of things in every run (when using containers, cirrus could build them in-demand too, with little notational overhead).

Defaulting to throw-away-VMs for everything is also the right choice for something where the threat model includes attackers submitting patches/PRs. I'll never understand why folks were ok with just container separation for that (and often have no separation in runners).

a1o•1 day ago

It gives a better docker based experience and it also has measurements of memory and cpu usage to help you dimension things quickly.

trollbridge•2 days ago

The level of aqui-hires is getting interesting - at this point, it appears that if one wants one's career to progress, you need to start some kind of tiny startup like Astral or Bun and hope to be notable enough you can get acquired by someone like OpenAI or Anthropic.

It certainly makes the idea of a career progression / promotion more challenging than it used to be, but perhaps it also opens up some new opportunities. It becomes far more "high stakes" since you have to take the risk of starting and running a startup that ultimately fails if it does not get acqui-hired.

mcmcmc•2 days ago

It also kills competition and disincentivizes providing long term value. I’m not sure how making the job market more like gambling does anything positive for the majority of people

It’s been true for a while, but AI seems to have exaggerated it. To me it reinforces the idea that LLMs created a “K” shaped talent market. Those whose are good become even more valuable.

I've moved most companies away from using others stuff

Today we use Hertzner and OVH and roll out our own solution whenever possible.

Running lean and mean.

Depending on such third party services is a trap.

Aurornis•2 days ago

Been there, done that, and I still find value in 3rd party services despite the occasional need to migrate.

Self hosting is the way to go if you need to keep monthly services spend as low as possible but you have extra time to spend, such as with a hobby project.

Whenever I’ve worked on real startup projects, self-hosting became a constant source of little tasks for the engineering team to mix into our weekly workload. There were always little tasks to upgrade this service, investigate why that one server was slow, or to migrate something to a bigger server because we were bottlenecked on some resource. Then we had to manage backups and do our recovery drills, along with changing the backup strategy every 6 months because someone had a better idea.

When we started to add up all of the time spent managing everything it starts to look like spending dollars (of engineer time) to save pennies on SaaS bills.

Probably not a popular thing to say on HN, but I now try to stay away from teams that go to extremes to self-host everything because I just want to get my work done, not also be constantly involved in running the underlying services. I do it for my own hobby projects at home but I don’t want to be doing it at work where we have money to spend to lighten the load. If the cost is the occasional migration to a different 3rd party service that’s not a big workload relative to everything involved in self-hosting.

faangguyindia•1 day ago

>if you need to keep monthly services spend as low as possible but you have extra time to spend, such as with a hobby project.

We did not have any budget constraints at all.

Depending on 3rd party meant:

1. Begging for issues where project owner has marked them "won't fix"

2. Navigating hundreds of features we don't use, don't need and not having features we absolutely need but they don't have.

3. Weird gotchas and cost saving implemented by them, where we do not want to save any money.

>When we started to add up all of the time spent managing everything it starts to look like spending dollars (of engineer time) to save pennies on SaaS bills.

We actually factored all costs, our self hosted solution are "very lean" and still come out ahead when you factor in time/cost.

>spending dollars (of engineer time) to save pennies on SaaS bills.

I ran by this for long time fasely believing "engineers are way more expensive than cloud bills, so these thousands of dollars we are spending on these services don't matter"

but when we actually got down to fixing all , we realised now it costs us 1/10th of what it used to with more flexibility and reliability.

>Probably not a popular thing to say on HN, but I now try to stay away from teams that go to extremes to self-host everything because I just want to get my work done, not also be constantly involved in running the underlying services

we found exact opposite tbh, integrating into others hurt our performance, wasted our time, made us frustrated and desperate.

Only external service we use now are Anycast for serving our sub millisecond api and "billing", yes billing because it has lots of edge cases, taxes and all wicked things we can't manage on our own.

Still looking to rollout inhouse biller soon though.

greybeard26•1 day ago

... please keep doing backups and DR tests.

causal•2 days ago

That is something of a broken promise in the SaaS world; it was supposed to be convenience but instead it became a hundred broken integration points as you struggle to keep up with deprecated APIs and acqui-hires killing off shims you wouldn't have needed if everything had been on-prem to begin with.

What software do you use to run your CI?

rglullis•1 day ago

Not OP, but to me the answer is:

  - gitea
  - woodpecker CI
  - my own docker registry
  - portainer running on my docker swarm

I then define the docker stack in the git repository, and CI builds the images and pushes to build the new image to the docker repository. The portainer API allows to deploy a stack, with the image tag as a parameter.

zackify•1 day ago

not op either, github actions, self hosted runner on bare metal with lxc containers for each runner.

Cost savings are insane and the speed of latest amd epycs are miles ahead of the default ci instances on github and other places.

It looks like OpenAI has no clue what to do and does what every software company without a plan does: create new dev tools and a new dev stack.

So they want an integrated solution with CI, Python packaging and vibe coding.

Cirrus gave a ton of support for years to open source projects. I congratulate them on cashing out. Running a business like Cirrus did is always a hard road and I will never fault folks who gave time and resources on their platform away for taking the money.

I wish Fedor and everyone at Cirrus the best of luck and OpenAI and thank them immensely for the years of free CI they gave to us in the Pony programming language despite it not having any marketing value to them.

Wow Cirrus was like the one cool CI thing with first-class Podman support. RIP. Guess I'm looking elsewhere (and not at Dagger which refuses to support rootless Podman).

I mean, yes it is, but we all know what happens to these projects when their primary devs move on or get acquihired. Keybase, anyone?

A pity. Cirrus has been providing quite decent CI facilities, for free. One of the advantages (among many) compared to GitHub Actions is the large variety of runner images, e.g., Debian, Fedora, Alpine, FreeBSD, ...

Can you talk a bit more about your journey without raising funds?

Also what does HN think of that path today when trying to launch a new AI startup?

fkorotkov•2 days ago

Thank you! Full journey is too long for a comment here.

It was hard and I was lucky with my previous pre-IPO gigs at Airbnb and Twitter so I had some bootstrap fund. In retrospective a dev tools startup in 2017 with no network and no VC support was a crazy idea but I was young and didn’t think thought too much.

Then it was long 8 years of raw work and constant questioning this choice. Then finally a third component: luck. In 2024-2025 it kind of grew organically due to market changes and back in October 2025 I finally stopped questioning the future of Cirrus Labs.

My only advice if I may, try to get your first dollar from your startup while you are employed.

dennisy•1 day ago

That is good advice!

I am too late for that as I am full time but also lucky to have had a previous exit.

I am planning to go the VC route this time, because the problem I am going after feels VC size.

However I feel bootstrap or small F&F round gives you more flexibility when it comes to exits.

Congrats again!

What was the USP of their CI service?

Maxious•2 days ago

Ability to virtualize on Apple devices and linux with GPUs https://github.com/scipy/scipy/issues/24990

rvnx•2 days ago

To create an ephemeral (docker-like) MacOS VM on a Mac with full performance and access (e.g. GPU) you have to use a virtualization API provided by Apple.

For most CI use, you can choose between:

  Anka, a "contact-us for pricing" closed-source projet, where you have to pay expensive license (easy 3000 USD/yr per machine)

  tart, which is a lightweight wrapper around the official Apple API.

But you have to know that on MacOS, there is an artificial limit of 2 VMs per Mac... but well:

https://github.com/cirruslabs/orchard/commit/3cfa2445500f45f...

With https://khronokernel.com/macos/2023/08/08/AS-VM.html

Some people might find it very attractive:

  Instead 25 Mac Mini you might need only 5.
  + No licensing to pay to Anka.

Even without bypassing the limit it is great actually

Look, I’d have done the same thing, I’m not criticizing the choice. I just think we don’t need this kind of weird unnatural rhetoric.

Please just stop with the tech industry puffery. You’re not Steve Jobs, you’re just the DevOps team at OpenAI now. You’re dumping your worthless code on GitHub, and you’re kicking your customers to the curb.

There is a theme in a lot of products (and open source projects) of plastering AI all over the description, even if it isn't really related to AI.

How am I supposed to know this is a CI product, and even if I figure that out, how am I supposed to know it is a genral CI tool and not something AI specific?

I don't understand why these sites just put a bunch of buzzwords instead of telling you what it actually is.

Xiaoher-C•1 day ago

The projects that tend to get acqui-hired — Astral, Bun, Cirrus, etc. — share something specific: they solved a real problem that the acquirer depends on internally, and nobody else had solved it well enough. That's a different dynamic than "be notable and hope someone bids."

What's actually happening is that AI labs have infrastructure needs that don't map cleanly onto existing commercial products, so the fastest path to having the tool they want is to bring the team building it in-house. That's closer to procurement than a traditional acqui-hire.

Whether that's net positive for the ecosystem is genuinely unclear. You get a better-resourced tool in the near term. But you also get organizational risk: if the acquirer pivots or the team gets reassigned, the institutional knowledge goes with it. Tart being relicensed more permissively is the hedge against that scenario, and it's a smart move.
